Three Rivers WaterKeeper Releases 2025 State Of Our Waters Report In Pittsburgh Area, Western PA

On July 22, the
Three Rivers WaterKeeper released the 2025 State Of Our Waters Report that includes year's worth of water quality testing, pollution identification, and stewardship of the three rivers and their tributaries in Pittsburgh and Western Pennsylvania.

During 2025, Three Rivers Waterkeeper spent 765 hours monitoring our waterways and took 476 water samples while analyzing 95 different water parameters across 78 different locations. 

They also launched our continuous monitoring buoy on the Beaver River from April 2025 to November 2025 - providing long-term trends.  These data are explored in their report.

"Our report delves into the different types of data we collect throughout the year. By looking at our waterways through the lens of different water quality parameters, we can see more about our region's waterways as a whole. Whether it's E.coli data, chloride data, PFAS data, or YSI data, our observations and data show that many of our creeks and streams are within healthy ranges, but some areas are particularly impacted by pollution, some of which is ongoing and some of which is legacy" explains Koa Reitz, Environmental Scientist at Three Rivers Waterkeeper.  

Three Rivers Waterkeeper’s most popular water testing is Swim Guide Monitoring

During 2025, Three Rivers Waterkeeper collected small snapshots of E. coli levels (unhealthy bacteria/sewage in the water) at 35 different sample sites collecting 235 samples over 21 weeks of testing. 

The total pass rate for all sites was 32% and 0 sites passed all 21 weeks. 

"One of the most common questions we get from community members is 'how healthy are our rivers?' We hope that by providing the community with data about the state of our rivers, people are able to make informed opinions about our waterways" said Jess Friss, Director of Community Programs at Three Rivers Waterkeeper. 

The report highlights the biodiversity of our region as well with a focus on a special project, “What’s living in our Waterways” where they surveyed 6 local tributaries to create a pocket field guide and ArcGIS storymap. They found over 100 species during their surveys, including Great Blue Herons, salamanders, water snakes, and toads! 

"Our region has such a history of extraction, degradation, and pollution, but our rivers and tributaries are resilient and can sustain diverse ecosystems, and our report highlights that" explained Koa Reitz
