Turn concern into measurable information

Test for the concern you actually have

Lead, bacteria, PFAS, VOCs, metals and other contaminants require specific laboratory analysis rather than a generic 'water test.'

Drinking-water testing

Professional Drinking Water Testing for Homes, Businesses and Facilities

Water quality at the point of use is influenced by both the incoming supply and the property itself. Service lines, interior piping, valves, fixtures, storage equipment and building use can all affect the water after it leaves the public distribution system.

Olympian Water Testing provides professional drinking-water testing for homeowners, renters, property buyers, businesses, building owners and managers, co-ops and condominiums, schools, childcare programs, healthcare facilities and other organizations throughout New York, New Jersey and Connecticut.

Why Point-of-Use Testing Is Worth Doing

Several contaminants of genuine concern give no indication of their presence. Lead cannot be seen, tasted or smelled. Neither can PFAS. Water that looks and tastes entirely normal can still carry measurable concentrations, which is why laboratory analysis is the only reliable way to establish the position.

Clients commonly commission testing after changes in taste, color or odor, plumbing or street work, a property purchase, an occupant complaint, a regulatory or facility requirement, or simply because current point-of-use data is needed.

Testing can be commissioned for residences, apartment and condominium buildings, businesses, schools, childcare facilities and other properties. For homes or facilities serving infants, young children or pregnant women, contaminant selection may also reflect the greater sensitivity of those populations.

How Drinking Water Sampling Is Carried Out

Our laboratory technician performs the site visit and identifies every cold water point of use, including utility sinks, exterior taps and accessory lines feeding refrigerator dispensers.

The client confirms which points matter. Where a defined stagnation period is required, Olympian provides the preparation instructions before the visit so the sampling plan matches the testing objective.

Nothing is opened or dismantled. Bottles are filled at the existing taps exactly as they are, so the result describes the water occupants actually receive at that point of use, and samples are handled under documented chain of custody throughout.

Understanding Your Drinking Water Results

Reporting identifies the sampled locations, parameters analyzed, measured results and reporting limits, together with the applicable reference framework.

Where results need to be reviewed by a property owner, managing agent, facility manager, plumber, consultant or physician, that documentation is what allows the conversation to proceed on facts rather than impressions.

Health questions relating to a specific individual are properly directed to a physician, and the report is prepared so that conversation can be a specific one.

Common questions

Who should consider professional drinking-water testing?
Homeowners, renters, buyers, businesses, building owners, property managers, schools, childcare programs, healthcare facilities and other organizations may all have reasons to test water at the point of use.

What should a business test its drinking water for?

The scope depends on the building, plumbing, water source, occupancy and concern. Common business and facility testing can include lead, copper, bacteria, Legionella, PFAS, metals and broader potability parameters.

Is testing at the tap different from the utility testing the water supply?

Yes. Utility monitoring addresses the public system, while point-of-use testing evaluates water after it has traveled through the property’s own service connection, plumbing and fixtures.

Can a water test be customized for a school, office or residential building?

Yes. Sampling locations and parameters can be selected around the property type, how occupants use the water, any applicable requirements, and the specific questions the client wants answered.
