RECOMMENDATION: That the Board of Public Utilities approve a Professional Services Agreement with Geoscience Support Services, Inc., of La Verne, California, in a not-to-exceed amount of $317,851 for geohydrologic professional consulting services for a well rehabilitation and groundwater monitoring program. BACKGROUND: Riverside's domestic and irrigation water supplies come from a large network of wells that produce water from the local groundwater basins. The reliability and sustainability of this water supply is dependent upon the health of the groundwater basins and the efficiency of the wells and pumping plants. For this purpose, Riverside has developed a well rehabilitation program and has taken measures to monitor and control the groundwater basins. However, additional expertise is needed. The science behind production well efficiency is site specific and complex. With an average age of 57 years (oldest is 113 years) and a replacement cost of $1.5 million, these wells need to be maintained and operated as efficiently as possible. As for monitoring wells, many of them are old production wells that may be poorly located and sized to monitor groundwater quality and quantity. For these reasons, the services of a hydrogeologist are necessary to review the well rehabilitation and monitoring well programs. A Request for Proposals (RFP) was sent to 17 consultants with well rehabilitation and groundwater monitoring expertise. From the proposals received, five consultants were selected for interviews. Geoscience was determined to be the best qualified firm to provide the services. The negotiated scope and price are included in the agreement. Work will include, among other things, assisting staff with developing a prioritized list for well rehabilitation, developing a well rehabilitation specification. reviewing the monitoring well program and identifying ideal locations for new monitoring wells.
