Long Beach Regional-Scale Well Siting Study
Over half of the City of Long Beach’s water supply is produced from groundwater wells which deliver water to the Long Beach Groundwater Treatment Plant (GWTP). LBWD’s goal is to optimize local water supply sources and maintain well field capacity through well rehabilitation and installation of new wells. This requires locating a number of suitable well sites, an assessment of the hydrogeologic and engineering feasibility of those wells sites, and an evaluation of how the wells can be incorporated into LBWD’s collection system.
City of Hemet Exploratory Drilling Program
The feasibility of a potential well site location within the City of Hemet was assessed through drilling of an exploratory borehole and installation of a nested monitoring well to evaluate depth-specific water quality. The area is subject to many groundwater quality issues from thermal upwelling of groundwater through the area’s many faults, and impacts from agricultural activity within the valley.
Suburban Water Systems Well Rehabilitation
Suburban Water Systems Plant 409 was in need of rehabilitation due to declining production. Kyle Groundwater conducted a well assessment and developed program of mechanical and chemical cleaning to restore production. The project was successfully completed on schedule and within budget despite significant project pressures that required close coordination with the well owner, multiple contractors, and regulators.
Puente Basin Water Authority Well Siting Study
The Puente Basin Water Agency (PBWA) is seeking to develop a source of potable groundwater supply in the Whittier area of the Central Basin. A Well Siting Study was conducted Spring 2018 to evaluate areas favorable for installation of new production wells within the Central Basin, and within relative proximity to existing pipelines. Potential sites were identified within areas that did not fall within zones of exclusion and ranked based upon a scientific approach and weighted decision matrix.
City of Riverside Public Utilities Consulting
Kyle Groundwater provides as-needed hydrogeological consulting to the City of Riverside Public Utilities, a large municipal public water agency. Recent projects include well condition assessments for two production wells, for which tailored diagnostics, as well as rehabilitation and redevelopment programs were recommended. Kyle Groundwater has also provided peer review during siting and design of a new high-capacity municipal water supply well.
Indio Water Authority Well Rehabilitations
The Indio Water Authority (IWA) requested Kyle Groundwater to conduct a thorough assessment of two wells that had sat idle for more than a year. Each well was assessed and a work plan developed for mechanical and chemical cleaning, and redevelopment through airlifting and swab, and pump and surge. The first well has been successfully rehabilitated and is back in service, and the second well is currently undergoing redevelopment.
