The journey that water takes to your tap usually begins in the Potomac River, which is 383 miles long. Our river has an abundant supply of water, but it is also home to a few major types of pollutants that rush in during rain storms.

Chemical pollution: there are 80,000 chemicals in the US marketplace. Our government only tests our water for 1 out of every 400. Many of these chemicals are Endocrine Distruptors, a type of chemical pollution believed to be the cause of fish kills and intersex fish in the Potomac. Learn More >>

Nutrient pollution: nitrogen and phosphorus are entering our water in toxic amounts, spawning algae that leads to fish kills. Learn more >>

Sewer overflows: rainstorms can cause vast amounts of unprocessed human and industrial waste to spill into our water supply untreated. Learn more >>
