The American Journal of Clinical Nutrition recommends drinking up to 3 liters of fluid a day. Water is vital for all cell function.

The EPA has proposed “regulatory determinations” for two chemicals whose presence in drinking water has raised alarm among the public and health experts. The agency is proposing to regulate two contaminants perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) – but not six others: 1,1-dichloroethane, acetochlor, methyl bromide, metolachlor, nitrobenzene, and RDX.

In the early 1900s, a young dentist named Frederick McKay moved to a Colorado town where the residents’ teeth — though in some cases stained chocolate brown — had far less decay than was typical back then. He and other researchers eventually linked the phenomenon to fluoride in the town’s drinking water – a eureka moment that would usher in what is often called one of the 10 great public health achievements of the 20th century.

As part of the Obama Administration’s commitment to strengthen America’s climate resilience, the U.S. Environmental Protection Agency (EPA) has released an updated online climate change risk assessment tool that assists users in designing adaptation plans based on the types of threats confronting their communities.

The Centers for Disease Control and Prevention (CDC) has unveiled an addition to its EHS website: resources organized by essential services.
