Is Your Tap Water Actually Safe to Drink?
Drinking water potability testing determines whether water is safe for human consumption according to EPA drinking water standards and public health guidelines. Olympian Water Testing provides certified laboratory analysis for potable water contaminants including bacteria, lead, PFAS, heavy metals, VOCs, nitrates, and other harmful substances that affect drinking water quality. Clear water does not always mean safe water. Color, odor, and taste cannot reliably detect contamination. Only NELAP-accredited drinking water potability testing can confirm whether your water is safe for drinking, cooking, bathing, and everyday residential or commercial use.

Why Building Water Is Different
Your utility tests the main. Nobody tests your tap.
Municipal water systems are required to monitor water quality at the distribution main, not at your faucet. Once water enters your building’s private plumbing, it travels through pipes, fittings, and storage that no utility monitors. Aging materials, sediment, and stagnant sections can all affect what you actually drink.
Your building’s Consumer Confidence Report reflects supply water quality. Your tap reflects supply water quality plus everything that happens inside your building. Those are two different data points.
“I have tested buildings that received excellent utility compliance scores and still returned positive coliform at the tap. The report and your faucet are not the same thing.”
- What Potability Means
Potable water meets all EPA and state Maximum Contaminant Levels for bacteria, chemicals, and physical parameters. It is safe for drinking, cooking, food preparation, and brushing teeth.
- How We Confirm It
Certified field specialists conduct an on-site sampling event at your property. Samples travel under chain-of-custody to a NELAP-accredited laboratory. You receive a full written report with every parameter result and plain-language interpretation.
- How Long It Takes
Standard potability results are delivered in 7+ business days. Bacteria-only panels typically return in 24–48 hours. Expedited options are available for time-sensitive situations.
What We Do
Heavy Metals in Drinking Water We Can Test For

- Testing Can Solve Your Problem
- Ensure Your Water Safety & Learn What's in Your H2o
Copper
Copper testing is an important tool in identifying and managing contamination sources in order to protect the quality of your drinking water.
Iron
Iron testing is an important tool for ensuring compliance with regulatory standards for iron in drinking water and other water resources.
Bacteria
Bacteria like E. coli and coliform can cause serious illness, and it’s important to regularly test for them to ensure that your water is free of harmful bacteria.
Lead
Long-term exposure to contaminated water can lead to kidney damage and high blood pressure. We test lead in water with the latest technology.
Core Potability Parameters
Six parameters that define whether water is safe to drink
Every potability panel covers these fundamentals. Results are compared to EPA and state MCLs with written explanation of what each finding means for your water supply.
Total Coliform
Indicator organisms for contamination pathways. Presence requires investigation even without E. coli. The foundational potability indicator in every certified water test.
MCL: Zero per 100 mL
E. coli
Direct indicator of fecal contamination. Any detection in a potable supply requires immediate response, cease use for drinking and cooking until source is identified and corrected.
MCL: Zero per 100 mL
HPC Bacteria
Heterotrophic plate count measures overall bacterial population. Elevated HPC frequently precedes coliform detection in stagnant or inadequately maintained plumbing systems.
Guidance: <500 CFU/mL
Nitrates
Primary concern for infants under 6 months. Sourced from agricultural runoff, septic proximity, and geological formation. Required in NJ water testing compliance panels.
MCL: 10 mg/L as nitrogen
pH
Low pH accelerates corrosion and metal leaching from pipes. High pH reduces disinfection effectiveness. Both extremes affect potability, infrastructure, and health.
Acceptable: 6.5–8.5
Turbidity
Physical indicator of suspended particle load. Elevated turbidity can shield bacteria from disinfection and signals potential source water or treatment issues.
MCL: 1 NTU treated water

What People Say About Us
I used olympian for lead in water testing at our NYC child care. Prompt and professional.
Chris Braven
My landlord hired this company to test my water for heavy metals and chemicals. They were kind, professional and experienced. Results came in a reasonable amount of days and revealed problems with Iron and lead so my landlord got a plumber right away and are changing a few pipes.
Nancy Morales
With a baby on the way, we had our water tested for lead. Dennis went over the elevated results and helped us understand our next options to improve our water quality and make it safe for our family to drink.
Melissa Otivich
We operate multiple assisted living facilities and use this company for the potability testing.
Olivia Lewis
Dennis recommended strategic testing to determine the source of unknown water coming up through our buildings basement foundation. He hit the nail on the head when he said it was coming from a city source. We broke the ground to learn he was right.
Bryant Carter
Vinny came out and collected our water samples after our systems were sanitized. Very happy with the service.

FAQs
Consumers might test their water for a variety of reasons, including concerns about the quality of their tap water, the presence of strange odors or tastes, or the potential for contamination from lead or other contaminants. Regular water testing can help to identify any issues with the water and allow homeowners to take steps to address any problems that may have been identified.
The frequency of water testing will depend on a number of factors, including the quality of the local water supply, the age of the home, and any previous issues that have been identified. In general, it is recommended to test the water every year or two, or more frequently if there are any concerns about the quality of the water.
At Olympian Water Testing, we test for a wide range of contaminants, including bacteria, heavy metals (such as lead and copper), and chemicals like VOCs (volatile organic compounds) and THMs (trihalomethanes). Our comprehensive testing services help ensure that your water is safe for drinking, cooking, and everyday use. In addition to detecting harmful substances, we also analyze mineral content to assess fluoride levels, as fluoride benefits for dental health by strengthening enamel and preventing cavities. By identifying potential water quality concerns, we empower you to make informed decisions about filtration and treatment options. Our expert team utilizes advanced testing methods to provide you with accurate results and detailed insights into your water quality. Understanding the balance of essential minerals, including the fluoride and human health impact, is crucial for your overall well-being. By educating our clients on the importance of water quality, we support better health outcomes and promote peace of mind in every drop you consume.
The cost of water testing with Olympian Water Testing will vary depending on the specific test being conducted and the specific services being provided.
