Preliminary report on the groundwater isotope study in the Brentwood Region

PDF Version Also Available for Download.

Description

Under contract with the City of Brentwood and auxiliary support by the East Contra Costa Irrigation District (ECCID), a preliminary research assessment of the groundwater resources beneath the Brentwood region is complete. The research was performed by an isotope geochemistry approach rather than traditional hydrogeological methods. The isotope approach is inexpensive relative to the traditional methods and has been used here mostly as a tracer that details the source, migration paths, and migration rates of existing groundwater supplies. In addition, the isotope results provide a quantitative framework in which to answer questions important to Brentwood including: (1) What is the ... continued below

Description

Under contract with the City of Brentwood and auxiliary support by the East Contra Costa Irrigation District (ECCID), a preliminary research assessment of the groundwater resources beneath the Brentwood region is complete. The research was performed by an isotope geochemistry approach rather than traditional hydrogeological methods. The isotope approach is inexpensive relative to the traditional methods and has been used here mostly as a tracer that details the source, migration paths, and migration rates of existing groundwater supplies. In addition, the isotope results provide a quantitative framework in which to answer questions important to Brentwood including: (1) What is the long-term and short-term sustainability of the groundwater resources relative to current urban growth projections? (2) How can the good water quality be maximized in groundwater wells under short and long-term groundwater use schemes? (3) What underground areas exist within the Brentwood region that indicate untapped groundwater supplies that may provide plentiful, good quality water? This preliminary report focuses only on the first question. The second and third questions will be addressed in the final report to be completed by January 1, 1995. Furthermore, the conclusions in this preliminary report of how much groundwater is available for use will be incorporated into the Groundwater Management Plan currently being developed by the ECCID in conjunction with the City of Brentwood.
