A Solid Track Record in Groundwater Basin Management

For nearly four decades, GEOSCIENCE has partnered with Southern California’s leading water districts to provide groundwater basin management. We have successfully conducted groundwater basin assessments and computer modeling of the majority of the groundwater basins in Southern California.

GEOSCIENCE staff understands that the keys to the success of such basin-wide programs require a thorough knowledge of basin geohydrology; an understanding of the issues and concerns of the basin management environment; the collection and review of accurate and comprehensive data, the use of state-of-the-art GIS for data analysis and display; and appropriate and adequately calibrated models. We have decades of experience assisting clients and have faced the challenges related to meeting water supply needs in an environmentally responsible and sustainable manner.

Many GEOSCIENCE projects have focused on the groundwater modeling and water budget studies that are a critical first step in determining the safe or perennial yield necessary to maintain basin sustainability. Our experience in devising and implementing plans in more than 70 such projects—often with multiple stakeholders and pursuing diverse objectives and strategies, take into account such issues as:

  • Geohydrological assessments, investigations and analyses
  • Groundwater flow and solute transport models
  • Artificial recharge
  • Conjunctive use
  • Groundwater basin management programs
  • Water quality
  • Salt and Nutrient Management Plans
  • Aquifer storage and recovery (ASR) programs
  • DWSAP programs

The tools available to water purveyors, from district-wide groundwater basin management programs and Salt and Nutrient Management Plans to the newly enacted Sustainable Groundwater Management Act of 2014, are among a portfolio of planning-based approaches to carefully manage groundwater resources. Whether the objective is to replenish groundwater supplies, reduce dependence on imported water supplies, improve local storage options, promote drought protection, or mitigate land subsidence, the experienced staff at GEOSCIENCE can help you meet the challenge.

In recognition of its efforts in groundwater management, GEOSCIENCE was the recipient of:

  • ASCE Award, 2010, Outstanding Project of the Year, Beaumont Cherry Valley Water District Recharge and Recreation Facility
  • California Water Association, 2004, Mountain & Desert Region Research Achievement Award, Pilot Scale Artificial Recharge Testing – Big Bear Area Regional Wastewater Agency, Recycled Water Artificial Recharge and Recovery Study
