|The site was accepted into Dry Cleaning Trust Fund and prioritized for fund expenditures in 2011. On January 24, 2017, KDHE and EMR conducted a site visit. Soil gas modules were installed the next day to assess potential areas of soil contamination inside and outside the building.
Data from the soil gas modules was used in conjunction with other information to determine the best locations for soil and groundwater probes. Initial delineation work was completed the week of April 17, 2017. Additional delineation work will be completed the week of July 25, 2017. Two private wells were sampled along Seneca street with one result indicating contamination above the EPA MCL for cis 1,2-DCE. After these wells were sampled, an additional 192 wells were sampled to determine the extent of the contamination. With this information, KDHE developed a memorandum of agreement with the City of Haysville to connect 227 properties in the area of identified contamination. Water mains needed for private connections have been installed and the connections are being made. 210 properties have accepted the offer to be connected to the water system.
With the extent known, 30 monitoring wells were placed around and inside the contaminant plume to monitor for any change to the plume dynamics. Groundwater sampling is taking place on a quarterly basis.
