Water Quality Testing
Clarity for Complex Homes — Know What’s in Your Water
Water quality testing provides objective information about your drinking water through proper sampling and third-party laboratory analysis. Whether you’re on a private well or municipal supply, testing can help identify concerns related to taste/odor, staining, corrosion, health-related indicators, or general baseline screening—so you can make informed decisions about filtration, treatment, or next steps.
Based in Southampton, NY, we provide water quality testing across the East End of Long Island, including Bridgehampton, Sag Harbor, Water Mill, East Hampton, and surrounding areas.

Important Notes
Water quality testing reflects the sample collected at the time of sampling. Conditions can change with seasonality, usage patterns, plumbing work, and well performance. We do not provide medical advice; testing is intended to inform decisions about water treatment and maintenance.
What We Test For
Testing is selected based on your goals and the water source. Common options include:
Basic Screening (Common Starting Point)
General water chemistry indicators (e.g., hardness, pH, minerals)
Indicators associated with staining, scaling, or corrosion potential
General bacterial screening (often recommended for wells)
Targeted Testing (When Appropriate)
Nitrate/nitrite (common well concern)
Lead and copper (often driven by plumbing and fixtures)
Iron and manganese (staining/taste/odor contributors)
Volatile Organic Compounds (VOCs) and other targeted analytes (as needed)
We’ll recommend a sensible testing panel based on the property type, water source, and the concern you’re trying to answer.
Common Times to Test
During a pre-purchase inspection (especially for wells)
After a home has been vacant/seasonal
After plumbing work, fixture upgrades, or filtration changes
When taste/odor or staining changes appear
As a periodic check for well systems
