Water Testing Services in NYC, Long Island, Westchester, Connecticut and New Jersey
Water Testing by Independent Environmental Professionals
Angstrom Testing Services provides independent water sampling and laboratory-based water testing for homes, apartments, schools, daycares, commercial buildings, public facilities, and private well systems.
Water testing may be used to evaluate drinking water quality, lead in tap water, bacteria, coliform, E. coli, heavy metals, volatile organic compounds, PFAS/PFOA, general water quality indicators, and potability concerns.
We provide water testing services in New York City, Long Island, Westchester, southern Connecticut, eastern New Jersey, and nearby areas.
Related environmental testing services include indoor air quality testing, mold testing, lead paint testing and lead risk assessments, and formaldehyde air testing.
What Is Water Testing?
Water testing is the collection and laboratory analysis of water samples to evaluate whether contaminants, bacteria, metals, or chemical compounds are present at reportable or regulated levels.
Depending on the concern, water samples may be collected from drinking water outlets, private wells, building plumbing systems, daycare or school fixtures, process water, or environmental water sources.
When Water Testing May Be Needed
- Buying, selling, or occupying a home with a private well
- Concerns about lead in drinking water from plumbing, fixtures, or service lines
- Water used by schools, daycares, camps, or child-occupied facilities
- Brown, cloudy, discolored, metallic, sulfur-like, or unusual-smelling water
- Water quality complaints in apartments, commercial buildings, or public facilities
- Suspected bacterial contamination after plumbing work, flooding, stagnant water, or well repairs
- Permit, due diligence, or regulatory-related sampling needs
What We Test For
- Lead and heavy metals
- Total coliform bacteria
- Fecal coliform bacteria
- E. coli
- Heterotrophic Plate Count
- Volatile organic compounds
- PFAS / PFOA
- pH, turbidity, hardness, and general chemistry
- Private well potability parameters
- Source and cause investigations
Lead in Drinking Water Testing
Lead in drinking water often comes from building plumbing, solder, fixtures, valves, fountains, or service-line materials rather than from the source water itself. Sampling can help determine whether lead is present at a specific outlet or group of outlets.
Angstrom Testing Services provides lead-in-water sampling for homes, apartments, schools, daycares, commercial buildings, and public facilities. Samples are submitted to an appropriate laboratory for analysis, and results are reviewed in context with the sampling location, fixture type, and project objective.
Water Testing for Schools and Daycares
Schools, daycares, and child-occupied facilities may need lead-in-water testing, bacteria testing, or potability testing depending on the facility type, permit requirements, and jurisdiction.
New York State school drinking-water requirements and New York City child-care requirements should be evaluated separately because the action levels, sampling requirements, and reporting procedures may differ.
Angstrom Testing Services can collect water samples, coordinate laboratory analysis, document sample locations, and provide reports suitable for facility records, permit support, or follow-up review.
Private Well and Potability Testing
Private well testing may be needed before property transfer, after well work, following flooding, when water quality changes, or when a homeowner wants to evaluate drinking water quality.
Potability testing may include bacteria, metals, nitrates, general chemistry, and other parameters depending on the location, well type, and project objective.
Bacteria and Coliform Testing
Bacteria testing may be recommended for private wells, drinking water outlets, buildings with stagnant plumbing, water intrusion concerns, and suspected sanitary contamination.
Common microbiological tests include total coliform, fecal coliform, E. coli, and Heterotrophic Plate Count. These tests can help evaluate whether water quality may be affected by environmental bacteria, fecal contamination, stagnant plumbing, or system hygiene concerns.
Total Coliform
Total coliform bacteria are commonly used as an indicator of possible water system contamination or sanitary defects.
Fecal Coliform and E. coli
Fecal coliform and E. coli findings may indicate fecal contamination and can require prompt follow-up depending on the water system, facility type, and regulatory context.
Heterotrophic Plate Count
Heterotrophic Plate Count can provide general information about bacterial populations in water and may be useful when evaluating stagnant plumbing, wells, tanks, filters, or building water systems.
How Water Sampling Works
- We review the property type, water source, concern, and testing objective.
- We identify appropriate sampling locations, such as faucets, fountains, wells, plumbing outlets, or source-water locations.
- Samples are collected using appropriate containers and sampling procedures for the requested laboratory methods.
- Samples are submitted to a qualified laboratory for analysis.
- Results are reviewed and summarized in a written report or letter, depending on the project scope.
What You Receive
- Water sampling by trained environmental professionals
- Laboratory analytical results
- Sample location documentation
- Interpretive comments when included in the project scope
- Written report, letter, or summary suitable for client records
- Recommendations for additional evaluation when appropriate
