Water-quality data at the property level

Testing can document conditions at specific outlets and water sources for a clearer picture of the property.

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.'

Professional sampling & analysis

Olympian provides on-site collection with accredited environmental laboratory analysis for the parameters selected.

Water quality reporting

Professional Water Quality Testing and Reporting

A water quality result is a statement about a defined sample, collected at a defined point, under defined conditions. Its usefulness rests as much on the documentation surrounding it as on the figure itself, particularly where the result will be reviewed by parties with differing interests.

Olympian Water Testing provides professional water quality testing and reporting for boards, managing agents, building owners, engineers, institutional clients, counsel acting in transactions and private clients throughout New York, New Jersey and Connecticut.

Why Documentation Determines Credibility

Two analyses of the same property can differ legitimately, because stagnation, fixture selection, recent disturbance and the presence of treatment equipment all influence what a sample contains. A result reported without those conditions cannot be assessed on its merits.

Olympian Water Testing provides the required pre-sampling instructions, identifies each sampling point, and maintains chain of custody from collection through laboratory receipt.

Where a report is later reviewed by an engineer, a lender, an insurer, a regulator or opposing counsel, that record allows the figures to be assessed rather than argued over.

Method, Reporting Limit and Reference Framework

Every parameter is reported with the analytical method applied and the reporting limit that method achieved. Parameters not detected above the reporting limit are listed explicitly, establishing the scope of the analysis rather than leaving it to inference.

Each measured value is set against the applicable published reference, with the category of that reference identified, since enforceable limits, non enforceable health based goals and advisory guidance carry materially different weight.

Method selection follows the client’s objectives and the parameters of concern, and may be adjusted where doing so preserves holding times and the integrity of the result.

Reporting Built for Scrutiny

Multi point programs across schools, childcare premises and multifamily portfolios are documented to the same standard as a single household visit, with each point identified individually.

Where commercial tenancies share a supply with residential units, findings are reported by point so each party reads the section that concerns it.

Where a property carries a regulatory obligation, reporting is prepared to satisfy the documentation that obligation requires.

Independent Analysis Since 1991

Olympian Water Testing has operated across the New York metropolitan region since 1991, from five departure locations into New York, New Jersey and Connecticut.

NELAP accredited laboratory analysis applies throughout, and a specimen report is available on request prior to engagement.

One of our consultants determines parameter selection with you, and enquiries are received around the clock throughout the year.

Common questions

What does a water-quality test actually measure?

It measures only the parameters included in the laboratory scope. Results may report concentrations of metals, chemicals or minerals, presence or absence findings for microbiological parameters, and physical or chemical characteristics such as pH or turbidity.

Why can water quality vary from one faucet to another?

Different fixtures, branch lines, plumbing materials, water-use patterns and stagnation conditions can create different results within the same property.

Do water-quality results expire?

A laboratory result describes the sample collected at that time and location. Changes to plumbing, water source, treatment, building use or environmental conditions can make later testing appropriate.

What should I do if a water-quality result is unusual?

First confirm what was tested, the sampled location and the applicable comparison value. Follow-up sampling can then be designed to confirm the finding or narrow down where the condition may be occurring.
