The results of the laboratory analyses and other groundwater data are then forwarded to a separate consultant, also under an existing contract, to incorporate into quarterly groundwater monitoring reports for submittal to the Regional Water Quality Control Board (RWQCB). The majority of the PCE sites' wells are located in the City right-of-way.
