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...

New England Drought Information

Droughts are among the most costly hydrologic hazards in the United States. They are generally slow in developing, frequently occur over a long period of time, and can affect large areas and populations. The severity of a hydrologic drought is not always obvious until these water supplies are seriously depleted.
