One thing the Obama family may not like about Washington, D.C., is the water, which has trace amounts of weed killer, gasoline additives, and industrial chemicals. All these pollutants are found in the Potomac River, the source of most drinking water in D.C.
But the problem extends far beyond the Potomac. Some 200 million Americans have measurable levels of agricultural or industrial chemicals in their water supplies. Water companies use advanced filters, UV light, and other treatments to kill harmful bacteria and reduce contaminants. But to truly clean up our water would require curbing runoff from agricultural waste and banning industries from pumping pollutants into rivers.

We believe in America's ability to innovate and solve big problems. We've proven time and time again we can rise to the occasion and address major environmental challenges without harming the economy. Just think about the Clean Water Act and the Clean Air Act. Global warming and dirty energy put America's water resources at risk – now is the time to act!
