William Hopper has been in the environmental industry since 1998. His experience includes conducting environmental field investigations, operation and maintenance of soil and groundwater remediation systems, landfill monitoring, project and client management, and managing and developing environmental due diligence programs.

​

He has a thorough understanding of environmental rules and regulations, and has extensive experience conducting environmental due diligence Phase I’s and Phase II’s at thousands of commercial and industrial properties, preliminary and comprehensive response actions including the removal of underground storage tanks (USTs), performing emergency response actions, and performing compliance activities at gasoline service stations throughout New England.

​

Mr. Hopper regularly interfaces with clients on technical matters and provides technical assistance to clients inquiring about possible environmental concerns on properties they are looking to purchase.

​

Mr. Hopper has completed ASTM Phase Is, Transaction Screens, Database Reviews, Peer Reviews, and SBA Records Search & Risk Assessments (RSRAs) for properties across the United States.  He has managed and coordinated the completion of thousands of environmental due diligence projects for a significant number of small and regional banks, commercial and industrial clients, and individual commercial loan officers throughout the United States.

​

Mr. Hopper completed RSRA and Lead Risk Assessment for a local New Hampshire bank for a building being converted into a daycare and applying for a United States Small Business Administration (US SBA) 504 loan. Lead paint was identified in the areas that were to be occupied by children and worked with the property owner, bank, and contractor to remove lead painted components which resulted in clean test results allowing the loan to move forward and the business to open.

​

Mr. Hopper was the project manager for a medium-sized Massachusetts bank during an ASTM Phase I ESA. Due to the presence of out of service in-ground hydraulic lifts and suspect subsurface structures, a ground penetrating radar (GPR) survey was completed and identified two (2) waste oil USTs at the Site. Laboratory analysis of soil obtained during a Phase II Limited Subsurface Investigation revealed extractable petroleum hydrocarbons (EPH) fractions C19-C36 aliphatics and C11-C22 aromatics at concentrations exceeding the Massachusetts Department of Environmental Protection (MassDEP) RCS-1 Reportable Concentration and S-1/GW-1, S-1/GW-2 and S-1/GW-3 Method 1 Risk Characterization Standards for unrestricted future use of the Site.
