The River Alert Information Network (RAIN) is a voluntary, collaborative, proactive effort amongst public water supply systems in western Pennsylvania and northern West Virginia to protect public health by ensuring a safe and reliable source of drinking water.
- RAIN member systems all share a common trait; they all rely upon river water as their source of water.
- RAIN watershed basins include the Allegheny River Basin, Monongahela River Basin, Beaver River Basin and the first 36 river miles of the Ohio River.
- These rivers are used as drinking water sources within these basins include: the Ohio, Allegheny, Monongahela, West Fork, Tygart Valley, Buckhannon, Cheat, Youghiogheny, Beaver and Shenango. RAIN monitoring sites monitor for pH and specific conductance.
- RAIN uses specific conductance in order to approximate the amount of TDS in the river.
- Some RAIN sites currently monitor for additional water quality parameters, such as turbidity and/or dissolved oxygen.
- RAIN plans to expand the water quality parameters for which it monitors, such as organics, bromide, oil and diesel.

RAIN’s new interactive map uniquely represents how and where RAIN monitors the rivers from which most of the region’s drinking water is taken.
It allows you to see the water data collected, and helps inform you of general water quality data you need to know about the water resources used by public drinking water systems.
Current river data displayed for pH, conductivity, temperature and other parameters is collected from various sites along the Allegheny, Monongahela, Ohio, Youghiogheny, Shenango, and Beaver rivers. The Current River Data displayed is provided to make it easier for you to get current river information in near real-time from one central location. As such, please be aware that the data presented on this public interactive map for the RAIN sites is provisional, and is being supplied as it is collected for educational use.
In addition, the map also provides overlay tools (Watersheds, Rivers, USGS sites, Land Ownership, and more) that help put into context the data provided at each of the RAIN monitoring locations. Many of the overlays provide additional links to pertinent sites maintained by the USEPA and/or USGS, so you can easily drill down to associated data for a given geographical locale.
