This summer, we will be hosting a Pennsylvania Mountain Service Corps AmeriCorps, member-- Justin! Join us in welcoming Justin who will be serving as one of our PMSC Environmental Educators this summer!

My name is Justin and I am excited to join TRWK as an Environmental Educator! I graduated from the University of Pittsburgh with an Environmental Studies degree last year and this fall I will be pursuing a Master's of City Planning at Georgia Tech. Some of my environmental interests include (but are not limited to) conservation, environmental justice, pollution reduction, and urban heat. In my free time, I love to play tennis, go on hikes, watch movies, go to concerts, and explore the great city of Pittsburgh!

On May 26th, 2022, a Norfolk Southern train collided with a truck near Harmar Township, causing the derailment of 17 train cars containing petroleum distillates and plastic pellets. Nine cars ended up in the Allegheny River tributary-- Guys Run. For the past 4 years, Three Rivers Waterkeeper has monitored the site's remediation. Now, on the anniversary of the derailment, we are advocating for continued remediation and monitoring of the site.

Thank you to everyone who came out on Monday to help us count nurdles! These pre-production plastic pellets were collected along the Allegheny and Monongahela Rivers.

Last Thursday, we gathered at the Millvale Community Library to discuss E. Coli in Pittsburgh’s Rivers! We spent the evening discussing how E. coli affects our region’s waterways and delved into some of our data from the 2025 Swim Guide Season. It was great to connect with community members and share ways to get involved with our Swim Guide data!
