Our Environmental Testing Services

More About Our Services

Arch Environmental Group LLC is an independent environmental testing and inspection company serving homeowners, landlords, property managers, and commercial facility teams across California’s Central Valley. We test, sample, and document, and we produce a clear written report backed by accredited laboratory analysis. Because we don’t perform the remediation ourselves, our findings are unbiased: we have no incentive to find a problem that isn’t there, or to miss one that is. Below is the full range of what we handle.

Building hazard testing

Before a renovation, demolition, or property sale, you need to know what’s in the structure. Arch Environmental Group LLC holds certifications as a Certified Asbestos Consultant and Lead Inspector/Assessor, and our microscopists are NIOSH 582 credentialed, the credentials California and federal rules require before this work can be signed off on.

• Asbestos testing and inspection, pre-renovation and pre-demolition surveys, bulk sampling, and NIOSH 582 fiber analysis.
• Lead paint testing and inspection, identification and risk assessment for pre-1978 buildings and child-occupied facilities.
• Clearance testing, independent post-remediation verification that a space is ready for re-occupancy.
• Environmental site assessments, Phase I due-diligence research and site evaluation for commercial and mixed-use properties.

Air quality, mold, and allergens

When the air in a home or building is causing symptoms, or a moisture problem may have seeded mold, testing tells you what’s actually there before anyone spends money on a fix.

• Mold inspection and testing, visual assessment plus air and surface sampling with laboratory analysis.
• Indoor air quality testing, sampling to identify particulates, fibers, and other airborne concerns.
• VOC and formaldehyde testing, laboratory panels for off-gassing from flooring, cabinetry, and finishes.
• Allergen testing and HVAC and duct system assessments, evaluating what’s circulating and where it’s coming from.
• Post-flood mold assessment, documenting moisture and mold conditions after a water event so remediation is scoped correctly.

Water, radon, and contamination

• Water quality testing, laboratory analysis of drinking and source water.
• Radon testing, measurement to determine whether levels warrant mitigation.
• Sewage contamination assessment, independent documentation of Category 3 water conditions and contamination boundaries.

Consulting and oversight

• Remediation oversight, independent monitoring and clearance of a remediation contractor’s work, we oversee and verify, we don’t perform the abatement.
• Environmental compliance consulting, guidance on Cal/OSHA, EPA, and San Joaquin Valley Air Pollution Control District requirements.
• Litigation support and forensic sampling, defensible sampling and reporting for disputes and claims.

Every one of these services ends the same way: with documentation you can act on and hand to a contractor, adjuster, or building department. If you’re not sure which service applies to your situation, call (559) 296-2088 and describe what you’re seeing, and we’ll point you in the right direction.
