Why Is Water So Important? Here’s What You Need to Know

How water works in your body, how much water do you need, how to stay hydrated.

Water is a major component of your body, accounting for 50–60% of your total weight. It is vital for many important body functions, from flushing out waste to lubricating your joints.

Your body constantly loses water throughout the day through urinating, sweating, and breathing. You should consume enough water from foods and beverages daily to prevent dehydration .

This article covers research-backed reasons why your body needs water and how much you need each day.

All body cells, organs, and tissues require water to function. Generally, a person can only survive without water for a few days.  

It Maintains a Normal Body Temperature

Water regulates our internal temperature by distributing heat throughout the body and cooling it through perspiration (sweat).

When the body becomes too hot, it loses water through sweat . The evaporation of sweat from the skin cools the body, keeping its temperature within a normal range.

If a person becomes dehydrated, they can't produce enough sweat to cool their body. This can cause the body's temperature to reach dangerous levels, leading to heat stroke .

Avoid dehydration by drinking plenty of water if you're working outside or sweating more than usual.

It Protects Your Joints, Spinal Cord, and Other Tissues

Water acts as a lubricant in the mouth (through saliva ) and the eyes (through tears) to help prevent dryness. It's necessary to produce synovial fluid , which lubricates, cushions, and protects the joints.

Water also helps protect the spinal cord and prevents injuries by increasing tissue flexibility and elasticity.

It Transports Nutrients and Gets Rid of Waste

As a major component of blood, water helps transport nutrients and oxygen to cells throughout the body. Water also helps carry waste from the body for excretion through perspiration, urination, and bowel movements.

The kidneys need water to effectively filter waste from the blood and flush it from the body as urine. Staying adequately hydrated helps prevent kidney stones and urinary tract infections (UTIs) , which can harm the kidneys.

Prevents Dehydration

Drinking water daily can help prevent dehydration, a condition that occurs when you lose more fluids than you absorb.

Early signs of dehydration include:

• Feeling thirsty
• Dark-colored urine
• Urinating less than usual

Because water is involved in so many body functions, dehydration can eventually cause life-threatening symptoms, including:

• Rapid breathing
• Rapid heartbeat
• Inability to urinate

People who exercise in the heat, work outdoors, or have certain health conditions that cause them to urinate or sweat more than usual are at a greater risk of dehydration.

It Aids Digestion

Your saliva is primarily made up of water. Saliva is a digestive juice that moistens food, allowing it to move easily through the esophagus into your stomach. Saliva also contains enzymes that help break down starches in food.

As the digestive process continues, water helps break down food, allowing your body to absorb nutrients. Water also makes bowel movements easier.

It Protects Against Chronic Illness and Boosts Longevity

Adequate hydration is linked to healthy aging and longevity. One potential reason for this is that decreased water intake can lead to higher sodium concentrations in the blood, which raises the risk of chronic disease.

Studies suggest that adults who stay hydrated are healthier and less likely to develop chronic diseases, including heart and lung disease . Well-hydrated adults also seem to live longer than adults who don't consume enough fluids.

It Improves Mood and Cognitive Function

Dehydration may cause fatigue and confusion and may be linked to symptoms of anger and depression. In a small study, it was linked to poor cognitive function, potentially affecting attention span and working memory.

One study of young adults looked at the effects of water on cognitive performance and mood after 12 hours of water restriction. Researchers found that 200 milliliters of water improved thirst, anger, fatigue, and overall mood. However, 500 milliliters was optimal, improving mood and cognitive performance.

The amount of water you need depends on several factors, including age, sex, activity level, and health status.

For healthy individuals, the adequate daily water intake is around 11.5 cups for women and about 15.5 cups for men. This includes fluids consumed from all foods and beverages.

Experts estimate that most people get around 20% of their daily water intake from food. This means women should drink about 9 cups of fluid daily, while men should aim for 13 cups to maintain adequate hydration.

People who live in warmer climates, are more physically active, or are experiencing an illness that causes fever and/or diarrhea or vomiting have increased fluid needs.

One easy way to see if you are properly hydrated is to check the color of your urine. If you are drinking enough water, your urine will be pale yellow. If it is dark, you may need to increase your consumption.

Individuals with heart failure or kidney disease may need to limit their fluid intake.

Can You Drink Too Much Water?

