According to GroundWater.org, more than half of the U.S. depends on groundwater, which can be used for municipal water and as the source of water for people with private wells.
Groundwater is an important resource, but it can become easily contaminated and polluted. As the experts at The Groundwater Foundation explain …
“Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use. Materials from the land’s surface can move through the soil and end up in the groundwater.”
Those materials also include pesticides, fertilizer, and other agricultural runoff like manure, as well as toxic material from hazardous waste sites and leaky landfills.
