Importance of Water Quality and Testing | Public Water

Water QualityWater TestingConsumer Confidence ReportsThe United States has one of the safest water supplies in the world. If you are among the 286 million Americans that get their water from a community water system (1), your tap water is regulated by the United States Environmental Protection Agency (EPA). Drinking water varies from place to place, depending on the condition of the source water from which it is drawn and the treatment it receives, but it must meet EPA regulations. Even though our tap water supplies are considered to be one of the safest in the world, water contamination can still occur. There are many sources of contamination, including: 1. Sewage releases 2. Naturally occurring chemicals and minerals (for example, arsenic, radon, uranium) 3. Local land use practices (for example, fertilizers, pesticides, livestock, concentrated feeding operations) 4.

The History of Clean Drinking Water | APEC Water

HistoryEarly historyOriginBackgroundHealthClean drinking water is so widely available today that many people take it for granted. In actuality, human beings have taken extensive measures throughout history to produce clean drinking water, and such efforts even date back to before they discovered how to make fire by rubbing two sticks together. In the ancient times, people determined the purity of water by taste, and this method has been found to be incorrect later on. Nonetheless, their continual efforts in obtaining clean drinking water have led to the development of many innovations that make water treatment more successful today.
