Environmental Services

Company founders Mr. Eric Hanson and Mr. Kirby Van Vleet have over 50 years combined experience as professional environmental consultants.  Our technical staff is a highly qualified team having extensive experience in all phases of groundwater development, contaminant hydrogeology, groundwater and soil remediation, underground storage tank remediation, environmental assessments and associated environmental issues.  We work with our clients to achieve their goals in an efficient, cost effective manner.

Hanson Van Vleet offers a comprehensive environmental site assessment (ESA) program, providing Phase I, II and III site assessments for commercial and residential properties. ESAs are typically performed as a preliminary, qualitative, environmental investigation conducted to disclose environmental concerns (liability/risk) prior to the transfer of commercial and/or industrial property.  Current environmental laws suggest that the transfer of environmentally contaminated property may result in liabilities to prior owners, purchasers and/or lenders.  There are presently no federal or state laws governing the methods of performing both Phase 1 and Transaction Screen Assessments, however, the American Society for Testing and Materials (ASTM) have established recommended guidelines.  Hanson Van Vleet performs all ESAs in accordance with the current ASTM guidelines.  We will also expand the scope of ESAs based on specific client requirements.

Hanson Van Vleet recognizes the need for cost effective ESA services to support your commercial real property transactions.  We offer a very competitive pricing schedule and provide our client a product of the highest quality.
