5. Understanding Water Quality Trends

Regular testing allows you to monitor water quality trends over time. By keeping records of your test results, you can detect changes in water quality, identify potential contamination sources, and take preventive measures to protect your water supply.

Common Well Water Contaminants in Virginia

Virginia’s well water can be contaminated by a variety of sources, both natural and man-made. Here are some common contaminants that Virginia residents should be aware of:

Bacterial Contaminants

  • Coliform Bacteria: These bacteria are commonly found in the environment and are usually harmless. However, their presence in well water can indicate possible contamination by more harmful pathogens.
  • E. coli: A specific type of coliform bacteria that can cause severe gastrointestinal illness. E. coli contamination often comes from human or animal waste.

Chemical Contaminants

  • Nitrates: Commonly found in agricultural areas due to fertilizer runoff. High nitrate levels can be dangerous for infants and pregnant women.
  • Pesticides and Herbicides: These chemicals can leach into groundwater from agricultural activities and can have various health effects, including cancer and reproductive issues.

Heavy Metals

  • Lead: Can enter well water through corroded pipes or plumbing fixtures. Lead exposure is particularly harmful to children, causing developmental issues and neurological damage.
  • Arsenic: Occurs naturally in some Virginia soils and can contaminate groundwater. Long-term exposure to arsenic can lead to cancer and other serious health problems.

Natural Contaminants

  • Radon: A naturally occurring radioactive gas that can dissolve into groundwater. Radon exposure can increase the risk of lung cancer.
  • Iron and Manganese: These minerals are common in Virginia’s groundwater and can cause staining of fixtures and laundry. While not typically harmful to health, high levels can affect water taste and appearance.
