The site is currently not in use. All above-grade former manufacturing plant structures were removed from the site.

The majority of the site is covered with asphalt surfacing with limited areas covered by concrete. Soil and groundwater contamination includes coal-tar contaminated materials as a result of historical manufacturing gas plant operations. There are two buildings on site that were formerly used for storage and operations, and a communications tower. They include the U. The area provides protected habitat for migrating birds, whitetail deer, burrowing owls and prairie dogs.

A racetrack, campground and golf course are also located on site. The City uses the Second Street sub-site as a storage lot. As of December , EPA had data on 43 on-site businesses. Superfund site is in downtown Norfolk, Madison County, Nebraska.

A manufactured gas plant operated at the site from about to Waste products from the manufactured gas process are present in soil and groundwater at the site. Two public services energy utilities own parts of the site. The Nebraska Public Power District portion of the site is a fenced gravel lot. The Lindsay Manufacturing Co. In , LMC began operating on site.

LMC currently makes galvanized irrigation sprinkler equipment on site. Between and , the facility discharged process wastes into an unlined lagoon on site. Use of the lagoon ceased in , when monitoring identified contamination. Improper waste management also resulted in groundwater contamination beneath the facility. As a result, the facility began treating the groundwater. EPA expanded the cleanup to include area soil.

Today, both LMC and the farmer who owned the wells affected by contamination are benefiting from this unique cleanup approach. As of December , EPA had data on 4 on-site businesses. Electronics manufacturing, grain storage and dry-cleaning operations contaminated groundwater with volatile organic compounds VOCs and solvents. For the first subsite, the long-term remedy included groundwater extraction and treatment, institutional controls to protect the public water supply, and monitoring of natural processes to clean up groundwater.

Groundwater extraction and treatment ended in For the second subsite, the long-term remedy included the treatment of contaminated soil and groundwater. In , EPA finished demolishing the former dry cleaners building, excavating contaminated soils, replacing excavated areas with clean soils, and regrading the site.

Long-term cleanup, operation and maintenance activities, and monitoring are ongoing. The area above the groundwater plume includes a mixture of residential, commercial and industrial properties. These areas remain in continued use. The site consists of a groundwater plume along West Reichmuth Road that is about 2. No source has yet been identified. The plume contains volatile organic compounds VOCs.

Homes with private wells where contaminants were found either connected to the city of Valley public water supply or have whole-house filtration systems. EPA did a vapor intrusion investigation in The area above the groundwater plume includes residential, commercial and industrial properties. The Site covers approximately 27 acres in downtown Omaha. From the early s to , two lead smelting plants operated on the banks of the Missouri River.

The plant smokestacks released lead and other heavy metals into the air. The metals then settled out of the air and contaminated the ground across the Site.

Regarding chemical oxidation, seven rounds of injections have been conducted in various places within the contaminant plume on a semiannual basis, starting in January through October No further chemical oxidation injections are planned at this time. Currently, EPA is in the process of reviewing all of the site data to determine what response actions will be necessary in the future.

EPA is also in the process of conducting vapor intrusion sampling. They found these additional actions need to be taken to ensure long-term protectiveness of the site:.

With the exception of vapor intrusion sampling, which is not complete and has not been included in the final assessment of the five-year review, the site remedy is currently determined to be protective of human health and the environment. The final report, dated July 2, , is available at the site information repositories and on the EPA Region 7 website at:.

Using this approach, parcels with greatest potential for impervious surface area pay a higher stormwater utility fee than parcels with less potential impervious surface area. The following sites provide information about runoff pollution sources and the necessary steps needed to avoid the spilling of these pollutants into our streams and rivers:.
