Phase I Environmental Site Assessment (ESA)

Persons involved in buying, selling, lending, or managing commercial real estate routinely need to establish if a subject property is "clean", or without "recognized environmental condition". This determination is commonly made with completion of a Phase I environmental site assessment (ESA). A Phase I ESA is completed by a qualified consultant following the nationally recognized standards published by ASTM. Scope of work of a Phase I ESA consists of reviews of environmental records, history, and physical setting, site reconnaissance, interviews, and report.

EESC has completed hundreds of Phase I ESAs. Properties types investigated have included: industrial, commercial, multi-family residential, self storage, special use, agricultural land, and unimproved land. Phase I ESAs have been completed in each of Arizona's fifteen counties, and all the major cities of Arizona, i.e., metropolitan Phoenix, metropolitan Tucson, Yuma, Flagstaff, Prescott, Casa Grande and vicinity, Sierra Vista, Nogales, Show Low, among others. EESC has completed numerous project throughout the White Mountains.

An EESC Phase I ESA report typically consists of between 15 to 25 pages of text plus APPENDIXES, i.e., photographs of site reconnaissance, selected aerial photographs, and selected maps.

Environmental Liability Screening (ELS) / Update of Phase I ESA

Less expensive alternatives to a Phase I ESA are an Environmental Liability Screening (ELS) or Transaction Screening, and update of Phase I ESA.

An Environmental Liability Screening follows a scope of work similar to a Phase I ESA, but with a condensed format, typically about 10 to 15 pages of text in bullet format plus APPENDIXES.

An Update of Phase I ESA consists of a review of due diligence since the date of completion of a prior Phase I ESA report. EESC can update reports of other consultants.

Water Resources & Groundwater

EESC provides water resources support to developers. EESC offers technical assistance to complete applications for Assured Water Supply (inside Active Management Areas (AMAs)) and for Adequate Water Supply (outside AMAs). Such assistance is usually in the form of a Hydrologic Study completed in accordance with guidelines of the Arizona Department of Water Resources (ADWR). The hydrologic study evaluates the sufficiency of the proposed water source to meet the long-term water supply needs of development.

EESC also provides a range of groundwater field services, including: overseeing borehole drilling and well installation, aquifer tests, water table measurements, and groundwater quality sampling.

In addition, EESC offers groundwater flow and/or contaminant transport interpretation and modeling.

EESC offers geology support services, including:

• mapping
• soil testing
• permeability evaluations
• evaluation of prospects of landscape materials (both sand and gravel (alluvial) or bedrock)
