Practical pathways for protecting headwater streams in urbanizing areas Practical pathways for protecting headwater streams in urbanizing areas
Headwater streams are diverse ecosystems and important sources of water and dissolved and particulate resources to the downstream river network. However, across the world, they are rapidly being degraded or lost through human activities, particularly urban development. This degradation and loss have negative consequences for the structure and function of headwater streams, as well as...
Statistical streamflow comparison of current and historical 30-year periods for selected streams in New Jersey Statistical streamflow comparison of current and historical 30-year periods for selected streams in New Jersey
As the population of New Jersey increases, supplying adequate drinking water to meet demand remains a high priority. To better understand potential streamflow trends over time, the U.S. Geological Survey completed a study comparing low flows at continuous- and partial-record streamgages in New Jersey between a historical period (1950–79) and a current period (1990–2019). Fourteen...
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...

Evaluating the Risks of Tire-Derived Compounds to Fish in the Chesapeake Bay Watershed
Tires contain a chemical known as 6PPD which prevents them from quickly breaking down. Microscopic tire particles, generated mainly from the friction of tires on roads, release 6PPD-quinone (6PPDQ) when they come into contact with oxygen. During precipitation events, 6PPDQ can be washed off roads, harming fish in nearby waterways. In response to requests from fishery managers, the USGS is studying...
Water Levels in the Ten Major Confined Aquifers of the New Jersey Coastal Plain
The Coastal Plain aquifers of New Jersey provide an important source of water for more than 3.5 million people. The USGS, in cooperation with the New Jersey Department of Environmental Protection, has been measuring water levels in the confined aquifers of the New Jersey Coastal Plain every five years beginning in 1978. Persistent, regionally extensive cones of depression are present in Ocean and...
