Water Testing
We provide residential and commercial water testing services for homeowners, property managers, hospitals, attorneys, municipalities, insurance companies, and health care professionals to evaluate the water quality in their homes and workplaces.
You can also call us to discuss air quality testing, mold testing, asbestos testing, XRF lead paint testing and lead dust testing. Visit our FAQs page for more information.
We are a leading provider of NYC lead water testing services for daycare and UPK centers applying for or seeking to renew their operating permits with the NYC Department of Health. Call to speak to licensed lead inspector today for a free price quote.
We have tested numerous private wells for water potability in rural areas of Long Island, Westchester, and Connecticut. Our experience includes water testing aboard cruise ships and private airplanes and for branches of the armed forces.

We are a leading provider of water testing services for owners and operators of NYC Daycare Centers, Schools and UPK Facilities seeking NYC Health Department permits and renewals related to Articles 43, 45, and 47 of the New York City Health Code.
To receive a permit from the New York City Department of Health to operate a school, daycare, or UPK facility, the Department of Health requires that an EPA Certified Lead Risk Assessor collect two water samples from each water outlet throughout the facility and submit the samples to a New York State ELAP accredited laboratory to evaluate levels of lead in the water. Water samples are required to be collected from every sink, fountain, bubbler, and cooler throughout the facility. Levels of lead should not exceed 15 parts per billion.
Call Angstrom Testing Services today if you are applying for a NYC Health department permit to operate a daycare, school, or UPK facility and need to have your water tested for lead content. We will send one of our EPA Certified Lead Risk Assessors to your facility to collect the required water samples.
Laboratory test results are available within one week. We will then email you within 24 hours, copies of the laboratory report, the chain of custody report, the laboratory's lead license, Angstrom Testing Services' EPA Lead License lead to conduct lead activities, and the Lead Risk Assessor's Lead Licence. After you receive these documents from us, you should email them to the NYC Department of Health as part of the permit application or renewal process.
WELL WATER TESTING
Well water samples are collected for laboratory analysis of Bacteria (Total Coliform and E-Coli), 19 heavy metals & minerals (including Lead, Arsenic and Chromium), 6 inorganic chemicals (including Nitrates and Fluoride), physical factors (including pH, Hardness and Alkalinity), and volatile organic compounds, to evaluate whether the water is safe to drink. The concentrations of these contaminants can be used to determine if a filtration or softening system may be needed, or to determine whether newly installed treatment systems are working properly to correct any bacteria or mineral issues that were previously detected. Results are typically available within 10 business days from the date the sample is collected. Contact one of our Technical Service Representatives at 516-724-4574 if you would like to arrange to have a sample of your well water collected and submitted for laboratory analysis.
Water Quality - General
The quality of your water is extremely important. Metal contaminants frequently enter into the drinking water as plumbing pipes, solder joints, fittings, and faucets naturally corrode over time and can cause several neuro-physiological problems when excessive amounts of these contaminants are consumed and enter into the bloodstream. Over time, the interior surfaces of plumbing-related components become impacted with minerals, salts, and corrosion-related deposits, which slowly dissolve into the water supply stream as changes in water pH, temperature, and alkalinity occur. Most contaminants have no taste, odor, or color, so their presence can only be determined by laboratory testing. Call Angstrom Inspection Services and have a sample of your drinking water tested today.
The EPA has established maximum contaminant levels (MCL's) for some metals, inorganic compounds (such as nitrates and nitrites), organic compounds (such as pesticides, herbicides, PCB's, and phthalates), bacteria, and radionuclides in drinking water. These MCL's are legally enforceable standards that apply to public water systems and limit the levels of contaminants in drinking water. Water samples can be collected from kitchen sink faucets, bathtub spigots, drinking wells, lakes, rivers, swimming pools, etc., and submitted for laboratory analyses to evaluate levels of contaminants.
Determining the bacterial quality of drinking water is the single most important water quality test. Why? Because one glass of water containing just a few disease organisms can cause illness. When minimal exposure creates an immediate health risk, that contaminant is known as an acute contaminant. Bacterial contaminants such as E. coli and fecal coliform in drinking water represent an acute health risk. In contrast, meaningful health risk from most chemical contaminants, such as arsenic, radon, or benzene, requires a long period of exposure. Consequently, these contaminants are considered chronic. The total coliform test is the starting point for determining the biological quality of drinking water. This test is performed frequently because of the acute risk that disease-causing organisms pose to the users of that water supply.
Total Coliform Test
Coliform bacteria are found in large numbers living beside pathogenic microorganisms in the intestinal tracts of warm-blooded animals. Masses of coliform bacteria are discharged from the intestinal tract with these animals' feces. If sewage enters water, the coliform bacteria in the sewage will be carried along and will survive in the water for long periods of time. Thus, the presence of coliform bacteria provides evidence that water has been polluted with sewage, and also indicates the possible presence of pathogenic microbes. The total coliform test remains the most commonly used standard for determining the bacterial quality of drinking water in the US and the world.
Fecal Coliform
This is a subset of the total coliform group. Fecal coliform bacteria generally originate in the intestines of mammals. They have a relatively short life span compared to other coliform bacteria. Their presence could be related to improper disposal of sanitary waste. Immediate public notice and a boil order to the users (within 24 hours) are required due to the higher likelihood of disease organisms also being present in water.
Escherichia coli (E. coli)
This is a species within the fecal coliform group. E. coli originate only in the intestines of animals including humans. As with other fecal coliform, they have a relatively short life span compared to nonfecal coliform bacteria. Their presence indicates a strong likelihood that human or animal wastes are entering the water system. Immediate public notice and a boil order (within 24 hours) are required due to a higher likelihood of disease organisms also being present in the water.
Heterotrophic Plate Count (HPC)
The heterotrophic plate count (HPC), formerly known as the standard plate count, is a procedure for estimating the number of live heterotrophic bacteria (requiring organic compounds of carbon and nitrogen for nourishment) in water. (HPC) is a microbial method that uses colony formation on culture media to approximate the levels of heterotrophic flora. HPC does not, however, give an indication of the types of organisms present or their sources. Most bacteria, including many of the bacteria associated with drinking water systems, are heterotrophs. This test can provide useful information about water quality and supporting data on the significance of coliform test results.
