Water Testing - Bacteria
Determining the bacterial content in drinking water is the single most important water quality test. One glass of water containing just a few disease organisms can cause severe illness.The total coliform test is the starting point for determining the biological quality of drinking water. This test is performedfrequently because of the acute risk that disease causing organis is pose to the users of that water supply.
Total Coliform Test
Coliform bacteria which 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 when samples test positive 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.
Well Water Testing for Water Filtration Systems
Angstrom Testing Services specializes in collecting well water samples 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) and physical factors (including pH, Hardness and Alkalinity). The concentrations of these contaminants are extremely useful for anyone interested in regularly monitoring their well water quality, trying to determine if a filtration or softening system is needed, or determining if new treatment systems are working 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.
Specialized tests to ensure safety of water can also be performed, whether from drinking water (potable) or other sources such as ponds (non-potable). These include tests for fecal Streptococcus, Pseudomonas, Staphylococci and Legionella.
Please call Angstrom Inspection & Consulting Services if you would like your water tested for laboratory analyses of any of the contaminants described above (516)724-4574 (c) (516)594-1204 (o)
Water Testing - 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 Testing Services today and have a sample of your drinking water
Lead in Water - Daycare Facilities & NYC Schools
We are a leading provider of water testing services for owners and operators of NYC Schools and Daycare Facilities seeking NYC Health Department permits related to Articles 43, 45, and 47 of the New York City Health Code. Call Today for a Price Quote (516) 724-4574 if you are applying for a permit and need to have the water tested for lead content.
To receive a permit from the New York City Department of Health to operate a school or daycare facility, the Department of Health requires that an EPA Certified Lead Risk Assessor collect water samples from each of the supply sources throughout the facility and submit the samples to an accredited laboratory to evaluate levels of lead in the water. Water samples are required to be collected from each of the sinks, fountains, bubblers, and coolers throughout the facility. Levels of lead should not exceed 15 parts per billion.
Call Angstrom Inspection & Consulting Services today if you are applying for a permit to operate a daycare facility and need to have your water tested. We will send one of our EPA Certified Lead Risk Assessors to your site to collect water samples and submit the samples to an accredited laboratory to evaluate levels of lead in the water. Laboratory results are available within one week. We will then email you within 24 hours, a copy of the laboratory report, the chain of custody report, the laboratory's license authorizing them to analyze the samples for lead content, and our EPA Lead Risk Assessor License. After you receive these documents from us, you should send them to the NYC Department of Health as part of the permit application process.
