Site Narrative:
Kelley Instruments, Inc. was historically located at 1024 (also 1004 and 1008) South Santa Fe Avenue in Wichita, Kansas. A radium dial shop Unified Focused Assessment (UFA) was conducted on the historical site in May of 2007.
The current Instruments, Inc. property is located at 4129 West May Street in Wichita, Sedgwick County, Kansas. KDHE conducted Unified Focused Assessments (UFA) at the current and former locations of Instruments, Inc. The former Instruments, Inc., property was determined to be impacted by radium-226 above the site-specific screening level.
The UFA at the current Instruments, Inc., property did not find any significant areas impacted by radium-226. While several volatile organic compounds (VOCs) were detected in the UFA groundwater samples, only 1,1-dichloroethylene (1,1-DCE) was detected above its MCL in any particular sample. 1,1-DCE was detected in GW-4 at a maximum of 16 micrograms per liter (g/L), above its MCL of 7 g/L. GW-4 was obtained adjacent to the Instruments, Inc. portion of the building. The two groundwater samples obtained during the UFA next to the adjacent Kelley Instruments, Inc., portion of the building (Kelley Instruments and Instruments, Inc., are adjacent within the same building) indicated much lower (2.3 g/L in GW-3 and not detected in GW-2) levels of 1,1-DCE and substantially lower levels of 1,1,1-trichloroethane (1,1,1-TCA), suggesting that the point of release initiated in the Instruments, Inc., portion of the building.
During the SE, an additional seven direct-push groundwater samples were collected near the UFA detections at the Instruments, Inc., portion of the building. 1,1,1-TCA was detected at 0.67 g/L, below its MCL of 200 g/L. 1,1-dichloroethane was detected at 0.58 g/L, below its Tier 2 RSK of 25 g/L. The elevated levels of 1,1,1-TCA and 1,1-DCE were not replicated during the SE sampling.
Since a significant release of VOCs to groundwater does not appear to be present at the Instruments, Inc., site, further site assessment consistent with the National Oil and Hazardous Substances Pollution Contingency Plan is not recommended.
