Virginia Tech’s recent discovery of abnormally high amounts of lead in the Flint, Michigan, water system has made safe drinking water a hot topic. But while the water in Flint came from a municipal source, private water systems, such as wells, springs, and cisterns, are not immune to this problem.
Testing conducted though Virginia Cooperative Extension’s Virginia Household Water Quality Program has found high levels of lead in private systems around the state.
Kelsey Pieper, a researcher on the Flint team who received her doctorate from Virginia Tech, was the primary author on the study that found 1 in 5 private systems had lead concentrations above the Environmental Protection Agency standard for municipal systems. About 45 percent of the samples contained coliform bacteria and 10 percent contained E. coli.
