Maps
Maps are vital to displaying and disseminating our data and investigative findings. Our staff work on a diverse range of products built on a foundation of spatial data. We collect environmental data on the landscape and maps provide the geographic reference.
Many of our maps are published in USGS report series.

2012 SPARROW Models for the Northeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow
SPARROW model results of mean daily streamflow and average annual total nitrogen, total phosphorus and suspended sediment load in Northeast US streams. The simulated streamflow represents long-term average source inputs and hydrologic conditions from 1999 to 2014. The simulated loads represent source inputs similar to 2012 and normalized to long-term average hydrologic conditions from 1999 to 2014
Pennsylvania Groundwater Quality Monitoring Network
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.
