All believe that drinking water in the USA is high quality. The U.S. Environmental Protection Agency (EPA) is very cautious about this and maintain regular monitoring and reporting. This agency sets standards for water quality and enforce to keep to ensure public health safety and limits the levels microorganism and chemical contaminants those cause various disease. However there are stringent water regulations, but concerns regarding water quality and decontamination still present across the nation. To address this aspect, we should think about our household level faucet water filter despite outside water treatment system by the suppliers.
Several scientific studies and data on water quality show that there is reasonable numbers of contaminants are present in USA water. If you consider drinking tap water, there are 316 contaminants, according to research from the Environmental Working Group. From these study findings (3-year investigation), it shows that US citizens have good reasons to worry about the safety of the drinking water that flows from their taps. Since 2004, EWG had assembled, and unique database of 20 million drinking water quality tests covered 48,000 communities in 45 states of USA. One of the reasons is that drinking water regulation applied at the water production or treatment sites. Once the water flows in different supply channels e.g. reservoirs, pipes, water tank, it may become re-contaminated before consumers. Some of the causes are – natural occurrence; point and non-point sources of pollution; leaching or corrosion of materials in the distribution systems e.g. metal, chemicals from pipe and fittings.
