Groundwater Recharge - Pennsylvania
New baseflow and recharge estimates were published in a USGS data release in 2023 (see 'Data' tab). Recharge is the process of adding water to the saturated zone. Because it is almost impossible to measure directly, recharge is usually estimated by indirect means. Completed USGS studies provide estimates of groundwater recharge in Pennsylvania and methods for estimating recharge in humid regions.
Groundwater Quality of Domestic Supply Wells in Pennsylvania
Most rural residents in Pennsylvania use groundwater from domestic supply wells for drinking, cleaning and other purposes. Some groundwater samples have been analyzed for private purposes, but those results generally are not readily available to the public. Many of the publicly available water-quality samples from rural areas were collected more than 30 years ago. Quality-assured groundwater...
Groundwater Use
Groundwater refers to all subsurface water, specifically that part of groundwater which is in the saturated zone. Groundwater sources are called aquifers: geologic formations that contain sufficient saturated permeable material to yield significant quantities of water to wells and springs. For the purposes of the USGS water-use reports, groundwater with less than 1,000 milligrams per liter (mg/L)...
Domestic Water Use
Domestic water use includes indoor and outdoor uses at residences, and includes uses such as drinking, food preparation, bathing, washing clothes and dishes, flushing toilets, watering lawns and gardens, and maintaining pools. Domestic water use includes potable and non-potable water provided to households by a public water supplier (domestic deliveries) and self-supplied water use. Self-supplied...
Domestic (Private) Supply Wells
More than 43 million people—about 15 percent of the U.S. population—rely on domestic (private) wells as their source of drinking water. The quality and safety of water from domestic wells are not regulated by the Federal Safe Drinking Water Act or, in most cases, by state laws. Instead, individual homeowners are responsible for maintaining their domestic well systems and for monitoring water...
Delaware River Basin Focus Area Study
As one of several National Focus Area Studies within the USGS National Water Census (NWC), the USGS completed a 3-year study of water availability and use in the Delaware River Basin.
