What Causes Contaminated Water on Long Island
Contaminated water on Long Island is primarily driven by aging infrastructure, septic systems, and industrial or agricultural runoff. Volatile organic compounds, nitrates, and bacteria can enter private wells and public supplies. The region’s geology and high water table can increase exposure risks.
Health Risks and Common Contaminants
Common contaminants include coliform bacteria, nitrates, lead, and VOCs such as trichloroethylene. Short-term exposure can cause gastrointestinal illness, while long-term exposure may affect liver, kidney, or nervous system health. Infants, pregnant women, and immunocompromised individuals face higher risks.
Testing, Treatment, and Remediation Options
Residents can test well water through state-certified laboratories and public health departments. Treatment options include filtration, ultraviolet disinfection, and reverse osmosis.
