ECT completed site characterization of a brownfield property using a membrane-interface probe (MIP) technology. The purpose of the MIP investigation was qualitatively determining if, and at what depth, remnant petroleum or chlorinated solvent contamination may exist beneath the site as a result of past uses. The MIP investigation also provided information regarding soil types and depth to limestone at each MIP location.
The MIP is a screening tool with semi-quantitative capabilities acting as an interface between volatile contaminates at depth in the soil and gas phase detectors at the surface. The MIP log shows the response of the MIP detectors with depth in the soil. The MIP data acquisition system makes this log by incorporating the travel time required for the membrane sweep gas to reach the MIP detectors at ground surface, thus converting the detector time data into MIP response with depth data.
The results from MIP evaluation corroborated existing data collected in 1996 using flame-ionization and photo-ionization detectors on a former CSX Transportation property.
ECT’s Brownfields Interaction Team completed this site characterization for the City of Live Oak to evaluate the feasibility of redeveloping the property.
ECT’s Brownfields Interaction Team use their backgrounds in state and local government, real estate, economic development, finance, public relations, and marketing to help purchasers and lenders work through complicated questions related to acquisition, redevelopment, cleanup, job creation and construction, and to help local units of government reposition, assemble, and market their sites for interest by developers and other end users.