Drinking too much water can lead to water intoxication or overhydration, which occurs when the kidneys cannot flush out excess water. This can cause a medical emergency due to decreased sodium concentrations in the blood ( hyponatremia ). To avoid water intoxication, do not drink more than 48 ounces, or six cups, per hour.

If you find it challenging to stay hydrated, here are some helpful tips to keep in mind:

• Keep a reusable water bottle with you and refill it throughout the day
• Choose water or sparkling water instead of sugary beverages
• When you feel thirsty, drink water
• Change things up by squeezing fresh lemon or lime into your water or adding a few berries or cucumber slices
• Snack on water-rich fruits and vegetables , including watermelon, cantaloupe, lettuce, and celery, throughout the day
• Keep track of your water intake by using a water tracker app
• Drink water with all meals

Water is vital for your health. It is necessary for temperature regulation, digestion, nutrient absorption, and body waste removal. Drinking water daily can prevent dehydration, a condition that can cause mood and memory problems, constipation, and kidney stones.

People who work in high temperatures, exercise at high intensities, or are sick are at a greater risk of dehydration. Talk to a healthcare provider or registered dietitian to determine the right amount of water for you.

Lesson Overview

This lesson helps young people understand why drinking water is important. An Interactive whiteboard lesson teaches facts about the body’s need for water and offers tips to help the youth to drink more water. Using actual healthy and dehydrated plants reinforces the message that all living things need water!

Introduction

Here are some facts to share with the youth about the importance of water.

• Every part of your body needs water. In fact, water makes up 60 percent of body weight.
• Dehydration happens when there is not enough water in your body.
• Mild dehydration can cause headaches, nausea and fatigue (tiredness). You may need more water in hot temperatures or if you sweat a lot.
• If you’re getting enough water you’ll rarely feel thirsty. Your urine will also be clear or slightly yellow. Dark yellow urine is a sign of dehydration.
• There has been a significant rise in the intake of beverages with added sugars and excess calories on the market. Most are geared to entice children to consume. These added calorie beverages are contributing to overweight and obesity in our children.
• Drinking more water is one of the simplest things you can do to be healthier.

Activity: Plants

•  wouldn’t grow normally
•  may even die.
• Show young people the healthy and unhealthy plant. Point out the differences between the healthy watered plant and the unhealthy plant.  Healthy plants are full of color and stand tall and firm. Unhealthy plants sag, lack bright color, look wilted or limp.
• What do you think may happen to our bodies if we stopped drinking mostly water and drank pop, fruit drinks, sports/energy drinks instead? Or if we simply stopped drinking much at all? The answers are the same as for animals, babies and plants, but may include more diseases, injuries, our organs not working right, headaches, not thinking as clearly, or extra weight. Drinks other than water have added ingredients that can get in the way of the water’s ability to do what it’s supposed to do for us.

Water is what human beings, animals and plants were meant to drink! Drinking water actually helps you stay healthy!

Activity: Getting Enough Water

Use the interactive whiteboard, if available, to guide the youth through the following questions in the lesson (see What You Need).

• What percentage of our bodies are made up of water? Correct answer: 60%
• Why do you think we need to drink water when our bodies already have so much of it? The answers may include the information listed in the introduction above.
• So, we know that water is good for us, but do we know why? Ask the youth what they think water actually does in the body, and which things it doesn’t do.
• Keeps our body temperatures normal
• Lubricates and cushions joints
• Makes your hair grow faster (false)
• Helps your kidneys work correctly
• Makes you sleepy (false)
• Protects your spinal cord
• Helps digestion
• Helps your body get rid of waste
• Helps you float better when you are swimming (false)

Ask young people for ideas or tips they have for drinking more water each day. Possible ideas include:

fill a reusable water bottle and take it with you when you go places

drink water and milk with every meal

drink a glass of water when you wake up in the morning

keep cold water in a pitcher in the fridge.

Clean Water

Clean and safe water is essential for good health. how did access change over time where do people lack access.

Access to clean water is one of our most basic human needs.

But, one in four people in the world do not have access to safe drinking water. This is a major health risk. Unsafe water is responsible for more than a million deaths each year.

In this article, we look at data on access to safe water and its implications for health worldwide.

Unsafe water is a leading risk factor for death

Unsafe water sources are responsible for over one million deaths each year.

