Cleaning Up Contaminated Sites and Reinvesting Is Good for Everyone.
Preparing Sites for redevelopment is a tangible benefit of the work we do. Cleaning up and reinvesting in these properties protects the environment, reduces blight, and takes development pressures off greenspaces and working lands.
Cleanup and redevelopment of contaminated Sites can encourage higher property values and create jobs, as well as positively impact the local economy by creating a safer, healthier urban space to house businesses and residences. Many of our projects focus on enabling or restoring the development of soil and groundwater contaminated sites.
In 2009 a former automotive fueling and service station was demolished. Acuity was retained to analyze soil and groundwater, recommend a solution and remediate the Site so the owner could redevelop it.
In addition to loosing money by the day on property they couldn’t develop, this client used their own assets to pay for remediation efforts. It was critical to have a plan to close the Site as quickly as possible – and they needed that plan before they could start the cleanup. AcuityES worked to establish a guaranteed maximum cost for completion within a specific timeframe.
Customized Reagent Expedites Site Redevelopment
The family of contaminants usually found at these types of sites is called Total Petroleum Hydrocarbons (TPH). TPH is a term used to describe a broad family of several hundred chemical compounds that originally come from crude oil.
Residual petroleum impacts were present in soil and groundwater at concentrations above applicable criteria including: impacts: benzene, toluene, ethyl-benzene and xylenes (BTEX), TPH-GRO, and methyl tert-butyl ether (MTBE). MTBE were initially identified as Site-derived constituents of concern (CoCs) originating from the former Leading Underground Storage Tank (LUST) system.
The solution included source area removal by excavating soil, fuel distribution piping, concrete debris and conduit – and disposing of the waste materials off-Site.
To enhance microbial degradation in the capillary fringe and groundwater, a slow-release, chemical oxidizer that contained essential nutrients was applied to the base of the excavation.
The Site is now planned for retail or restaurant development. Download the full case study here.
