2.1.1 Narrative
EPA received a request for assistance from Mecklenburg County Groundwater and Wastewater Services. Mecklenburg County discovered the presence of tetrachloroethylene PCE in a private water supply (well) above the Removal Action Level (RAL) of 12 parts per billion (ppb) on Bennett Street in Charlotte, NC. Samples collected by Mecklenburg County on May 7, 2010 documented the presence of PCE at 17 ppb. EPA provided bottled water to the resident and will connect the home to a municipal water line that is located at the street. EPA will also disconnect the contaminated private well and permanently close the well to prevent the possibility of future cross-contamination.
On June 10, 2010 Mecklenburg County Groundwater and Wastewater Services notified EPA of another residential well contaminated with PCE above EPA Maximum Contaminate Level (MCL) of five ppb and the RAL. PCE was detected at 24 ppb in samples taken on May 26, 2010 by Mecklenburg County. The residence is located on Argyle Drive in Charlotte, NC. The source of PCE contamination in the Bennett Street and Argyle Drive wells is unknown. EPA is providing bottled water to the impacted residence and will connect the home to a municipal water line and permanently close the well.