Unsafe water is one of the world's largest health and environmental problems – particularly for the poorest in the world .

The Global Burden of Disease is a major global study on the causes and risk factors for death and disease published in the medical journal The Lancet . These estimates of the annual number of deaths attributed to a wide range of risk factors are shown here.

Lack of access to safe water sources is a leading risk factor for infectious diseases, including cholera, diarrhea , dysentery, hepatitis A, typhoid, and polio . 1 It also exacerbates malnutrition and, in particular, childhood stunting . In the chart, we see that it ranks as a very important risk factor for death globally.

The global distribution of deaths from unsafe water

In low-income countries, unsafe water sources account for a significant share of deaths.

Globally, unsafe water sources account for a few percent of deaths.

In low-income countries, it accounts for around twice as many deaths .

In the map here, we see the share of annual deaths attributed to unsafe water across the world.

When we compare the share of deaths attributed to unsafe water either over time or between countries, we are not only comparing the extent of water access but its severity in the context of other risk factors for death. Clean water's share depends not only on how many die prematurely from it but also on what else people are dying from and how this is changing.

Death rates are much higher in low-income countries

Death rates from unsafe water sources give us an accurate comparison of differences in mortality impacts between countries and over time. In contrast to the share of deaths that we studied before, death rates are not influenced by how other causes or risk factors for death are changing.

In this map, we see death rates from unsafe water sources across the world. Death rates measure the number of deaths per 100,000 people in a given country or region.

What becomes clear is the large differences in death rates between countries: rates are high in lower-income countries, particularly across Sub-Saharan Africa and Asia. Rates here are often greater than 50 deaths per 100,000 people.

Compare this with death rates across high-income countries: across Europe, rates are below 0.1 deaths per 100,000. That’s a greater than 1000-fold difference.

The issue of unsafe water sources is, therefore, one that is largely limited to low- and lower-middle-income countries.

We see this relationship clearly when we plot death rates versus income, as shown  here . There is a strong negative relationship: death rates decline as countries get richer.

Access to safe drinking water

What share of people have access to safe drinking water.

Sustainable Development Goal (SDG) Target 6.1 is to: “achieve universal and equitable access to safe and affordable drinking water for all” by 2030.

Almost three-quarters of the world's population uses to a safely managed water source . One in four people does not use a safe drinking water source.

In the next chart, we see the breakdown of drinking water use globally and across regions and income groups. We see that in countries with the lowest incomes, less than one-third of the population uses safely managed water. Most live in Sub-Saharan Africa.

The world has made progress in recent years. Unfortunately, this has been very slow. In 2015 (at the start of the SDGs), around 70% of the global population had safe drinking water. This has slowly increased over recent years.

If progress continues at these slow rates, we will not reach the target of universal equitable access to safe and affordable drinking water by 2030.

In the map shown, we see the share of people across the world using safe drinking water facilities.

How many people do not have access to safe drinking water?

In the map shown, we see the number of people across the world who do not use safe drinking water facilities.

Improved water sources

What share of people do not use an improved water source.

The definition of an improved drinking water source is: “...those that have the potential to deliver safe water by nature of their design and construction, and include: piped water, boreholes or tubewells, protected dug wells, protected springs, rainwater, and packaged or delivered water.” Note that usage of drinking water from an improved source does not ensure that the water is safe or adequate, as these characteristics are not tested at the time of the survey. However, improved drinking water technologies are more likely than those characterized as unimproved to provide safe drinking water and to prevent contact with human excreta.

In the map shown, we see the share of people across the world who do not use improved water sources.

In the map shown, we see the number of people across the world who do not use an improved water source.

What determines levels of clean water usage?

Usage of improved water sources increases with income.

The visualization shows the relationship between usage of improved water sources versus gross domestic product (GDP) per capita. We see that there is a general link between income and improved water source usage.

Typically, most countries with greater than 90% of households with improved water have an average GDP per capita of more than $10,000 to 15,000. Those at lower incomes tend to have a larger share of the population without access.

Although income is an important determinant, the range of levels of usage that occur across countries of similar prosperity further supports the suggestion that there are other important governance and infrastructural factors that contribute.

