Potentiometric surface maps and groundwater-level hydrographs for confined aquifers of the New Jersey Coastal Plain, 2018 Potentiometric surface maps and groundwater-level hydrographs for confined aquifers of the New Jersey Coastal Plain, 2018
The U.S. Geological Survey, in cooperation with the New Jersey Department of Environmental Protection (NJDEP), prepared potentiometric surface maps for 10 confined aquifers of the New Jersey Coastal Plain physiographic province based on water-level measurements collected during late 2018 and early 2019 from 951 wells in New Jersey and parts of Pennsylvania and Delaware. Maps were...
Estimating daily public supply water use by drinking water service area in New Jersey Estimating daily public supply water use by drinking water service area in New Jersey
This report, prepared in cooperation with the New Jersey Department of Environmental Protection, presents a method for estimating daily public supply water use by drinking water service area systems for New Jersey. The ability to accurately estimate daily public supply water use could help water supply planners in New Jersey better understand and manage the state’s limited water...
Time of travel of releases from Lake Wallenpaupack to the U.S. Geological Survey’s streamgage monitoring location on the Delaware River at Montague, New Jersey Time of travel of releases from Lake Wallenpaupack to the U.S. Geological Survey’s streamgage monitoring location on the Delaware River at Montague, New Jersey
In 2016, the U.S. Geological Survey (USGS) carried out a hydraulic study within the upper Delaware River Basin for the purpose of determining the time of travel for water releases from the Brookfield Renewable U.S. hydroelectric plant at Lake Wallenpaupack, Pennsylvania, to reach the USGS streamgage located on the Delaware River at Montague, New Jersey (site number 01438500). From...

A regional assessment of fish health in the Chesapeake Bay watershed
Fish diseases in freshwater ecosystems pose significant ecological and socioeconomic challenges; yet, monitoring them in wild populations is complex due to interactions between pathogens, hosts, and environmental conditions. External DELT (deformity, erosion, lesion, tumor, and parasite) data (fig. 1) provide a rapid and broad measure of fish health but are a relatively coarse indicator that...
City of Elizabeth Flood Mapping
To better protect the City of Elizabeth’s residents and assets, the U.S. Geological Survey (USGS) and Rutgers University proposed a joint collaboration to develop a reliable flood risk management platform with the cooperation of the City of Elizabeth and the New Jersey Office of Emergency Management. Our understanding is the broader goal for the City of Elizabeth is to accomplish three primary...
