The East Bay Municipal Utility District (District) is conducting a water quality improvement project for San Pablo Reservoir, in El Sobrante, California.  The District is planning to determine the best options for reducing geosmin, MIB, and soluble manganese to reduce taste and odor issues. Stillwater Sciences is leading a team of consultants contracted to assist the District in this project. 

Stillwater led a Screening Workshop and an Alternatives Evaluation Workshop with District staff to identify feasible control measures for San Pablo Reservoir that would deliver the best benefit for the money spent.  We also prepared an Alternatives Evaluation Report, which identifies the preferred alternative solution(s) to reduce geosmin, MIB, and manganese levels.

The Stillwater Team developed the preliminary design for the preferred alternative, including installation and operation. This has included pre-design coordination meetings and a field visit, which culminated in a preliminary design workshop and report.  The Stillwater Team also developed a water quality monitoring plan for the reservoir, including implementation, effectiveness, and validation monitoring elements.