Rural households often lag behind in improved water usage

In addition to the large inequalities in improved water usage between countries, there can also be large differences within countries. In the charts, we plotted the share of the urban versus rural population with usage of improved water sources and safely managed drinking water, respectively. Here, we have also shown a line of parity; if a country lies along this line, then access in rural and urban areas is equal.

Since nearly all points lie above this line, with very few exceptions, usage of improved water sources is greater in urban areas relative to rural populations. This may be partly attributed to an income effect; urbanization is a trend strongly related to  economic growth. 2

The infrastructural challenges of developing municipal water networks in rural areas are also likely to play an important role in lower usage levels relative to urbanized populations.

Definitions

Improved water source : "Improved drinking water sources are those that have the potential to deliver safe water by nature of their design and construction, and include: piped water, boreholes or tubewells, protected dug wells, protected springs, rainwater, and packaged or delivered water"

Usage of drinking water from an improved source does not ensure that the water is safe or adequate, as these characteristics are not tested at the time of the survey. However, improved drinking water technologies are more likely than those characterized as unimproved to provide safe drinking water and prevent contact with human excrement.

Safely managed drinking water: "Safely managed drinking water" is defined as an "Improved source located on premises, available when needed, and free from microbiological and priority chemical contamination."

'Basic' drinking water source: an "Improved source within 30 minutes round trip collection time."

'Limited' drinking water source: "Improved source over 30 minutes round trip collection time."

' Unimproved' drinking water source: "Unimproved source that does not protect against contamination."

'No service': access to surface water only.

• Revised Lead and Copper Rule: Testing at schools and child-care facilities As schools begin returning to session, water utilities across the United States are busy preparing for fall 2024 when the U.S. Environmental Protection Agency’s Lead and Copper Rule Revisions (LCRR) will require a new level of communication and cooperation with schools and child-care providers. School districts can be great partners, providing utilities a way to tell their water story through public education and inspiring a new generation who may one day be water operators. But schools operate very differently than many government agencies – from their funding sources to staffing and overall culture. Getting ready to be LCRR compliant means water systems must pay special attention to the needs of school districts and how to best collaborate with them.  Water utilities are required to provide schools and child-care facilities with a copy of EPA’s Training, Testing and Taking Action (3T’s) for Reducing Lead in Drinking Water in Schools and Child Care Facilities, as part of the LCRR sampling process. Utilities must sample at least 20% of elementary schools and 20% of child-care facilities in their service areas for the following five ...
• News reports on lead in Detroit schools Water utilities should be aware of current news reports on a decision to shut off access to drinking water in Detroit schools. With the start of the new school year, these stories may prompt questions from media and customers in other communities about lead levels in schools. Water utilities should be prepared to express their commitment to protecting children from lead in drinking water, including describing how they communicate with schools and daycare facilities in their service areas. Key points to elevate include: •    Our first priority as water providers is the protection of public health. •    Lead is typically not found in the water leaving our treatment or traveling through water mains. However, it may be present in school plumbing, as well as drinking water bubblers or coolers. •    Our utility takes the following steps to assist schools in understanding and managing lead risks from drinking water [if applicable, provide examples of letters to school districts, sampling guidance, etc.] •    EPA developed a guidance document titled 3Ts (Training, Testing, Telling) for Reducing Lead in Drinking Water in Schools, which outlines ...
• Operator-in-training courses taught in high schools By Ann Espinola Darrell King has a big job. He’s head of the water utility in Evanston, Ill. where he oversees nearly three dozen employees and a treatment plant serving more than 400,000 customers. But he spends every Saturday morning in a North Chicago classroom, where he teaches high school students how to become water treatment operators.   The program is one man’s way of forestalling the impending water sector labor shortage created by Baby Boomer retirements, and giving back to the community where he grew up. It is also among a handful of high school operator-in-training programs throughout the United States. In Texas, for example, water utilities in Irving and Arlington are working with their local school districts to prepare graduating seniors to pass water and wastewater licensing exams. In Portland, Ct., the city, utility and local school district partnered seven years ago to offer an operator course at the high school, but the program was discontinued two years ago during a change in leadership at the utility. The city hopes to start it up again in January.  The Irving program began ...

