      The environmental professionals at Mark Yinger Associates have been performing environmental site assessments (ESAs) in Oregon and Washington for more than 15 years for varied commercial properties:  residential, agricultural, industrial, retail, manufacturing and medical.

      All Mark Yinger Associates Phase I Environmental Site Assements in Oregon & Washington are conducted in accordance to the Standard Practices for Environmental Site Assessments (ASTM 1527-13).  The finding of an "recognized environmental condition" or environmental liability during phase i inquiries means the likely presence of contamination on a property from hazardous substances or petroleum products.  The source of the contamination may not be on the subject property.

      Hazardous vapor intrusion into buildings has been recognized as a significant environmental liability in recent years.  The Standard Guide for Vapor Encroachment Screening on Property involved in Real Estate Transactions (ASTM  E-2600-10) was published June 14, 2010.  We will perform vapor screening in accordance with this guidance when hazardous vapor intrusion is suspected. 

       A phase i environmental site assement may also include screening for other potential environmental liabilities such as lead-based paint, asbestos, mold, lead in drinking water, radon, and wetlands.


Phase II Environmental Site Assessments (ESA)

     If a Phase I Evironmental Site Assessment identifies recognized environmental conditions or concerns, our Phase I report will include specific recommendations for Phase II investigations, including cost estimates.

      Phase II investigations typically involve sampling of subsurface soil and groundwater and the laboratory testing of those samples for contaminants.  The scope of a Phase II ESA is tailored to each property, taking into consideration its former, current and likely future use.


Phase III Environmental Site Assessments (ESA)

     A Phase III Environmental Site Assessment is the remediation of the contamination found in soil or water during the  Phase II Environmental Site Assessment.  The Phase II delininates the physical extent of the contamination and the chemical constituents of the contamination.  The Phase III is the removal or on-site remediation to meet the state and federal guidelines.
