Why test private-well water?
Most island homes rely on private wells. Seasonal vacancy, heavy rain, coastal conditions, septic systems and aging plumbing can affect water quality without an obvious change in taste, smell or appearance.
Common sampling options
Basic potability & safety
- Total coliform bacteria
- E. coli
- Nitrate and nitrite
Broader private-well screening
- pH, hardness and alkalinity
- Chloride and sodium
- Turbidity and total dissolved solids
- Iron and manganese
Specialty panels
- Lead, copper, arsenic and other available metals
- PFAS panels
- Volatile organic compounds and fuel or solvent screens
- Radon in water when appropriate
- Hydrogen sulfide, tannins, salinity and corrosivity tests
Choose testing based on the property
The appropriate panel depends on the well, property use, prior results and specific concerns. Laboratory availability and recommendations may vary; contact us to discuss the sampling scope.
