Site Narrative:
A KDHE Site Reconnaissance and Evaluation Investigation conducted in 1996 and a Preliminary Investigation Report completed in 2000 confirmed contamination was present at the site located in the NW portion of the City of Marysville. The site is situated with residential districts on the south and east, and agricultural land on the north and west borders. Historical operations consisited of fueling and servicing locomotives. The contaminants of concern (COC's) in soils exceeding the soil to groundwater (GW) pathway Risk-based Standards of Kansas (RSK) levels include total petroleum hydrocarbons (TPH) within the diesel range of organics (DRO) and the gasoline range of organics (GRO), napthalene, 1,1,2,2-tetrachloroethane, 1,1,2-trichloroethane, and 1,2,3-trichloropropane. Maximum TPH DRO concentration in soil from GB-42 identified 27,900 milligrams per kilogram (mg/Kg) exceeding the soil pathway of 2000mg/Kg. GW at the site is found as shallow as 9 feet below the ground surface (bgs) and as deep as 22 feet bgs. Shale bedrock was reached at 36.5 feet bgs at SB-13. The COC’s for this property in GW exceeding Maximum Contaminant Levels (MCLs) or GW pathway RSKs include TPH-DRO & GRO, napthalene, 2-methylnaphthalene, fluroene, benzo(a)pyrene, benzene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene. Maximum TPH-DRO concentration in GW from MW #10 was 2,850 milligrams per liter (mg/L) exceeding the GW pathway of 0.5 mg/L .  
Union Pacific Railroad submitted an application to the Voluntary Cleanup and Property Redevelopment Program (VCPRP) on August 14, 2002. The property was accepted into the VCPRP on November 25, 2002. The Voluntary Cleanup Investigation (VCI) Work Plan was approved by KDHE and the initial phase of investigation took place in 2003.  
A VCI report was completed in March 2007. Results of the investigation indicated that free product was/is present near the former refueling (FR) facility on the property from north to south, in MW #10 (between 2005-2008), MW #15, MW #5, MW #16, and GB-5 - SW of MW #16. Also MW #20 located south of the FR area reported measurable light non-aqueous phase liquid (LNAPL) in 2011. Petroleum hydrocarbon contamination was present in soil and GW at the FR area. Chlorinated solvent contamination was also detected in soil at this FR area, however, there were no indications of chlorinated solvent impacts in GW.  
Further assessment included collecting data for reservior characterization. In 2008 a pilot study was initiated to try to address the free product issue. High vacuum extraction was utilized to try to remove the free product as the GW monitoring network was expanded with the addition of MWs #15 through #20.  
A Voluntary Cleanup (VC) Proposal was submitted in November of 2010. The VC Proposal would address LNAPL impacted soil via excavation and proper disposal at a landfill, was conditionally approved in March 2011. Additional focused delineation was conducted in November of 2011 and during the spring of 2012 to better define TPH DRO, TPH GRO, and VOC soil impacts. A Pilot Test (PT) involving in situ chemical soil blending was approved in August 2014 on two locations at the site to remediate soil TPH and VOC impacts. GW monitoring continues and a Pilot Test Summary Report recorded the success of the in situ soil blending concerning VOCs.  
A VC Plan was received in August noting the remediation of VOC impacts in soil and as a contingency the TPH DRO and GRO areas will be excavated and land-farmed. Initiation of the VC Plan is anticipated in fall of 2015.  
Tier III WP approved in Spring 2016. Tier III field activities conducted in Summer 2016. Awaiting report of results.  
Semi-annual GWM continues. Tier III completed and Tier III values approved for TPH. IRM planning for source removal via excavation underway as of Fall 2018.
