- The campus Registered Environmental Health Specialist
(REHS) serves as a resource person for the campus community for current
information on drinking water issues.
- To provide reasonable and adequate guidance to
the campus community in addressing issues related to the campus drinking
EH&S is designated as the official campus office
for contact or coordination with all agencies having interests or jurisdiction
affecting UC Irvine in the field of drinking water quality. EH&S works
with the Irvine Ranch
Water District and the State Health Department in the protection of
the campus drinking water supplies.
Irvine Ranch Water District-(IRWD): The water
utility that supplies drinking water to the campus community.
Primary Drinking Water Standards: Contaminants
in drinking water that adversely affect human health.
REHS: Registered Environmental Health Specialist
(i.e. Health Inspector).
Secondary Drinking Water Standards: Constituents
in drinking water that may adversely affect the taste, odor or appearance
of the water.
Service Connection: The water meter where
the IRWD water main connects to the customer’s plumbing system.
State Health Department- (DHS): For the purpose
of this program, refer to the California State Department of Health Services
Division of Drinking Water and Environmental Management.
4.1 The Department of Health Services is responsible
for the enforcement of the Federal and California Safe Drinking Water
Acts (SDWAs) and the regulatory oversight of approximately 8,700 public
water systems to assure the delivery of safe drinking water to all Californians.
This includes the Irvine Ranch Water District.
4.2 The Irvine Ranch Water District is responsible
for monitoring the campus water supply and ensuring that the water delivered
to the campus community meets the standards required by the DHS.
4.3 Environmental Health and Safety:
4.3.1 Serves as the campus liaison between the
Department of Health Services, the Irvine Ranch Water District and
the campus community.
4.3.2 Oversees the installation of all new water
distribution lines on campus property-see Section 5.01 - Disinfection
Procedure for Water Distribution Lines
Specific Program Components
Sources of Supply:
IRWD tap water is a blend of surface water imported by the Metropolitan
Water District (MWD) and local well water pumped from the Dyer Road
Wellfield in Santa Ana.
MWD surface water sources include rivers, lakes, streams, ponds, reservoirs
or springs located in the Colorado River Basin and the California
State Water Project in Northern California.
Drinking Water Quality:
California State Drinking Water Act prescribes regulations that limit
the amount of certain contaminants in water. IRWD's Water Quality staff
conducts over a quarter of a million laboratory tests each year from
water taken from over 70 sample points throughout the District.
Primary Drinking Water Standards:
Water Quality staff continuously monitors the campus water supply,
conducting over 100 bacteriological tests each week from water
taken from sample points located near the campus service connections.
supports the IRWD sampling program by conducting bacteriological
tests on water taken from the distribution systems of all new
construction on campus.
Inorganic and Organic Chemicals and Radiological Contamination:
sources of these contaminants include agricultural runoff, erosion
of natural deposits and industrial pollution. Some of these
contaminants include arsenic, nitrates, organic solvents and
monitors for these contaminants on a yearly basis except for
Nitrates/Nitrites. Nitrate/Nitrite monitoring is performed on
a quarterly basis.
Secondary Drinking Water Standards:
contaminants are regulated to maintain the aesthetic qualities of
the water. Their presence in tap water does not pose a health hazard.
contaminants include color, odor or turbidity of the water and other
organic and inorganic chemicals not listed as primary contaminants.
Unregulated Organic Chemicals
of these contaminants include organic chemicals used as agricultural
pesticides and other industrial solvents.
- IRWD monitors for these contaminants every five years.
Records of all bacteriological analyses are kept for 5 years.
Records of all chemical analyses are kept for 10 years.
Records of all water quality and system water outage complaints are
kept for 5 years.
These records are available for review by IRWD customers upon request.
IRWD provides the DHS a monthly summary of all sampling activities performed
in the previous month.
IRWD provides an annual water quality report to its customers. The latest
IRWD annual water quality report is available for review at:
2014 Water Quality report
IRWD notifies its customers, in writing, when the IRWD water supply fails
to meet the provisions of the California Safe Drinking Water Act. The
notification letter outlines the nature and extent of the violation(s)
and what steps the IRWD has taken to correct the violation(s).