And it’s a job most people don’t know much about. They think water goes down the drain or the toilet and that’s the end of it.” The Florida Section of American Water Works Association (FSAWWA) received the 2020 Section Education Award for its High School Academy Program. The need to hire well-trained operators to replace retiring employees is urgent — in AWWA’s 2020 State of the Water Industry, respondents ranked “aging workforce/anticipated retirements” as one of the top 10 challenges facing the water industry. “If we can find people who have already taken courses, taken exams, people who know what they’re getting ...
• Kids safe to sip from school faucets, thanks to CECorps and AWWA section The school serves students in kindergarten through eighth grade and hosts community activities. The water system in the building had intermittently experienced high concentrations of lead in its water supply, which comes from a single well. Samples from specific faucets had lead levels of 40 parts per billion (ppb), exceeding the State of Washington’s lead action level of 15 ppb (90th percentile). A CECorps team of PNWS-AWWA volunteers, led by Lynn Williams Stephens (pictured right) and John Roth (pictured below), visited the site in the fall of 2016 and initiated measures to correct the situation. “We wanted a project that helped a low-income community address a water quality problem and the State of Washington Department of Health referred us to this school,” said Stephens, who works at Brown & Caldwell in Seattle. “I can’t think of a more important place than a school to try to reduce lead exposure. This also opened my eyes to the small-scale water systems I didn’t even know existed.” Volunteers in action The school did not have a full-time water operator and relied on contractors.

Press Release | Water crises threaten world peace (report)

Paris, 22 March 2024 – The United Nations World Water Development Report 2024, published by UNESCO on behalf of UN-Water, highlights that tensions over water are exacerbating conflicts worldwide. To preserve peace, States must boost international cooperation and transboundary agreements.

“As water stress increases, so do the risks of local or regional conflict. UNESCO’s message is clear: if we want to preserve peace, we must act swiftly not only to safeguard water resources but also to enhance regional and global cooperation in this area,” said Audrey Azoulay, Director-General of UNESCO.

“Water, when managed sustainably and equitably, can be a source of peace and prosperity. It is also the literal lifeblood of agriculture, the major socio-economic driver for billions of people,” said Alvaro Lario, President of the International Fund for Agricultural Development (IFAD), and Chair of UN-Water.  

According to the new report published by UNESCO, on behalf of UN-Water, today 2.2 billion people still live without access to safely managed drinking water and 3.5 billion lack access to safely managed sanitation. The UN goal of ensuring this access for all by 2030 is therefore far from being attained, and there is reason to fear that these inequalities may continue to rise.

Between 2002 and 2021 droughts affected more than 1.4 billion people. As of 2022, roughly half of the world’s population experienced severe water scarcity for at least part of the year, while one quarter faced ‘extremely high’ levels of water stress, using over 80% of their annual renewable freshwater supply. Climate change is projected to increase the frequency and severity of these phenomena, with acute risks for social stability.

Girls and women are the first victims of a lack of water

The first impact is the deterioration of living conditions, leading to heightened food insecurity and health risks. Water scarcity also has consequences on social development, particularly for girls and women. In many rural areas, they are the primary water collectors, spending up to several hours a day on this task. Reduced access to water supply exacerbates this burden, which undermines women’s education, economic participation and safety. This may also contribute to the higher secondary school dropout rate among girls compared to boys.

The lack of water security has also been identified as one of the drivers of migration. This displacement can, in turn, contribute to water insecurity by placing added strain on water systems and resources in settlement locations, thereby fuelling social tensions. A study conducted in Somalia indicates a 200% increase in gender-based violence against a group of displaced people.

An urgent need for transboundary agreements

This water scarcity can increase the risk of conflict. In the Sahel region, wetland degradation – often due to ill-advised water development projects – has exacerbated local disputes over access to water and productive land, causing tensions.

While approximately 40% of the world’s population lives in transboundary river and lake basins, only a fifth of countries have cross border agreements to jointly manage these shared resources equitably. Many transboundary basins are already located in areas marked by current or past interstate tensions. In the Arab region, seven countries were in conflict in 2021 – some dating back many years –which has had wide-ranging implications for water supply, infrastructure, and potential cooperation on water-related issues.

Africa remains especially vulnerable to interstate tensions relating to water: 19 out of 22 states studied suffer from water scarcity, and two-thirds of the continent’s freshwater resources are transboundary. Of the 106 transboundary aquifers mapped in Africa, interstate cooperation has only been formalized in seven.

