RAIN's Role

RAIN's network includes a handful of drinking water suppliers in western Pennsylvania and northern West Virginia. These water suppliers draw our drinking water from the sources RAIN monitors: the Allegheny, Monongahela, Ohio and their tributary rivers: West Fork, Buckhannon, Cheat, Youghiogheny, Beaver and Shenango. 

Drinking water suppliers have a vested interest in the quality of the source water they treat. The cleaner the source water, the easier it is to treat, the lower the expense of treatment. That means the higher the quality of water ultimately made available for drinking is good for everyone. RAIN provides the information for those water supplier systems to see the quality of the water they are intaking for treatment. RAIN also provides this information for the public on our interactive map to inform the community about the status of their rivers and ultimately their drinking water.


Public drinking water supplies in the United States are amongst the safest in the world, even as drinking water sources are subject to contamination and require appropriate treatment to remove disease-causing agents.

RAIN members—drinking water facilities utilizing our major rivers as their source water—diligently treat the source water using various methods of water treatment in order to provide safe drinking water for their communities.

In a voluntary effort to be more proactive in their efforts, RAIN members have developed an early warning spill detection system to detect and alert communities to sudden changes in river water quality. This warning system provides RAIN members with valuable knowledge, AND the time to make necessary decisions regarding water treatment and/or other system operations in order to ensure their communities continue to receive safe drinking water.

RAIN also collaborates with its public and private partners to develop more comprehensive initiatives for source water protection. RAIN’s partner and fiduciary agent, Penn’s Corner Conservancy Charitable Trust, is a nonprofit conservation organization that has a 35 year legacy of coordinating the financial and technical resources to identify source water and watershed management problems, establish goals and objectives, build strategies, and implement plans.
