Realtors & Real Estate Professionals

Clean water is one of our most important resources.  Water from private wells does not go through the same regulatory protections as it does in public water systems.  Homeowners with private wells are responsible for ensuring their water supply is protected and safe to drink.  The EPA recommends that homeowner on private wells test their well annually to ensure the water is safe.  

In addition to testing your well for bacteria and nitrates annually, check with your local health department to determine if your area may be at higher risk of specific contaminants.

Well water is also prone to high levels of minerals which can cause aesthetic problems.  Chlorides and low pH cause corrosion problems.  Iron, manganese, and hardness cause problems like staining, noticeable taste, and scaling.