Concrete progress in cooperation in several regions

In this context, cooperation on transboundary water management appears to be a powerful lever for maintaining peace. By creating conditions for regular dialogue between all parties and instituting the necessary legal frameworks, this cooperation has the potential to resolve most disputes relating to water, and therefore prevent the emergence or exacerbation of wider-ranging conflicts.

The Framework Agreement on the Sava River Basin (FASRB), signed in 2002 by Bosnia and Herzegovina, Croatia, Serbia and Slovenia, was the first multilateral, development-oriented agreement in South-East Europe. It has successfully laid the groundwork for sustainable water management. Two decades after its adoption, it has become a key driver of stability in the region, and now serves as an example of best practice for other regions of the world.

The decline in volume of Lake Chad – which has decreased in size by 90% over 60 years – has led to a broad range of economic and security challenges in the region. Yet in recent years, Cameroon, Chad, the Central Africa Republic, Libya, Niger and Nigeria have given a new impetus to the Lake Chad Basin Commission (LCBC). LCBC’s mandate has expanded to ensure the most efficient use of the basin’s waters, coordinate local development, and prevent the emergence of disputes that might arise among these countries and local communities. LCBC is today the most appropriate institution for addressing the specific needs of the basin, including socio-economic development and security issues.

These two examples highlight the fact that, even in complex situations, states have the means to enact policies around access to water and shared resource management that are both fair and equitable thanks to international cooperation and the support of the United Nations system.

The United Nations World Water Development Report is published by UNESCO on behalf of UN-Water and its production is coordinated by the UNESCO World Water Assessment Programme. The report gives insight into the main trends concerning the state, use and management of freshwater and sanitation, based on work by Members and Partners of UN-Water. Launched in conjunction with World Water Day, the report provides decision-makers with knowledge and tools to formulate and implement sustainable water policies. It also offers best practice examples and in-depth analyses to stimulate ideas and actions for better stewardship in the water sector and beyond.

Drinking Water Sources and Storage ENVR 890-2 Mark D. Sobsey Spring, 2009

WHO Risk-based Framework

Water Sources and Water Treatment • Drinking water should be essentially free of disease-causing microbes, but often this is not the case. • A large proportion of the world’s population drinks microbially contaminated water, especially in developing countries • Using the best possible source of water for potable water supply and protecting it from microbial and chemical contamination is the goal • In many places an adequate supply of pristine water or water that can be protected from contamination is not available • The burden of providing microbially safe drinking water supplies from contaminated natural waters rests upon water treatment processes • The efficiency of removal or inactivation of enteric microbes and other pathogenic microbes in specific water treatment processes has been determined for some microbes but not others. • The ability of water treatment processes and systems to reduce waterborne disease has been determined in epidemiological studies

Source Water Protection: Water Resources Management • Integral to the preventive management of drinking-water quality. • Preventing microbial and chemical contamination of source water is the first barrier against drinking-water contamination of public health concern. • Water resource management and potentially polluting human activity in catchments and aquifers influence water quality. • This impacts treatment steps required to ensure safe water • Preventive action may be preferable to upgrading treatment.

Influence of Land Use on Water Quality • Assess land use influence on water quality • Not normally undertaken by health authorities or drinking-water supply agencies alone • Establish close collaboration between public health authority, water supplier and resource management agency • may include other sectors, .e.g., agriculture, traffic, tourism or urban development. • National authorities must interact with other sectors to formulate national policy for integrated water resource management • Set up regional and local structures to implement policy • National authorities need to guide regional and local authorities by providing tools

Land Uses to Consider that Influence Water Quality • land cover modification • extraction activities • construction/modification of waterways • application of fertilizers, herbicides, pesticides and other chemicals • livestock density and application of manure • road construction, maintenance and use • various forms of recreation • urban or rural residential development • Pay particular attention to excreta disposal, sanitation, landfill and waste disposal • other potentially polluting human activities, such as industry, military sites,

Drinking Water Sources • Ground Water • Surface water • Rainwater • Condensed water from the atmosphere • Reclaimed wastewater • Other?

