Targeted Studies

In addition to routine water quality monitoring in the Ohio River Basin, 3RQ’s “Targeted Studies” provide the ability for researchers to immediately respond to citizen concerns, develop focused studies, and expand monitoring to parameters other than TDS. As gas exploration and other water quality threats increase throughout the Mon Basin, water quality changes can be monitored through targeted studies to provide a fast response when a potential issue arises. Learn more about several 3RQ Targeted Studies below.


Monongahela: Trihalomethanes

Trihalomethanes (THMs), a family of halogenated disinfection byproducts, are ubiquitously present in finished drinking water. They form as a result of the interaction between organic matter and chlorination in the disinfection process. 3RQ has partnered with several water authorities in Southwestern Pennsylvania to study levels of THMs and conditions that affect their formation.

Monongahela: Tenmile Creek

April 2014 testing results showed alarming levels of radium in discharges to Tenmile Creek from the abandoned Clyde Mine and coal refuse piles further upstream near Waynesburg and at the Cumberland Mine on Whiteley Creek. In response,  3RQ performed a targeted study to help provide reliable information to the communities surrounding Tenmile Creek who were concerned about the quality of their streams and their health.

Ohio: Captina Creek

After years of 3RQ monitoring, trends of rising bromide and total dissolved solids (TDS) have been observed in Captina Creek, a tributary to the Ohio River near the town of Armstrong Mills, OH. By analyzing monthly data from 2012 through the present, we learn more about these trends as we continue to monitor this site in the future.
