Environmental Concerns We Evaluate in White Plains and Westchester County
Project needs vary by property age, building type, renovation history, water source, prior leaks, HVAC systems and the purpose of the assessment.
Basements, Roofs and Hidden Moisture
Plumbing leaks, roof or window failures, basement moisture, condensation and prior flooding can lead to questions about hidden mold, damp materials and indoor air quality.
Mold testing and inspectionLead, Asbestos and Renovation Planning
Renovation, demolition or deterioration of older building materials may require evaluation for lead, asbestos or construction dust before, during or after work.
Asbestos testing servicesWater Quality and Selected Private-Well Projects
Drinking-water projects can be scoped for lead, bacteria, metals, PFAS, VOCs, Legionella or other parameters based on the property, water source and reason for testing.
Water testing servicesUST and Phase II Environmental Questions
Commercial, redevelopment and residential properties may require evaluation of known or suspected underground storage tanks, historical site concerns or targeted subsurface investigation.
Silica, Lead, Asbestos and Settled Dust
Renovation, demolition and construction can generate airborne or settled dust that may warrant project-specific testing for silica, lead, asbestos or other contaminants.
Silica and dust testingHVAC, Odors and Indoor Air Quality
Air handlers, fan-coil units, condensate systems, dust reservoirs, ventilation problems, smoke and chemical odors may require inspection, direct-reading measurements or targeted sampling.

How an Environmental Testing Project Works
Discuss the Concern
We review the property type, location, complaint, building history, suspected source, and reason for testing.
Develop the Scope
The inspection, measurements, sample types, locations, and laboratory methods are selected for the project objective.
Inspect and Sample
Relevant areas are evaluated, documented, measured, or sampled according to the agreed scope and site conditions.
Interpret and Report
Findings are interpreted with the field observations, sample locations, laboratory results, and project limitations.

What types of properties do you inspect?

Can you test private well or drinking water in Westchester County?
Yes, depending on the property and requested parameters. Projects may be scoped for bacteria, lead, metals, PFAS, VOCs or other analytes. The appropriate laboratory, containers and holding times depend on the selected test panel.
Can you evaluate a suspected underground storage tank or Phase II concern?
Yes. Angstrom provides underground storage tank assessment and Phase II environmental investigation services. The scope depends on the known site history, suspected source, property records and purpose of the investigation.
Will I receive a written report?
Yes. Depending on the project scope, documentation may include inspection findings, sample locations, field measurements, photographs, laboratory results, interpretation, limitations, and recommended next steps.
Can testing identify the source of an odor or indoor air quality problem?
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.
Is environmental testing the same as a medical evaluation?
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.