Groundwater • Water table or surficial aquifer • First water encountered through the soil or subsurface • Often subject to contamination from the land surface • Confined aquifer • Water found below a confining subsurface later of clay, rock or other impervious material • Often protected from contamination lan surface • Both may contain geological chemical contaminants • Arsenic and fluoride are probably of most health risk • Confined aquifer water is often better protected from surface contamination

Surface Waters • Lakes, ponds and other and “confined” bodies of water • Rivers, streams, creeks and other flowing bodies of water • All are subject to direct contamination from wastewater and excreta discharges • All are subject to contamination from land runoff • Surface water should be assumed to be contaminated unless proven otherwise by direct and indirect evidence from observations and analysis

Rainwater • Rainwater as it falls from the sky is essentially free of pathogens and toxic chemicals • Airborne contaminants can cause low level contamination with microbes and chemicals • Rainwater is collected primarily on roofs or other impervious collectors • Contamination from roof/impervious surface chemicals and microbes is possible • Rainwater is often stored in barrels, cisterns and other surface and sub-surface collectors or impoundments • Contamination is very likely unless special precautions are taken to protect the collected water from fecal and other sources of contamination

Condensed water from the atmosphere • Atmospheric water as clouds, fod and airborne mist can be harvested at it impacts impervious surfaces. • Solar Stills • Water evaporated from standing water also can be condensed and harvested • Solar condensers collect evaporated water • Solar energy can supply heat

Reclaimed Water • Water can be purified from sewage and other wastewater • Reuse for non-potable purposes in encouraged • Reuse for potable purposes is discouraged • Indirect reuse is considered feasible and of less risk by recharging aquifers or reservoirs and allowing addition die-off and further treatment • WHO and countries have regulations for non-potable and potable reuse

Water Treatment Processes: Storage Reservoirs, aquifers & other systems: • store water • protect it from contamination • Factors influencing microbe reductions (site-specific) • detention time • temperature • microbial activity • water quality: particulates, dissolved solids, salinity • sunlight • sedimentation • land use • precipitation • runoff or infiltration

Larger Scale Water Storage • Reservoir impoundments and other water storage diversions • Tanks and other fabricated vessels • Above and below ground cisterns, reservoirs and tanks

Household Water Containers for Safe Storage: • Material: Depends on Rx; easy to clean; lightweight, durable, impact- and oxidation- resistant, heat-resistant (if thermal Rx) • High-density polyethylene (HDPE) for chemical Rx • Transparent beverage bottles for solar-UV + heat (PET) • Black or opaque for solar-heat only • Can adapt traditional vessels to safer storage • Add cover • Add spout or spigot

Characteristics of Preferred HH Water Storage Vessels • Appropriate material, size, shape, dimensions, • Depends on collection, Rx method, use conditions & user • Volume: usually 10 and 30 liters (not too heavy) • smaller volumes (1-1.5 L) for solar Rx; multiples • Handles to facilitate lifting and carrying • Stable base to prevent overturning • Uniform size for standard chemical dosing • Opening: large enough to fill and clean; small enough to discourage hands, cups or other dip utensils. • Inlet: fitted with a lid • Durable spigot or spout for pouring

Household Water Containers for Safe Storage Plastic vessels are commonly used – many have safe features Traditional vessels, such as pots, urns and bowls can be made safe by covering and providing a dispenser (spigot or spout)

Household Water Storage: Disease Risks and Containers for Improved Protection • Inadequate storage results in microbial contamination and waterborne disease • Improved storage vessels reduce microbial contamination and disease risks • Improved storage can be coupled with household treatment to further improve microbial quality and reduce disease risks • Best implemented and sustained if supported with behavior modification, education, motivation and social marketing

Increased Microbial Contamination (Decreased Microbial Quality) and Infectious Disease Risks from Inadequately Stored Household Water

Reservoir Water Storage and Microbial Reductions • Microbe levels reduced over time by natural antimicrobial processes and microbial death/die-off • Human enteric viruses in surface water reduced 400-1,000-fold when stored 6‑7 months (The Netherlands) • Indicator bacteria reductions were less extensive, probably due to recontamination by waterfowl. • Protozoan cyst reductions (log10) by storage were 1.6 for Cryptosporidium and 1.9 for Giardia after about 5 months (The Netherlands; G.J Medema, Ph.D. diss.) • Recent US EPA ICR data indicates lower protozoan levels in reservoir or lake sources than in river sources; suggests declines in Giardia & Cryptosporidium by storage
