Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Groundwater Quality Monitoring Network

Overview

Pennsylvania’s Statewide Fixed Station Groundwater Quality Monitoring Network (GWMN) currently consists of a set of 27 groundwater wells located in 26 counties that are sampled twice a year for a host of chemical constituents. The GWMN was established to characterize the ambient groundwater quality of Pennsylvania aquifers and to provide a temporal dataset to address seasonal...

Bird Banding Laboratory

The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America.  This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...

Tidal Freshwater Ecosystems

This habitat system is characterized as tidally influenced freshwater systems, which provide critical habitat for many migratory (diadromous) fish species.  Characteristic species that inhabit this zone include mussels, sturgeon, shad, herring, alewife, American eel, striped bass, and perch.

Freshwater Mussel Physiology

Freshwater mussels are considered ecosystems engineers benefiting the streams and rivers they inhabit through filtration, biodeposition, and nutrient cycling, thereby influencing water quality.  However, many of these species are rapidly declining due to shifting environmental conditions and habitat loss.  Researchers at Leetown Science Center are evaluating how different species of mussels...
