Environmental Services in Maricopa County, AZ
Maricopa County sits on desert alluvium where collapsible soils compress suddenly on first wetting, a failure mode compaction testing is built to prevent. From ESA through construction support, Maricopa County projects see findings early, before Arizona closings put real money at risk. Historical records on Maricopa County parcels get pulled and read, not skimmed, which keeps AZ redevelopment moving. Maricopa County clients get defined-scope mobilizations with laboratory support, partnering with Arizona licensed professionals where sealed deliverables are required.
- Phase I Environmental Site Assessments for acquisitions and refinancing

FAQ · Maricopa County
When is a Phase I ESA required?
Lenders typically require a Phase I ESA on commercial property transactions to establish the innocent-landowner defense under CERCLA. It is a records-and-reconnaissance study — no sampling is performed.
What triggers a Phase II?
A Phase II is recommended when the Phase I identifies recognized environmental conditions, such as historical industrial use, nearby releases, or suspect storage tanks.
