Conduct monitoring and reporting for two sample events annually at the Site o Seven groundwater monitoring wells (three on-site and four off-site) sampled o Sampling must occur during the months of February and September o Accredited lab must run analysis o Groundwater Monitoring Report and correct data format must be uploaded to Geotracker Review water quality monitoring data and previous monitoring reports from 2019 to present to determine next actions with meeting the Board’s requests Evaluate and implement if additional monitoring of 12 private wells within 4,000 feet of the Site are feasible and required based on regional water quality and groundwater gradients and directional flow Create and submit to the Board an initial work plan to characterize the extent of groundwater contamination originating from the Site with a focus on conducting a groundwater survey consisting of grabbing groundwater sample collection in the area Evaluate, determine, and construct additional monitoring wells at varying distances and depths below grade which would aid in characterizing any spread of contamination from the Site Conduct monitoring and reporting of the newly constructed 3-4 monitoring wells during the two sample events annually at the Site Create and submit to the Board 2 future updated work plans for additional groundwater investigations parameters on/off Site that determines the contaminant plume migration and evaluation of any future impact to local water sources (groundwater and surface water) Meet all regulatory timelines for submittal of reports, plans, and communication with the Board and prior review with City staff before submittal to Geotracker
