Safe Drinking Water
Drought State of Emergency
With California facing water shortfalls in the driest year in recorded state history,
Governor Edmund G. Brown Jr. proclaimed a State of Emergency on January 17, 2014
and directed state officials to take all necessary actions to prepare for these
drought conditions. DEHS is compiling a resource list for both water system operators
and the public to help save water and respond appropriately. This resource list
can be found on our
Environmental Health Emergencies
Drinking Water Systems
The Division of Environmental Health Services (DEHS) Small Drinking Water System
Program protects public health and safety by inspecting water systems to ensure
pure and safe drinking water is supplied throughout San Bernardino County. In partnership
with small drinking water systems owners/operators in our County, DEHS conducts
routine inspections to prevent waterborne diseases, identify risks of bacteriological,
chemical and/or radiological contamination, and provide technical assistance. DEHS
has an agreement with the California Department of Public Health, Drinking Water
Program (State Water Board) for administration and enforcement of the Federal and
State statutes and regulations for any water systems under 200 service connections.
Currently, there are 272 small drinking water systems.

DEHS is utilizing a grant to take domestic well water samples for known or suspected constituents of
concern for our Domestic Well Water Sample Program (DWWS). Our goal is to identify constituents of
concern and to notify the property owner of the results so they may properly informed regarding their
well water. Should you have questions regarding sample results please visit www.epa.gov/drink

Cross Contamination and Backflow Prevention
The County of San Bernardino requires that domestic water systems within this jurisdiction are protected
against contamination or pollution as a result of inadequate protection due to the lack of or malfunctioning
of backflow prevention assemblies. In addition, State regulated water purveyors are also required to monitor
backflow prevention devices to meet the California Code of Regulations, Title 17 requirements.
A Certificate of Competence issued by DEHS is required to inspect, maintain, or test water back flow prevention
assemblies. All new registrants must successfully pass a written exam before sitting for the practical exam.
All certificate holders who wish to renew must demonstrate competence at the practical exam. Candidates who are
successful will receive a certificate. DEHS offers the option of being placed on our commercial testers list
that is published below and solicited by water purveyors. DEHS currently offers four testing dates per year;
typically in March, June, September and December.
For more information on the backflow program or to find out about upcoming backflow
certification test dates, please contact DEHS at 1-800-442-2283.
