Groundwater in Lunenburg County contains chloride, E. coli, and fecal coliform bacteria. Contaminant levels here are low and do not exceed EPA health standards.
Chloride and bacteria enter groundwater through septic systems and surface runoff when rainfall or snowmelt carries them downward through soil into wells. The crystalline rock beneath this county is hard and does not dissolve easily, which limits how much mineral contamination develops. Wells drilled into deeper parts of this rock stay cleaner than shallow wells because the rock filters out more bacteria and contaminants before water reaches them.
Groundwater in this county is soft, with low concentrations of dissolved minerals like calcium and magnesium. The crystalline rock here does not break down readily to release the minerals that make water hard. Most wells in Lunenburg County show this soft-water character.
Wells in Lunenburg County show bacteria contamination including E. coli and fecal coliform. These germs come from human and animal waste and can make you very sick. Exposure to contaminated water causes serious intestinal illness, severe diarrhea, and dangerous infections that require medical care. Children, elderly people, and anyone with a weak immune system face extra risk from bacterial contamination.
The mineral content in county wells is generally low, so staining and scale buildup from hard water are not a major concern here. Water quality in this county should not damage your appliances or create unpleasant tastes and odors from mineral buildup.
Your well is different from others in the county, so testing is the only way to know what is actually in your water. Because bacteria and chloride are concerns here, we recommend a comprehensive water panel that checks for bacteria, nitrate, and minerals. Testing typically costs between $200 and $400. Once you know your results, treatment options like chlorination systems or bacterial removal filters can protect your family's health.

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.
