Pittsburgh District’s Water Quality team conducts first “spring pulse”
Destinee Davis, a biologist with the U.S. Army Corps of Engineers Pittsburgh District’s Water Quality team, collects a water sample on a bridge in West Hickory, Pennsylvania, March 30, 2023. The district’s Water Quality team collected water samples from the Allegheny River both before and after the spring pulse to compare the pulse’s effect along various points on the river. The collected samples are sent to the Corps of Engineers Research and Development Center to test and analyze myriad factors such as pH acidity, alkalinity, metals, nutrients, and conductivity.
