The primary goals of the Remedial Section are to protect and preserve one of the most important natural resources of our state - our water supply, both groundwater and surface water, and to protect the human health and welfare of the citizens of Kansas, both current and future generations from environmental contamination.

KDHE Seeks Public Comments on Proposed Cleanup at 31st and Clifton ERA Site - Wichita, Kansas
The Kansas Department of Health and Environment (KDHE) is asking for public comments regarding a proposal to address environmental contamination at the 31st & Clifton Site located at 31st Street South and Clifton Avenue in Wichita, Kansas.

A draft Agency Decision Statement (ADS) document that outlines a proposal for cleanup is available for public review at the Wichita Library located at 223 S. Main, Wichita, KS and at the Curtis State Office Building, 1000 SW. Jackson in Topeka, Kansas. The Draft ADS and other pertinent information is available at the link listed below. Additional information is available at the Identified Sites List. Links to copies of the Draft Agency Decision Statement and the Corrective Action Study are below.

Public comments can be submitted in writing to: Margaret Townsend, Professional Geologist, KDHE Bureau of Environmental Remediation, 1000 SW Jackson St., Suite 410, Topeka, KS 66612-1367. Comments will be accepted until December 5, 2014.

Schilling Air Force Base
The former Schilling Air Force Base is a FUDS located in southwest Salina, Kansas. The base was originally built as the Smoky Hill Army Airfield in 1942. The base was deactivated in the 1960's; it is now used for the Salina Regional Airport and industrial, aviation, military, and educational facilities. The Salina Airport Authority (SAA), Kansas Department of Health and Environment (KDHE), the US Environmental Protection Agency (EPA), and the US Army Corps of Engineers (USACE) have conducted numerous environmental investigations and some limited remedial actions at the Schilling AFB Site since the mid-1990's.

Risk-based Standards for Kansas Manual Updated With New Tables
KDHE/BER has updated the Appendices of the 2010 RSK Manual. The complete manual may be downloaded at the above link. Any questions regarding these changes and their effects on the management of a contaminated site may be directed to the KDHE project manager.

Elevator Groundwater Containment System Constructed in Salina
Features of the groundwater containment system.

The former Bunge grain elevator is located at 1112 N. Halstead road, approximately a mile and a half southwest of the I-70 and I-135 interchange in Salina. Soil and groundwater is contaminated with carbon tetrachloride and chloroform, a degradation product of carbon tetrachloride. These chemicals are associated with grain fumigants formerly used and stored at the facility. Investigations identified release(s) of grain fumigant in the vicinity of a former above-ground storage tank and groundwater contamination had migrated beyond the property boundaries. Some private wells were contaminated with carbon tetrachloride and chloroform. Impacted residences have been connected to a rural water supply.

An air stripper inside the treatment building.A half mile long Groundwater Containment System (GCS) was completed in June 2013 as an interim remedial measure to capture contaminated groundwater migrating from the grain elevator. The objective of the GCS is to maintain hydraulic control of the groundwater plume in the vicinity of the down-gradient property boundary through active extraction, treatment, and discharge.

The GCS is designed control groundwater migration by pumping groundwater from 15 extraction wells (blue dots) and transferring it to an air stripper located inside the groundwater treatment building (orange square). The air stripper consists of six perforated trays creating turbulent flow and a high air-to-liquid surface area for efficient removal of volatile organic compounds. The treated groundwater is then discharged to Mulberry Creek via subsurface piping and a constructed outfall.

The GCS has operated continuously since starting up in June 2013. Initial performance data indicate the system successfully depresses the groundwater surface, resulting in a significant zone of containment along the southern property boundary and preventing off-site migration of contaminated groundwater.
