THE HIDDEN PROBLEM

The most dangerous water quality problems have no visible, taste, or odor warning

Your utility tests their distribution system extensively — but at monitoring sites throughout the network, not at your specific tap. The water at your tap passes through your building’s service connection, risers, branch lines, and fixtures before it reaches you. Each of those components can affect water quality independently of what the utility monitors.
Lead in drinking water is colorless, odorless, and tasteless at any concentration of health concern. Arsenic in private well water looks and tastes like pure spring water. PFAS has no sensory signal whatsoever. Laboratory testing is the only form of detection.
The most important variable for residential water quality is the construction year of your building. Buildings before 1986 have lead-tin solder at every copper joint. Buildings before 1960 often have galvanized steel risers. Neither of these conditions is visible without opening the walls.
COMMON RESIDENTIAL SYMPTOMS
Brown or yellow water
Iron from galvanized risers or a distribution main event. Can also indicate accumulated sediment being disturbed.
Metallic taste or smell
Often copper corrosion at older fittings, or iron from galvanized pipe walls. May indicate pH imbalance.
No visible problem — testing for lead
Lead in drinking water is completely invisible. Pre-1986 building residents should test annually.
What We Do

Our Residential Water Testing Services

Identify potential lead exposure caused by aging pipes, solder joints, or legacy plumbing materials. Our testing follows EPA-aligned sampling protocols to detect lead levels directly from your home’s taps.

02. Copper & Corrosion Testing

Evaluate copper levels and corrosion indicators within your plumbing system. This testing helps identify pipe deterioration, water discoloration, and metallic taste issues.

03. PFAS & Chemical Screening

Test for PFAS (including PFOS/PFOA) and other emerging contaminants that may not be visible or detectable by taste. Laboratory analysis provides accurate results beyond basic water reports.

04. Bacteria & Microbial Testing

Screen for total coliform bacteria, E. coli, and other microbial concerns that can affect household water safety. Essential for homes with unusual taste, odor, or recent plumbing work.

Building Age Guide

What your home’s construction year tells you about your water quality risk

Pre-1940

Galvanized steel risers, lead-tin solder throughout, possible lead service line from street to building. Highest lead risk category in the Northeast.

Priority: Lead, Iron, Manganese

1940–1986

Copper plumbing with lead-tin solder at every joint. Lead-free solder not required until 1986. Any pre-1986 copper building warrants first-draw lead testing.

Priority: Lead, Bacteria

1986–2014

Lead-free solder standard. Brass fixture leaching possible at pre-2014 faucets. Primary concerns shift toward PFAS in municipal supply and bacteria.

Priority: PFAS, Bacteria

Post-2014

NSF/ANSI 61 lead-free fixtures and plumbing. Minimal lead risk from building plumbing. Focus on water supply chemistry and private well quality if applicable.

Priority: PFAS, Well (if applicable)

Why Testing Matters Even for City-Supplied Water

Many people believe city-supplied water is automatically safe, but the truth is that contamination can still occur after it leaves the municipal treatment facility. Aging infrastructure, lead service lines, or corroded household pipes can reintroduce harmful metals, bacteria, and PFAS chemicals into your drinking water. That’s why residential water testing is essential, even if your home receives treated city water.

Municipal testing is based on averages across an entire area, not the unique plumbing in your apartment or house. The water that reaches your tap may differ from what’s reported in city quality summaries. Repairs, road construction, or maintenance work can also disturb pipes, causing metals, rust, or sediments to temporarily rise in concentration. These fluctuations often go unnoticed without independent testing.

By testing your home’s water, you get results specific to your property, not assumptions based on public data. Our certified water testing experts identify contaminants that city systems might miss, such as trace lead or microbial growth in older plumbing. Even the smallest concentrations can accumulate over time, posing risks to your health. Olympian Water Testing Residential gives you the clarity and confidence that come from verified, science-based results, ensuring your family drinks the cleanest water possible.

Frequently Asked Questions

Have questions about residential water testing? Below are answers to some of the most common concerns homeowners have.

Municipal water quality reports reflect system-wide averages, not the specific conditions inside your home’s plumbing. Once water passes through aging pipes, fixtures, or service lines, quality can change. In-home testing provides property-specific results.

We commonly test for lead, copper, PFAS (including PFOS/PFOA), bacteria such as total coliform and E. coli, and other water quality indicators. Testing panels can be customized based on your property and concerns.

A certified technician collects water samples directly from selected taps using sterile containers and EPA-aligned procedures. Samples are securely transported to an accredited laboratory for analysis.

Most laboratory results are available within a few business days, depending on the type of testing performed. You will receive a clear report explaining findings and any recommended next steps.
