Update or Other Action |
One UST was found to contain fluid, presumably water & residual fuel. It will be pumped out prior to UST removal. More contaminated soil was found than expected. 50yds3 will be stored in supersacks as planned. The rest will be placed on a liner and covered for the winter, pending analytical data to determine disposal options. |

Document, Report, or Work plan Review - other |
Received and reviewed the Groundwater Monitoring Report prepared by term contractor Clarus Technologies, LLC, dated June 2008. Approximately 100 cubic yards of GRO and DRO contaminated soil was landspread onsite. Five GW monitoring wells were sampled and MW-5 exceeded ADEC GW cleanup levels for DRO. All other MWs met ADEC groundwater cleanup levels. MW-5 is the downgradient MW and should be resampled again during the 2009 field season. The landspread soils could also be resampled at that time to see if the GRO and DRO contaminant concentrations meet the ADEC soil cleanup levels. |

Site Visit |
On this day, the CSP observed soil and groundwater sampling at this site. Monitoring Well MW5 was purged and sampled. A petroleum odor was noted during the purging activities and a sheen was observed while filling the sample jars. MW5 purged dry while filling the final sample jar. In addition to sampling MW5, the formerly land spread soils were screened and sampled. Because the ADOT had grated the entire area, the edges of the former land spread soils were not located. Four screening and one analytical sample were collected from the approximate location of land spread soils. All soil and groundwater samples were submitted for GRO, DRO, RRO, and BTEX. Analytical results were received on June 9, 2014. The water sample exhibited a concentration of DRO at 10.8 mg/L; which exceeds the ADEC cleanup criterion of 1.5 mg/L. The soil sample did not exhibit any contaminants exceeding ADEC cleanup levels. |
