What is the water quality?
water quality in the United States is highly regulated and includes strict water quality and water quality testing. As a result, drinking water in the United States is one of the safest drinks in the world. Although the water quality in the United States is high, there are still some basic problems. Therefore, both local and federal governments are constantly working to ensure that everyone in the community has safe drinking water.
Drinking water comes from two main sources. Surface water, such as lakes, rivers and tanks, provides a large part of the water used as drinking water. The groundwater, which is pumped from wells, is also a source of drinking water commonly used in rural areas.
surface water usually requires both filtration and disinfection to achieve drinking water quality standards. Groundwater is considered to be the cleanest source of water. This is because it is naturally filtered when it passes through layers of rocks and sediment in Aquifer. Today the Environmental Protection Agency (EPA) and STandards of water quality ensure that groundwater is subject to technological treatment. Most water systems add chlorine or other disinfectants to clean the water in the water distribution system and ensure the highest water quality.
Suppliers of local communities, such as cities, are also obliged to provide their customers an annual water quality report. They do it, so the consumer can be a "tracking dog" in terms of the safety level of their drinking water. Reports provide information about local drinking water, including a source of water and contaminants found in the water.
According to EPA, water quality standards are the basis of a water -based control program ordered by the Pure Water Act. The water quality standard consists of four basic elements. It first indicates the use of the water body. It also creates water quality criteria for protection of determined use. Thirdly, it sets out the policy of antidegradationTo maintain and protect existing uses and high quality waters. Finally, it determines the general principles that deal with implementation problems.
