Chloride, E. coli, and fecal coliform are present in groundwater in Lynchburg city. Contamination levels are low and do not exceed EPA health standards.
Chloride comes from road salt and urban runoff in developed areas. E. coli and fecal coliform indicate bacterial contamination from septic systems, wastewater pipes, or surface water seeping into shallow wells. The crystalline rock that makes up the aquifer here does not naturally filter bacteria as well as softer rock formations do, and urban land use increases the risk of contamination entering groundwater.
Groundwater in Lynchburg city is characterized by low sulfate levels. The crystalline rock beneath the city does not contain minerals that dissolve easily into water. This mineral profile is typical across wells in the area.
Wells in Lynchburg city do not show analytes exceeding EPA health standards at the county level. However, bacterial contamination including e. coli and fecal coliform bacteria have been detected in some wells in the area. These bacteria come from sources like septic systems or animal waste and can cause serious illness if consumed, especially for young children, elderly people, and those with weakened immune systems. Chloride has also been found in wells here at elevated levels.
Mineral content in Lynchburg city wells appears relatively low based on available data. Sulfate levels are low, which means you are less likely to experience problems like scale buildup in pipes and appliances or the metallic tastes that come with higher mineral content. Hard water problems are not a major concern for wells in this area.
Since bacterial contamination has been found in county wells, we recommend testing your well right away for bacteria and nitrate. Your well could have different contamination levels than what is common in the county, so testing is the only way to know what is actually in your water and what treatment you might need. A basic screening for bacteria costs between fifty and one hundred dollars. If bacteria is found, chlorination or ultraviolet light treatment can address it.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
* Microbial contaminants (E. coli, coliform) reflect only samples from the last 10 years.
