Drycleaner Site Profiles
Wright's Dry Cleaners, Winter Haven, Florida
Description
|
This is an active drycleaning facility that has been operating since 1975. The facility uses both PCE and petroleum drycleaning solvents. A UST where No. 2 fuel oil was formerly stored has been abandoned. The facility is served by a septic tank/drainfield. The facility is located approximately 450 feet upgradient of a small sinkhole lake. Contaminant sources at the site include soils beneath the biulding floor slab near the drycleaning machine and the septic tank/drainfield. |

Introduction of air into air inlet wells installed in dead spaces will increase the pressure gradient between SVE wells and and air inlet wells, enhancing air movement towards SVE wells. The presence of fine silt interbed in the unsaturated zone acted to retain contaminants and resulted in a rebound in contaminant influent concentrations after two system shutdown periods. |
