Site Narrative:
The Lincoln Grain/Garvey Grain Site (“Site”), also referred to as the Atchison Elevator, is located along U.S. Highway 59 West near Atchison, Atchison County, Kansas. The Site is in a rural area approximately five miles southwest of downtown Atchison, Kansas.

The Site has been operated as a grain elevator since approximately 1959. Site owners/operators prior to Continental Grain Company used a 5,000 gallon above ground storage tank (AST) of carbon tetrachloride (CT) based fumigant for grain fumigation purposes. Piping from the AST ran underground for approximately 70 feet to the elevator silos from the AST that was located on the north side of the elevators between the maintenance shop and the silos. There are no engineering drawings available regarding the facility construction, piping layout or piping bedding. Since the actual dates of the fumigant usage are undetermined, usage is expected to have occurred sometime after 1959 (facility development) until 1986 when CT was taken off the market.

There is a footing drain at the base of the grain elevator and water collected from the drain is pumped to a tank referred to as the cistern. CT and other contaminants of concern (COCs) have historically been detected in the cistern water, so an air stripper was installed downstream of the cistern, which gravity overflows to the surface discharge drainage swale system at the elevator. The discharge is regulated under an NPDES permit limits carbon tetrachloride (0.005 milligrams per liter (mg/L)) and methylene chloride (0.005 mg/L).

Between 1990 and 1999, Continental Grain Co. owned and operated the facility. The Site was discovered in 1999 during a due diligence transaction which identified elevated concentrations of carbon tetrachloride and carbon disulfide in groundwater at the Site. An Administrative Settlement Agreement and Consent Order (Case No. 05-E-0062) between KDHE and ContiGroup Companies Inc. was executed in November 2005 to investigate contamination at the Site and to implement an Interim Remedial Measure (IRM) in the source area and complete a Comprehensive Investigation and Corrective Action Study (CI/CAS).

Based on the results of various investigations at the Site, including the CI, the initial CT mass in soil was estimated at 3,220 pounds (lbs). The maximum CT concentration detected in soil was 10,404 mg/kg, and the maximum CT concentration detected in groundwater was 640 mg/L. An area of approximately 2,720 square feet was identified as the carbon tetrachloride source area in soil. The vertical extent includes COCs in soil range from 4 to 49 feet (ft) below ground surface (bgs).

In September 2010, KDHE approved the Interim Remedial Measures Design/Remedial Action Work Plan (Work Plan). The Work Plan called for source area removal of CT and chloroform (CF) primarily through hydrolysis at elevated temperatures using electrical resistance heating (ERH). The ERH treatment system was installed within the source area and operated from May 2011 to March 2012. An area of approximately 2,720 square feet was treated with ERH. Reductions of CT exceeding 99 percent were achieved in both the soil and groundwater within the source area during the interim measure.

A Corrective Action Study selecting ERH as the final remedy at the Site was approved in August 2014, with a remedial action effectiveness report to follow every two years for a six-year period. The first remedial action effectiveness report was received in January 2017, and the second report was received October 2019. Groundwater monitoring is conducted on a quarterly basis to monitor the effectiveness of ERH at this Site. Groundwater monitoring data showed fluctuations within the source area as the soil temperature cools from the heating.

Currently, KDHE is working on a Corrective Action Decision in response to the conclusion of the remedial action effectiveness reporting period.
