Private well testing

Professional Private Well Water Testing in NY, NJ and CT

01

Well and System Walkthrough

Well type, casing, pressure tank, existing treatment and any point of entry equipment are identified before a bottle is opened, because equipment already installed changes what a raw sample means.

02

Sampling Point Decision

Raw water ahead of treatment, treated water after it, or both. Testing only the treated side tells you whether the equipment is working but not what is in the aquifer.

03

Collection and Field Record

Bottles are filled in the order the analyses require, with preserved containers handled separately. Conditions, weather and recent well use are recorded.

04

Custody and Transfer

Samples are sealed, logged and moved under documented chain of custody with holding times observed throughout.

05

Reporting

Values, methods, reporting limits and sampling points are stated, with results reported in full. The finding stands on its own.

A private well draws directly from groundwater, and the composition of that water reflects local geology, land use and the construction of the well itself. Unlike a public supply, no utility treats it, monitors it or reports on it. Responsibility for understanding the water rests with the property owner.

Olympian Water Testing provides professional well water testing for homeowners, property buyers and sellers, real estate professionals and building owners across northern and central New Jersey, Rockland, Putnam and Westchester, Long Island and Connecticut.

Why Private Wells Require Owner Initiated Testing

Private wells fall outside federal drinking water regulation. Nothing is analyzed unless the owner arranges it, which means a well can serve a household for years without anyone establishing what it contains.

Testing is particularly appropriate when a well is newly drilled or reconditioned, at the point of a property transaction, after flooding or heavy storms that may bring surface water into the aquifer, when household composition changes, and where a pregnant woman or young child will be drinking the water.

Requirements also attach at the point of a transaction in New Jersey, which is addressed in its own right below.

Designing a Well Panel That Reflects Your Property

A meaningful well analysis is built around the property rather than selected from a fixed list. Well construction and casing condition, the presence and position of any existing treatment, local bedrock and soil characteristics, agricultural or septic influence, and proximity to known release points all shape which parameters warrant inclusion.

Bacteriological indicators, a metals suite covering arsenic, iron, manganese and lead among others, nitrate and general chemistry, and physical parameters commonly form the base. PFAS, volatile organic compounds and pesticide screens are added where the geology, land use or history of the area supports it.

Where treatment equipment is already installed, raw and treated water are sampled as separate points so the aquifer condition and the performance of the system can each be assessed. Samples are collected in the order the analyses require, with preserved containers handled separately and holding times observed throughout.

Understanding Your Well Water Results

Our well reporting identifies every parameter selected, the method applied, the reporting limit achieved and the measured value, together with the sampling points and the sampled location.

Groundwater is not static. Water tables move, recharge events can mobilize surface influence, and a well that reads one way in a dry season may read differently after a wet one. A single analysis is a defined snapshot, and that context is stated plainly in the reporting.

Olympian Water Testing assists owners in interpreting results against the applicable state and county reference framework, which varies considerably more for private wells than for public supplies.

New Jersey PWTA Private Well Testing

New Jersey legislates private well testing directly. The Private Well Testing Act, commonly referred to as the PWTA, applies at the point of sale of a property served by a private well and to landlords leasing such properties, and it requires that the results of a defined analysis be provided to the buyer or the tenant.

The PWTA parameter list is set by regulation and varies by county, since certain parameters are required only where the underlying geology warrants them. Lead is among the parameters the Act addresses, alongside bacteriological indicators, nitrate and a defined set of metals and general chemistry.

Olympian Water Testing conducts PWTA analyses across northern and central New Jersey and works to whatever the Act requires in the county concerned. Where a client is transacting, we state clearly which parameters the PWTA mandates and which are elective additions, so nothing required is omitted and nothing unnecessary is purchased.

Where a bacteriological result does not meet the standard, the water is treated as unsuitable for consumption until a subsequent analysis demonstrates otherwise. We set that position out plainly rather than leaving a buyer or a seller to interpret it.

Clear Data for Owners Who Are Their Own Utility

The purpose of well testing is to give an owner the visibility a municipal customer receives automatically. With a properly designed panel and a controlled collection process, that information is straightforward to obtain and straightforward to act on.

Reports are prepared so they can be taken directly to a treatment contractor, a county health department, a lender or a buyer.

Olympian Water Testing has provided independent professional water testing across New York, New Jersey and Connecticut since 1991, with NELAP accredited laboratory analysis. Water-testing support is available 24/7.

Common questions

What should I test my private well water for?

The testing scope should reflect your specific concerns, the property, local geology, surrounding land use, well history and any transaction requirements. Common parameters include bacteria, nitrate, arsenic, metals and water chemistry, with PFAS, VOCs, pesticides or radiological testing added when appropriate.

How often should a private well be tested?

Routine testing is useful because groundwater and well conditions can change. Additional testing may be appropriate after flooding, well repairs, changes in taste or odor, nearby environmental concerns or before a real-estate transaction

What is PWTA testing in New Jersey?

PWTA refers to New Jersey’s Private Well Testing Act. Qualifying real-estate transactions involving potable private wells require specified testing, and the required parameters can depend on the property location.

Can two neighboring wells have different water-test results?

Yes. Well depth, construction, geology, groundwater flow and nearby sources of contamination can differ from property to property, so one neighbor’s result does not establish the quality of another well.

Request Professional PFAS Water Testing

Testing can be scoped for homes, buildings, private wells and other properties around the water source and the PFAS questions you need answered.
