Battle Mountain Resources—San Luis SL-SOP-Groundwater Well Decommissioning <br /> STANDARD OPERATING PROCEDURES REVISION: 0 -May 6, 2019 <br /> decommissioned. Historical groundwater quality data is linked to monitoring well locations so <br /> when a well is decommissioned, existing GIS data must be updated to reflect that fact but the <br /> coordinate location in the GIS database should not be eliminated. A metal detector may not be <br /> able to detect a deeply buried marker so if this locator is important for future utility runs or <br /> foundations, a map should be submitted to the property owner and the town engineer showing <br /> the decommissioned well locations. Global Positioning System (GPS) coordinates should be <br /> indicated on this map. Lastly, whatever documentation is produced should be provided to the <br /> property owner and all other parties involved. <br /> 11. FIELD OVERSIGHT <br /> Over-drilling requires careful observation to detect whether the drill has wandered off the well. <br /> Grout preparation and tremie work should be carefully observed. The successful <br /> implementation of a decommissioning work plan depends upon proper direction, observation <br /> and oversight. Methods to be employed must be clearly worked through and all parties must <br /> understand what they have to do before going into the field. Flexibility is allowed where <br /> necessary but the work effort must be thorough and effective to protect our groundwater. <br /> 12. REFERENCES <br /> 12.1.
