29th and Grove Site


The 29th and Grove Site (Site) is located along the northern part of a Union Pacific Railroad (UP) rail yard south of the K-96 Highway, between Highway I-135 and Grove Street, in Wichita, Sedgwick County, Kansas. Land use in the immediate vicinity of the northern rail yard consists of rail transportation, recreation, and military land-use categories. The K-96 Lake Park is located to the north of the railroad tracks. The Heartland Preparedness Center is located south of the railroad tracks. Land use farther to the south is primarily residential and commercial.

The contaminants of concern (COCs) are trichloroethene (TCE) and associated degradation compounds including 1,2-dichoroethene, 1,1-dichlorothene, and vinyl chloride. TCE is a solvent commonly used for metal degreasing. Contamination from the Site was first discovered during investigations conducted in advance of redevelopment of the 21st Street corridor between I-135 and Grove Street.

In 1999, KDHE and Union Pacific Rail Road (UP) executed an Interim Agreement for a Preliminary Investigation (PI) to evaluate whether a release of  trichloroethylene (TCE) had occurred on the UP rail yard right-of-way.  Detections of TCE in soil and groundwater at the rail yard confirmed a release had occurred on the rail yard property in the past. TCE is present in the soil at the rail yard at concentrations above the Tier 2 Risk-based Standards for Kansas (RSK) level of 84.2 micrograms per kilogram. TCE is present in groundwater at concentrations above the Tier 2 RSK level of 5 micrograms per liter.

In 2002, UP entered into a Consent Order with KDHE to conduct a Remedial Investigation to determine the nature and extent of contamination and a Feasibility Study to evaluate remedial alternatives that could be used for cleanup. The Remedial Investigation was completed in 2006 and determined the plume of contaminated groundwater extended from the UP rail yard to the south to Murdock Avenue.
