monitoring wells located on privately owned parcels,access was requested through written agreements with the property owners.The City sent letters to these property owners on September 1, 2015,and followed up with letters again to the non-responsive parties on September 24, 2015. As a result of these efforts,approximately 88-percent of the monitoring wells located on privately owned parcels were made accessible to the City; copies of the signed access agreements are provided in Appendix C.The remaining property owners denied access or did not respond,making the wells inaccessible to the City. One property owner did not grant access until after completion of the well site visits, and there was insufficient time to visit and assess the conditions of known wells on their property.Two of the wells (CLSP-2 and CLSP-8)were visited and sampled in 2013, CLSP-2 was found damaged and CLSP-8 was functional.Two additional wells (MW-N1 and MW-N2) have not been visited since 2007 and their current status is unknown.A field reconnaissance to assess the status of these wells will be planned and the results included as an addendum to the planned Well Abandonment Report. Copies of available well installation and destruction permits (where applicable) for the monitoring wells listed in Table 1 are provided in Appendix D.A file search was completed in an effort to obtain these permits,and a public records request was submitted to San Joaquin County Environmental Health Department in an attempt to obtain permits not on file. Detailed monitoring well inventory sheets for existing wells can be found in Appendix E.Table 2 provides the as-built characteristics for all existing monitoring wells,and Table 3 summarizes recommended well head protection improvements; the Well head Protection Improvements Plan (Appendix F) provides specifies details for these improvements. Future well inspection and maintenance activities shall be made in accordance with the Inspection and Maintenance Plan (Appendix B). The WDRs slated six monitoring wells for abandonment to simplify the monitoring network.'Table 4 and Figure 2 summarize the proposed monitoring wells to abandon and five additional monitoring wells recommended for abandonment because they were damaged or yielded insufficient water quantities for sampling. Field reconnaissance revealed that grading activities around one of the original six wells (CLSP-3) increased land surface level adjacent to the well,and excavation will be required to expose the buried concrete well pad in order to properly abandon the well. Because the well is accessible to the City,it is secure and functional,provides water level data adjacent to the San Joaquin River, and there is uncertainty in the timing and extent of future land use plans for the site,the City recommends keeping CLSP-3 as an active well within the current network. 1 Recommended Groundwater Monitoring Well Network and Sampling and Analysis Plan.City of Lathrop.
