ABSTRACT Private wells provide a source of household water for over 40 million people in the United States and an estimated 1 Coastal Lowlands Aquifer system along Gulf Mexico. Well quality is dependent on local geology factors that contribute to anthropogenic contamination from surface. Here, we evaluated groundwater well management southern Alabama, USA, better understand influence exposures through drinking private wells. The most common constituents exceeded USEPA primary or secondary human health benchmarks were pH (92%), total coliform (TC) (25%), followed by Fe (7%), Pb (6%), nitrate (1%), As (1%). Most (68%) also displayed temporal changes number exceedances, often showing positive TC during one sampling campaign negative another, while standard (6.5-8.5) was consistently not met. We found choices treatment did protect against exceedances. Our results underscore need coupled with practices when assessing potential population water.
