This geonarrative describes the stream biological monitoring conducted as part of the Chester County - U.S. Geological Survey Cooperative Water Resources Program.

This geonarrative explains and explores the results of more than 20 years of sampling. Methods for sampling and pesticide use in Pennsylvania are also described. 

The Philadelphia Water Department (PWD) and USGS have been working together to create and expand the water-quality monitoring network for Philadelphia. Data from these gaging stations will allow PWD scientists and engineers to monitor spatial and temporal water quality/quantity trends in support of watershed restoration initiatives occurring in Philadelphia. 

This geonarrative describes the sediment and turbidity monitoring conducted as part of the Chester County - U.S. Geological Survey Cooperative Water Resources Program.

The Pennsylvania Drought Condition Web Tool shows the current drought status for each county and hydrologic conditions for precipitation, streamflow, groundwater levels, and Palmer Drought Index used by PADEP for drought monitoring.

This geonarrative is an interactive online presentation of the USGS Pennsylvania Water Science Center's data collection efforts related to Hurricane Ida. This geonarrative includes a summary of the storm in Pennsylvania, USGS data collection methods, embedded interactive maps of flood extents in 5 southeastern Pennsylvania localities, and visual depictions of the storm’s impact across the state.

USGS is helping identify potential locations in Pennsylvania where additional or updated water-level data may be needed during or after major storm events. Pre-identification of these locations supports expedited decision-making for site selection, resulting in safer and more timely installation of flood monitoring instruments.

Pennsylvania Groundwater Watch provides access to groundwater level data from 108 sites in the USGS Active Groundwater Level Network for Adams, Chester, Montgomery, Philadelphia, and Pike Counties. 

Since 1969, the Pennsylvania Water Science Center has had a cooperative program with Chester County to measure and describe water resources. Cooperation has been primarily with the Chester County Water Resources Authority, with participation from the Chester County Health Department.

The Chester County Monitoring Network web tool provides near real-time water data. 

USGS Pennsylvania Water Science Center, in cooperation with the Pennsylvania Department of Environmental Protection, samples 28 wells biannually to monitor ambient groundwater quality conditions in a variety of settings throughout Pennsylvania. The most recent results for selected constituents can be accessed through the Groundwater Quality Monitoring Network Data Exploration Tool.

Radon, a colorless and odorless gas, is commonly found in groundwater in Pennsylvania. This web tool allows interactive display of Pennsylvania Water Science Center measurements of radon in groundwater samples from wells. All data presented here is publicly available and a data download tool is provided that will output all currently-displayed data. 

Real-time computed concentrations of water-quality constituents such as suspended sediment and fecal coliform bacteria are calculated using ordinary least squares regression models. The results of these models, along with direct water-quality measurements, can be viewed here as time-series graphs, or downloaded as tabular data.
