Document, Report, or Work plan Review - other |
Reviewed UST closure report. DRO soil contamination exceeding ADEC cleanup standards exists in excavation and stockpile. Additional assessment, corrective action & remediation required. Sent e-mail to ADOT to see if any additional work may have been done since 2000. |

Update or Other Action |
DOT has not conducted any further work since UST removal in 2000. A letter was sent requiring additional assessment and corrective action work be conducted to bring the site to closure. The contaminated soil stockpile must remain covered to prevent spread of contamination. |

Update or Other Action |
Discuss preliminary site findings with Mike Reiser (SLR). Test pits and holes have not found the contamination at levels reported in the R&M report. At a loss to explain the differences. Installation of MWs will provide additional information on soil & GW contamination. Stockpile will be sampled. Based on assessment and stockpile sampling results, the remediation contractor may not be needed. Decision will be made when more information is available. |

Document, Report, or Work plan Review - other |
Sample results from MW-1 in August 2014 showed benzene (0.00505 mg/L) and DRO (2.86 mg/L)exceeding ADEC Table C cleanup levels and showing decreasing concentrations since 2006. Contamination at the site is not causing risk to human health or the environment. I can recommend decommissioning the monitoring wells and closing the site. |
