Look at this latest report on a Kansas missile site 12 water after 35 years. TCE, PCE and Arsenic in the water way above Government limits. What does that tell you about what we were drinking while on duty! Another smoking gun!

Site Narrative:
Titan II Missile Site (MS) 12 was one of 18 ICBM facilities under the control of the 381st Strategic Missile Wing based at McConnell Air Force Base in Wichita, Kansas. The property was purchased by the U.S. Government in 1960, and construction of the facility began in 1961. The site was operational in 1963. In 1986 the site was dismantled and deactivated in accordance with the SALT Treaty.
MS12 is located in south-central KS within 35 miles of McConnell AFB. The site is about 1.5 miles south of Conway Springs, KS on Hwy-49. The USAF owns & maintains the site. No structures remain except remnants of concreate pads from various onsite operations. The site is primarily bordered by agricultural land on all sides. A residence is located about 450 feet to the west-southwest of the western site boundary.
A 30 - 40 gallon spill of hydraulic oil into the silo sump was recorded in March 1978. No other findings of environmental releases were noted.
In 1999, a passive soil gas survey & site reconnaissance was conducted as Phase I of the Remedial Investigation (RI). 25 soil gas modules were set & were analyzed for VOCs & SVOCs. All reported detections were at or just above the reporting limit; the concentrations were very low.
In 2000, Phase II of the RI included installing & sampling 1 shallow monitoring well (MW-1S) for soil & groundwater (GW) samples. Drinking water samples were also collected from nearby private wells. Soil was collected from 0-2' & 6-8' & analyzed for VOCs; none were detected. GW was analyzed for VOCs & perchlorate; TCE was detected at 1,990 ug/L; PCE & carbon tetrachloride were detected at lower levels.
Phase III was completed in 2002. Five shallow MWs (MW-2S - MW-6S) were installed. 6 of each surface (0-2') & subsurface (interval just above bedrock) soil samples were collected and analyzed for VOCs; none were detected. 1 deep MW was also installed (MW-1D). 3 rounds of GW samples were collected from the 7 wells. TCE was found at MW-1S (440-570 ug/L) & at MW-2S - MW-5S at concentrations from 3-7 ug/L.
In 2004, Phase IV was completed. A geophysical survey, subsurface soil sampling, installation of 3 shallow MWs (MW-7S - MW-9S), GW samples were collected, & aquifer testing was performed. The geophysical survey showed anomalies at the 3 former UST locations; borings were installed & no USTs were found. A subsurface soil sample was collected from each boring. Another soil boring was installed near the cooling tower/transformer pit outfall. Soil samples were analyzed for VOCs; none were detected. All 10 MWs were analyzed for VOCs. TCE was found at MW-1S (580 ug/L), 9S (360 ug/L), 7S (26 ug/L), 8S (8.1 ug/L), 2S (9.1 ug/L), 4S (8.7 ug/L), & 5S (34 ug/L).
Phase V of the RI included an additional round of GW sampling in 2009, along with surface & subsurface soil sampling, installation of 6 shallow temporary wells & two shallow bedrock MWs (MW-10S & MW-11S) in 2010. MWs 1S, 5S, & 9S were analyzed for VOCs, SVOCs, metals, PCBs, & hydrazine; only inorganics were detected. Arsenic (ug/L) exceeded MCL (10) in all 3 wells (16-22). TCE (ug/L) was detected in 7S (10), 1S (830), 8S (3.4), 9S (270), 2S (3.5), 4S (3.9), & 5S (23). PCE (ug/L) was detected in 1S (11) & 9S (3.8).
A 2010-2011 Treatability Study (TS) evaluating in-situ chemical oxidation (ISCO) demonstrated that injections of sodium permanganate is capable of degrading PCE and TCE in shallow bedrock groundwater to below USEPA MCLs.
A Final Record of Decision (ROD) for in-situ chemical oxidation (ISCO) at MS12 was approved by KDHE in November 2017. ISCO, using modified Fenton's reagent (MFR), will be performed to degrade PCE and TCE in groundwater.
