Monitoring Data at Willow Grove and Warminster

Streamflow and stage monitoring data near former Navy Bases at Willow Grove and Warminster, Pennsylvania

Streamflow Monitoring

USGS provides streamflow information in the study area that can be used in conjunction with water quality data to evaluate the mass of contaminants transported by streams and the relations between concentrations and flow conditions. Other applications may include evaluating groundwater/surface water interactions and transient effects of point discharges from wastewater treatment plants.
