Ember Environmental Services specializes in providing Phase I Environmental Site Assessments (Phase I ESA) for real estate due diligence. A Phase 1 ESA is typically required by most lenders for commercial/industrial building sales and can uncover valuable environmental information regarding the property. With a careful review of environmental records and an on-site visit, an Environmental Site Assessment can alert you to spills or contamination impacting your property. In addition it can highlight past high-risk occupants and unearth other environmental records and issues.  If any of these findings can threaten the environment or pose a risk to human health it is important to find out before the sale. This can help you understand any potential liability or how it may effect the property’s value.

The Phase 1 Environmental Site Assessment is an important and often complicated report. Because of this it is important that your Phase I ESA follows ASTM E1527-13 standards.  Furthermore, this is also the only standard that can help satisfy the All Appropriate Inquiries (AAI) requirements of the EPA’s Comprehensive Environmental Response, Compensation, & Liability Act (CERCLA). This is important if you are attempting to qualify for an Innocent Landowner defense. At Ember we have experience dealing with a wide variety of commercial and industrial property types. These include office buildings, auto repair shops, breweries, warehouses, retail shops, multi-family housing, and more.

In addition to the Phase 1 ESA Ember also offers Environmental Transaction Screens as well as Property Condition Assessments (PCA) through our sister company Certified Inspections and Consulting. These services are offered to the greater midwest including Illinois, Indiana, Iowa, Missouri, Wisconsin, Minnesota, Michigan, Kentucky and Ohio.

What’s In a Phase I ESA?

Historical Research

Ember reviews historical resources such as fire insurance maps, city directories, and aerial photos to ascertain past uses of the property.

Regulatory Review

Local, state, and federal regulatory databases and records are reviewed for current or past environmental issues regarding the property and surrounding area.

Site Reconnaissance

A site visit is made to inspect the property for indications of contamination, spills, or other environmental concerns.


Ember may interview current owners, property managers, occupants and tenants, government officials, and the prospective buyer for knowledge of the property.


A Phase I ESA report following ASTM E1527-13 is prepared with the appropriate information gathered from the Phase I Environmental Site Assessment process.
