Pollutants enter the water by:
* Direct discharge from sewers from municipalities, industries and farms * By runoff (indirect discharge) from sewers from Golf courses, municipalities, industries and farms * Purposeful dumping of waste and sewage * Spills and leaks from ships, trains, trucks and pipelines * By adsorption from the air * By being washed out of the air by precipitation * By leaching from the soil by water and acid rain
What else can I help you with?
Why must the water supply be protected from pollutants?
For health and welfare of the earth and its inhabitants.
Pollutants contaminate the water supply. is this true or false?
true - they have undesirable effects
What is the purpose of a water backflow valve and how does it prevent contamination of the water supply?
A water backflow valve prevents contaminated water from flowing back into the clean water supply. It does this by only allowing water to flow in one direction, preventing any backflow of potentially harmful substances or pollutants.
What is the purpose of an irrigation backflow preventer valve and how does it help in maintaining the safety and integrity of the water supply system?
An irrigation backflow preventer valve is used to prevent contaminated water from flowing back into the clean water supply system. It helps maintain the safety and integrity of the water supply by ensuring that water flows in one direction only, preventing the risk of contamination from pesticides, fertilizers, or other pollutants entering the water supply.
What is System separator for tap water connection?
A system separator for tap water connection is a device that is installed in a tap water system to prevent any contaminated water from flowing back into the main water supply. It helps to maintain the integrity and safety of the overall water supply by ensuring that no pollutants or chemicals can enter the public water system.
Can oil affect raindrops?
Effects of Oil on RaindropsYes, oil can affect raindrops. Pollutants from the oil, as well as gases and pollutants from the dispersant can be carried by raindrops.
What effects can weathering and erosion have on the water supply?
Weathering and erosion (which are synonyms) can cause minerals to leach into the water supply - for example, erosion of a rock which contains bauxite will cause aluminum to be present in the downstream water.
When water evaporates and condensates does it still contain pollutants?
YES BECAUSE some pollutants are evaporated with water
How does drinking water become consumable?
Drinking water becomes a consumable resource if it is in short supply such as in drought times or if the supply has become contaminated. This would therefore mean that this resource could not be replaced unless a process is carried out.
What is dispersing pollutants in larger volumes of water referred to as?
Dispersing pollutants in larger volumes of water is called dilution.
What is the purpose of an irrigation back flow valve and how does it help prevent contamination of the water supply?
An irrigation backflow valve is used to prevent contaminated water from flowing back into the clean water supply. It works by allowing water to flow in one direction only, preventing any backflow of potentially harmful substances or pollutants. This helps maintain the safety and quality of the water supply by ensuring that only clean water is distributed for irrigation purposes.
Why the irrigation is carried out in water scarcity regions?
Irrigation is carried out in water scarcity regions to optimize water use efficiency and ensure a consistent water supply for agriculture. By maximizing the effectiveness of irrigation techniques, farmers can produce crops with less water, ultimately helping to alleviate pressure on limited water resources in these regions.
