Himco Dump is a closed landfill covering about 60 acres in Elkhart at County Road 10 and the Nappanee Street Extension. The dump was privately owned and operated by Himco Waste-Away Services Inc. between 1960 and 1976. The area was initially a mixture of marsh and grassland with no natural barriers that could block the release of contaminated ground water or gas. An estimated two-thirds of the waste in the landfill is calcium sulfate from Miles Laboratories, (now Bayer Healthcare, LLC). As many as 360 tons per day were dumped over an unknown period. Other waste accepted included household and commercial refuse, construction and demolition debris, and industrial and medical waste. In 1976, the landfill was closed and covered with 1 foot of sand over a layer of calcium sulfate. The area bordering the southern perimeter of the landfill consists of construction rubble.

Site Updates

March 2015

EPA is doing a status review of the cleanup. This type of review is required at least every five years where the cleanup is complete but hazardous waste remains managed on-site. These reviews are done to ensure that the cleanup continues to protect people and the environment. This is the first five-year review for this site.
Contact the site community involvement coordinator and/or the remedial project manager to provide input on this review process.

The review will include:

A report, which will be available by March 2016, will detail the site's progress.

January 2013

Additional soil gas probes were installed at the landfill in December 2012 to better define the source of elevated landfill gas levels detected in October 2012 in certain locations in the landfill. If landfill gas levels have been found to be above established action levels, remedial measures to address it will be undertaken to reduce it to acceptable levels. While landfill gas levels are elevated at certain locations in the landfill, measurements taken near the border with residential homes indicated levels are below the action levels.

March 2011

Cleanup at the Himco Dump Superfund Site in Elkhart, Indiana continues with work on the former landfill and construction debris area commencing March 21, 2011. This work, which is expected to take about 18 months to complete, will require enhancing the existing cover in the landfill and installation of a landfill gas management system. Removal and disposal of contaminated soil in the adjacent construction debris area, which affects parts of backyards of 5-7 homes located next to the landfill, will also be undertaken. A long-term groundwater monitoring program has also been instituted whereby groundwater within and around the site will be monitored for a minimum of 10 years to ensure contaminants are no longer a threat to the community. Previously, the responsible party for the site provided alternate drinking water to residents living adjacent to the site, along with abandonment of drinking water wells in those homes.

Upon completion, EPA will review the effectiveness of the remedy every five years to ensure the remedy continues to be protective.
