What We’ve Done

These are some of our most notable projects, that span our experience in Reliable Groundwater Production, Sustainable Groundwater Management and Modeling, Augment Groundwater Supply and Groundwater Rights Defense.

  • All
  • Augment Groundwater Supply
  • Defend Groundwater Rights
  • Reliable Groundwater Production
  • Sustainable Groundwater Management and Modeling

Olivenhain Municipal Water District, Groundwater Supply and Brine Management Program

Olivenhain Municipal Water District (OMWD) serves approximately 84,000 customers in the communities of Encinitas, Carlsbad, portions of San Diego, San Marcos, and Solana Beach. Because OMWD relies almost entirely on imported water from the California and Colorado aqueducts, the district is investigating ways to develop local water supplies.

City of Oceanside, Multiple Projects

Geoscience has completed multiple projects for the City including groundwater recharge feasibility studies, design, and grant application support.

Yucaipa Valley Water District, Oak Valley Town Center Recharge Project

The Oak Valley Town Center is a planned, large-scale, mixed use development that initially planned to spread recycled water using decorative lakes. However, our investigations found that recharge via spreading basins was not feasible and that artificial recharge using injection wells was best suited to the site geology.

Doheny Ocean Desalination Project

Municipal Water District of Orange County (MWDOC) has conducted detailed investigations to determine the feasibility of providing an ocean water desalination supply source in south Orange County utilizing slant well technology.

Elsinore Valley Municipal Water District, Well Rehabilitation

The Elsinore Valley Municipal Water District (EVMWD) was founded in 1950 and provides water service to the city of Lake Elsinore and surrounding communities. Currently, the district serves more than 45,000 water, wastewater, and agricultural connections. GEOSCIENCE recently provided recommendations and oversaw well rehabilitation for five existing wells, and is currently rehabilitating three wells for the district.

Western Municipal Water District, Riverside- Arlington Basin Groundwater Sustainability Plan

Western Municipal Water District was formed in 1954 to bring supplemental water (the Colorado River and State Water Project) to western Riverside County, and serves more than 23,000 retail water customers and 130 irrigation customers. To meet demand, the District also uses supplemental groundwater from the Arlington Subbasin.

City of Pismo Beach, Regional Groundwater Sustainability Project (RGSP)

The Regional Groundwater Sustainability Project (RGSP) is a regional recycled water project that will reduce the risk of seawater intrusion and improve sustainability for the region’s water supply.

Paso Robles Basin Study

The Paso Robles Groundwater Basin (Basin) encompasses a 790‐square mile area in the upper Salinas River watershed in Central California. During the last 15 years, the area has experienced both growth in population as well as an increase in water use from a burgeoning wine industry.

Rancho California Water District Groundwater Management Program

The Rancho California Water District (RCWD) overlies a groundwater basin encompassing approximately 90 square miles of area in Riverside County of Southern California. Approximately half of the annual water needed by the District is produced from saturated alluvial deposits through a system of 100 deep wells.

San Bernardino Valley Municipal Water District, Upper Santa Ana River Integrated Model

The Santa Ana River (SAR) watershed is the largest in Southern California and home to some of the fastest population growth in the country. The communities in the upper watershed from the Seven Oaks Dam upstream, to the Prado Dam downstream, rely on groundwater for much of their water supply.

Monterey Bay Desalination Project

To alleviate environmental stresses on the Carmel River, the State Water Resources Control Board required California American Water Company (Cal Am), the utility responsible for providing water to a substantial portion of the Monterey Peninsula, to reduce its reliance on diversions from the Carmel River to serve as its local water supply.

Libya vs. Brasoil

The Antelope Valley groundwater adjudication is the largest groundwater rights dispute in California. The 16-year-old class action involved competing water rights claims by multiple parties and stakeholders—from individual property owners, agricultural interests, public water suppliers and the United States government.

Bellflower-Somerset Mutual Water Company, Leahy Avenue Well

The Leahy Avenue Well project’s preliminary design phase was completed in 2013, however, due to permitting issues, the project was delayed for five years. GEOSCIENCE worked with Bellflower-Somerset Mutual Water Company to modify the schedule and budget to get the project back on track and completed. We successfully resolved permitting issues and oversaw efforts to demolish an existing well onsite that was taken off-line because of high arsenic levels.
