-  2.2.2 Issues

There is a known hex chrome groundwater plume that was attributed to the Hard Chrome facility. The plume location was last examined in 1993. When we started this project, we were told that the neighborhood surrounding the facility was on City water, but were not aware that the City does not require property owners to hookup to City water. We found that out recently. In light of that finding we examined the area around the 1993 plume location for drinking water wells – we identified 1 drinking water well (State then sampled it and it tested non-detect for hex chrome); and two other properties with no record of connection to City water (1 is abandoned, 1 does not use drinking water). Additionally, there are numerous properties that did not abandon their wells after they hooked up to City water.

We subsequently worked with state and local agencies to attempt to identify other potential wells in a larger area still being utilized in the area. On May 23, 2016, the City of Grand Rapids completed a review of an additional 935 parcels in the area, downgradient of the Hard Chrome facility, and did not identify any additional parcels with buildings that are not served by City water. The areas checked in both evaluations are depicted in a figure located in the documents section of the EPAOSC.ORG website for this response.  

We also requested that the state pre-remedial program assess this site for potential future action related to the groundwater plume.
