Sonoma County Water Fluoridation Analysis of Impacts on Fish


Sonoma County Water Fluoridation
Analysis of Impacts on Endangered Fish

The Sonoma County Board of Supervisors is currently studying the fluoridation of the water provided by the Sonoma County Water Agency, which provides drinking water to the majority of county residents.  A Fluoridation Advisory Committee (FAC) was appointed to provide recommendations to the Department of Health Services, based on a preliminary engineering design and cost estimate, public input and financial planning.  A working group of the FAC seeks a technical analysis to review the possible effects, if any, of community water fluoridation on the Endangered Species Act specified fish population.


The Sonoma County Department of Health Services, Administrative Division, is requesting qualifications from proposers to provide an Aquatic Assessment and Mass Balance Calculation of public water fluoridation currently under consideration.

Evaluation of all statements of qualifications relative to this RFQ must be received by 2:00 p.m. on January 17, 2014 at 3313 Chanate Road, Santa Rosa, CA 95401, attention Kim Caldewey.  The County will enter into a professional services agreement with the most qualified individual(s)/firm(s) to provide the services described in this RFQ. Please see attached County of Sonoma sample agreement, including insurance exhibit.

It is the policy of the County of Sonoma to promote local employment and business opportunities. A local service provider has a valid physical address located within Sonoma County where they perform business on a day-to-day basis and holds a valid business license if required. Extra percentage weighing of 5% shall be provided in the total rating score for local service providers.  If hiring sub-contractors, the County strongly encourages using local service providers.

References and client lists provided by you may be contacted by Division staff during the evaluation process.


Provide a literature review, interpretation and technical report on what existing scientific data and the specific characteristics of the discharge systems in Sonoma County suggest in relation to the potential impact of water fluoridation to 0.7 – 0.9 mg/L on water quality and ESA listed species (NCC Steelhead, CC Coho; Salmon and CC Chinook Salmon) within the proposed action area. The report should include: 

1.  Use a Mass Balance approach to determine expected fluoride concentrations and major inputs of fluoridated potable water in the Sonoma County Water Agency service area. The calculation will include an analysis of the geographic boundaries, water transport pathways in Sonoma County and major inputs of potable water from wastewater discharge and irrigation runoff of recycled water to the Sonoma County Water Agency service area.

2.  A review and analysis of scientific literature on the known effect of various concentrations of fluoride, at various Ph levels and temperatures, and considering the duration of exposure, on the ESA listed salmonids.

Report authors will present their findings to public bodies and government officials and be available to answer technical questions and provide clarification upon request.


1.   Provide a description of the firm qualifications, experience and expertise to provide the services described in the scope of work.

2.   Provide at least three references to previous projects that are of similar size and scope.

Reference information should include description of the project, name of owner, address, telephone number and person to contact if we so choose.

3.   Provide an itemized budget clearly stating all costs associated with completion of the scope of work.

4.   Disclose any debarment or other disqualification as a vendor for any federal, state or local

entities. Proposer must describe the nature of the debarment/disqualification, including where and how to find such detailed information.

5.   Provide project organization and staffing.

6.   Provide a brief description of the firm’s proposed approach to the project.
