ChemTrack was contracted by the Alaska District to complete an extensive inventory of groundwater monitoring wells that had been installed throughout the years 1998 to 2014. Over time, wells had been destroyed, damaged, and/or removed, and there was no current documentation or survey of the wells.
The scope of work included an in-depth inventory of the monitoring wells by visual search, traversing through dense forest in the Kodiak wilderness. A total of 136 wells was physically located and inspected, cleared of vegetation, labeled, and marked with high visibility flagging. Samples were collected from 22 of these wells and analyzed for total lead, hexavalent chromium, and diesel range organics. Soil and sediment samples were collected at a former battery acid storage site for total lead analysis. Sample locations, and all wells that were physically located, were surveyed following USACE requirements. A final report was written with the sample results, and a detailed well inventory log was provided including well locations, description, condition, and maintenance required.
