Superfund Sites in Reuse in North Dakota

The Arsenic Trioxide Superfund site spans 26 townships and about 940 square miles of rural farmland in Ransom, Richland and Sargent counties in southeastern North Dakota. Because of massive grasshopper infestations during the early 1900s, the U.S. Department of Agriculture supplied the state of North Dakota with arsenic-laced grasshopper bait. Farmers and landowners applied the bait to fields. They also buried leftover bait in unlined pits. Over time, arsenic contaminated soils and groundwater. EPA added the site to the National Priorities List (NPL) in 1983. EPA initially supplied residents with water treatment units and covered a former bait mixing area. EPA, the North Dakota Department of Health (NDDH) and the Southeast Water Users District (SEWUD) upgraded three water treatment plants, built new water storage reservoirs and supply wells, and installed 300 miles of water distribution pipeline. EPA deleted the site from the NPL in 1996. In 2003, EPA found that more cleanup efforts were necessary because cleanup levels for arsenic had become more stringent. The communities of Wyndmere and Hankinson connected to the SEWUD rural water supply system. Additional efforts included water treatment plant expansion, upgraded water supply wells and water reservoirs, and connection of more rural households to public water. To reduce on-going maintenance costs, improve energy efficiency and ensure continued groundwater treatment and distribution, even during power outages, SEWUD installed a geothermal heating and cooling system and an emergency back-up generator to power its headquarters building where it manages remote sensing of the system. This cost-effective approach reduces the facility’s use of fossil fuels and lowers operation and maintenance costs while providing for continued operation during power outages. As part of the site remedy remaining protective of human health and the environment over the long term, institutional controls inform land users of potential arsenic contamination. Primary land uses on site are residential and agricultural uses; areas include unaltered prairie land and farmland. Many residents continue to use groundwater safely for livestock consumption and irrigation. SEWUD operates on site.

The 26-acre Minot Landfill Superfund site is in Minot, North Dakota. The landfill received municipal and industrial wastes from 1961 to 1971. Hazardous chemicals contaminated groundwater, surface water, soil, sediment and air. EPA added the site to the National Priorities List (NPL) in 1989. The city of Minot capped the landfill waste and conducted other necessary improvements under a consent decree with EPA and the State of North Dakota. After cleanup, EPA took the site off the NPL in 1997. The site is covered in grass, which is harvested twice a year for hay. City workers stockpile snow at the site during large snow removal events. The Minot Fire Department also built a burn tower at the site and uses the area for firefighter training. The city of Minot and the Minot Park District have proposed to reuse parts of the site as a public park with cross-country trails, mountain-bike trails and a disc golf course. The city of Minot and the Minot Park District are working with EPA and the North Dakota Department of Environmental Quality to ensure the compatibility of planned recreational reuses with the site’s remedy.
