The 0153 Ground Water Contamination Site is an area of impacted ground water in the vicinity of the Riverside and White River well fields owned and operated by Citizens Water in Indianapolis, Indiana. Even though low levels of various chemicals have been detected in "raw", untreated ground water, the finished drinking water provided by Citizens Water is safe and meets all requirements of the Safe Drinking Water Act. The 0153 Ground Water Contamination Site area is generally 35th St. to the north, Holt Rd. to the west, Washington St. to the south, and Central Ave. to the east.
In early 2013, IDEM received notice from Citizens Energy Group that low levels of certain chemicals were being detected in the raw ground water located within the Riverside well field. In 2014, IDEM sampled the raw ground water from all 19 production wells located in the Riverside and White River well fields and found low levels of contamination in five of those wells. The contaminants of concern detected in the raw water of these five wells are trichloroethylene, cis-1, 2-dichloroethylene, vinyl chloride and 1,1,1-trichloroethane. These contaminants are man-made chemicals associated with historic manufacturing and dry cleaning processes. IDEM has begun investigation into the sources of the contamination and will be overseeing the investigation of sources of contamination and implementing a cleanup and monitoring plan.
In June 2017, the U.S. EPA deferred the technical and enforcement oversight of Site 0153 to the IDEM State Cleanup Program via a Memorandum of Agreement.
IDEM and U.S. EPA held a public meeting on March 25, 2017, at the Riverside Family Center Gymnasium.
IDEM has prepared an alternative proposed plan for the Riverside Ground Water Contamination site.
