View silica testing servicesTargeted environmental bacteria sampling for sewage, surfaces, air, HVAC or selected water concerns, plus separate Legionella sampling for building water systems and cooling-tower projects.
View bacteria testing servicesEvaluation of suspected or known underground storage tanks, historical fill and vent piping, property records, and site conditions associated with residential or commercial heating-oil tanks.
View UST servicesAssessment of accessible air handlers, fan coil units, blower compartments, coils, condensate pans, duct liner, registers, and HVAC-related mold or odor concerns.
View HVAC mold assessmentsLocal projects vary by property age, construction, water source, renovation history, prior leaks, heating systems, occupancy and the reason documentation is needed.
Basement seepage, plumbing failures, roof or window leaks, condensation and prior flooding can lead to questions about hidden mold, damp materials and indoor air quality.
Mold testing and inspectionRenovation, demolition or deterioration of older building materials may warrant lead, asbestos or construction-dust evaluation before, during or after work.
Asbestos testingLong Island's drinking-water supply depends on its groundwater aquifer system. Testing may address lead, bacteria, PFAS, metals, VOCs, private-well concerns or other project-specific drinking-water parameters.
Residential and commercial properties may require investigation of a known or suspected underground storage tank, former fill and vent piping, or documentation before a transaction.
Underground storage tank servicesRenovation and construction can generate dust containing silica, lead, asbestos or other materials. Sampling can be scoped to the specific contaminant and project objective.
Silica and dust testingHVAC moisture, drain pans, fan-coil units, dust reservoirs, chemical odors, smoke and ventilation concerns may require inspection, direct-reading measurements or targeted sampling.
Indoor air quality testingWe review the property type, location, complaint, building history, suspected source, and reason for testing.
The inspection, measurements, sample types, locations, and laboratory methods are selected for the project objective.
Relevant areas are evaluated, documented, measured, or sampled according to the agreed scope and site conditions.
Findings are interpreted with the field observations, sample locations, laboratory results, and project limitations.
Angstrom’s Rockville Centre office supports environmental testing projects throughout Nassau County, Suffolk County, Queens, and nearby Long Island communities. Service availability depends on the project type, required licensing, site conditions, schedule, and requested turnaround time.
Properties may include single-family homes, apartments, condominiums, cooperative buildings, offices, schools, daycares, health care facilities, retail spaces, warehouses, municipal buildings, and other commercial or institutional facilities.
Angstrom provides mold testing, indoor air quality assessments, asbestos testing, lead paint and lead dust testing, water testing, formaldehyde and VOC testing, silica and construction-dust testing, HVAC mold assessment, bacteria testing, Legionella testing, and related industrial hygiene consulting.
Yes. Angstrom Testing Services is based in Rockville Centre and performs environmental testing and industrial hygiene consulting throughout Nassau County, Suffolk County, Queens, and nearby areas.
No. Angstrom Testing Services provides independent testing, inspection, sampling, consulting, and reporting. We do not perform mold remediation, asbestos abatement, lead abatement, duct cleaning, reconstruction, or cleanup contracting.
Yes. The Rockville Centre office supports projects throughout Nassau County, Suffolk County, Queens, and nearby Long Island communities, depending on the testing type, required licensing, schedule, and project scope.
Projects may involve homes, apartments, condominiums, cooperative buildings, offices, schools, daycares, health care facilities, commercial buildings, institutional properties, and legal-support matters.
Yes, depending on the location and requested parameters. Private-well projects can be scoped for bacteria, metals, PFAS, VOCs or other analytes based on the property and reason for testing. The required laboratory, containers and holding times depend on the test panel.
Yes. Angstrom provides underground storage tank assessment services for properties where a buried tank, former tank, fill pipe, vent pipe or historical heating-oil system is suspected. The exact scope depends on the property records and site conditions.
Yes. Depending on the project scope, documentation may include inspection findings, sample locations, field measurements, photographs, laboratory results, interpretation, limitations, and recommended next steps.
Testing can help evaluate possible sources, but odor and indoor air quality investigations often require a combination of building-history review, inspection, source tracking, field measurements, targeted sampling, and interpretation of conditions present during the assessment.
No. Environmental testing evaluates selected building conditions and contaminants. It does not diagnose illness or determine whether a particular condition caused a medical symptom. Medical concerns should be discussed with an appropriate health care professional.
Describe the property type, location, building history, odor, moisture, dust, mold, asbestos, lead, water, VOC, HVAC, or other environmental concern. Angstrom can help define an appropriate inspection and testing scope for the project.
