Site Narrative:
The Bentley's Garment Care is located at 1110 N. 8th in Neodesha, KS, or in the SW 1/4 of Section 17, Township 30S, Range 16E, in Wilson County. The current occupant is Streaky Clean Laundry, which is a coin operated laundry mat on one side and a drycleaing drop off on the other. Drycleaning operations no longer exist at this facility.

Chlorinated solvent groundwater contamination was first identified in 1996 in association with the former British Petroleum/amoco Refinery site. Subsequently, KDHE conducted a SRE in May 1997. Three probes were advanced and chlorinated contamination was detected above EPA MCLs.

An ESA was completed in August 2002 and included 15 groundwater push probe samples and 27 passive soil gas devices. The ESA defined the plume and identified the source. In 2003, 10 monitoring wells were installed down gradient from the former Bentley's facility.

On March 16, 2004 a groundwater remediation system was installed. A lateral interceptor trench was installed south of the former Bentley's Garment Care on the south side of Tank Street. The trench is designed to draw in the contaminated groundwater, which is then pumped from the trench to a treatment system. The groundwater is treated by an Multi-stage Diffused Bubbler Aeration System (type of air stripper) and the treated water is discharged into the sanitary sewer. In July 2005, an anti-scaling chemical feed system was added to inhibit mineral scaling within the air stripper. The system contains a GAC drum for treating the effluent air from the stripper. The system has effectively prevented the down gradient migration of PCE in the groundwater.

A Source Investigation was conducted in December 2007 to delineate the extent of chlorinated solvent in the soil. Soil was collected from three intervals at 12 locations using direct push technology. Chlorinated concentrations exceeded the KDHE Risk Based Standards in 4 of 12 locations. Five more additional soil borings were conducted in December 2008 to further define the extent of the soil contamination within the foot print of the building. A sedimet sample was collected from the sediment basin on the north side of the facility. PCE was detected 1,370,000 ug/kg in the sediment sample. A remediation design is currently in progress to address the soil contamination beneath the former facility. The design entails a digout to remove the contaminated soil. The digout is anticipated to begin in late summer of 2009.

In June 2009, the City of Neodesha began a project to demolish the City pool and construct a ball field on the property. The project entails moving the groundwater treatment system and subsequent repiping to the sump in the trench and to the sewer. In addition, five monitoring wells are to be abandoned and two replacement wells installed. The transition from the pool to ball field is anticipated to be completed by the end of July 2009.

Semi-annual groundwater sampling is on-going and occurs in March and September. In May, it was found that the electrical panel for the remedial system was malfunctioning. Due to the advanced deterioration of the remedial system it was decided to replace the entire system. The new air stripper installed in 2017 is running without issue and is effectively addressing groundwater contamination. LTM and OM&M continues.
