Site Background: This site, other Superfund sites, and non-Superfund sites contributed to widespread low-level groundwater contamination in the Biscayne Aquifer. The groundwater is contaminated with volatile organic compounds. The Biscayne Aquifer is considered a "sole source aquifer" and is the only source of drinking water for several counties, including Dade County. The contamination was significant enough to cause the shutdown of several wellfields including the wellfields at the Preston and Hialeah water treatment plants. Cleanup Progress: Construction Completed The widespread groundwater contamination was addressed by the installation of air stripping towers at the Preston and Hialeah water treatment plants and a wellfield protection plan implemented by Dade County. The air stripping towers have a capacity to treat almost 150 millions gallons per day and have been operational since September 1992. As a result, the previously impacted Preston and Hialeah wellfields were placed back into service. The groundwater treatment system provides the daily drinking water demands of almost one million people in northern Dade County. EPA reimbursed Dade County for the operation and maintenance of the air stripping towers for 10 years until September 2002. The air stripping towers were built by Dade County with oversight provided by the Army Corps of Engineers and EPA. Construction and operation costs have been shared by Dade County and EPA. |
