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...

Coastal wetlands, and salt marshes specifically, are simultaneously geomorphic and biologic systems. They proliferate across a narrow range of elevation, water level, and salinity conditions. Salt marshes rely on their own growth and sediment input to maintain or increase their extent, whereas physical forces such as waves and sea-level rise tend to reduce it.

Birds bring joy merely by their presence, from their bold colors and majestic songs to their grace as they glide through the sky. Birds contribute more than beauty to the environment and society. Many plants depend on hummingbirds and other species to pollinate them. Hawks and owls prey on rodents and other pests. Fruit- and grain-eating birds help spread plants’ seeds.
