Toeroek supports EPA Region 2, 4, 5 and 6 under our REPA contracts to provide defensible environmental data for potential enforcement actions, including preparation of work plans, including uniform federal policy quality assurance project plans (UFP-QAPP), collection of samples from environmental media, including groundwater, surface and subsurface soils, sediment and surface water, and soil-gas, management and disposal of investigation-derived waste (IDW), analytical testing of samples, data validation and management, and data analysis and findings included in the final data report. We also install and develop groundwater monitoring wells, as well as re-develop older monitoring wells, and have experienced staff to log boreholes and ensure that all samples are collected appropriately and documentation and chain-of-custody is maintained for legally defensible data. Toeroek uses agile project management practices triad systematic project planning principles working interactively with our client to optimize projects in concert with use of work plan addenda referencing established work plan documents, such as an approved QAPP.
