At the Coachella Valley Water District, Water Quality staff
members make it their top priority to ensure that your
drinking water meets all federal and state water quality standards.
Th ese highly trained employees collect and test drinking water,
review the latest scientifi c studies on water contaminants and
monitor government action to change drinking water standards.
Th e Coachella Valley Water District is governed by a locally
elected board of directors, who normally meet in public session at
9 a.m. on the second and fourth Tuesdays of each month at the
district’s Coachella offi ce at Avenue 52 & Highway 111.
Th is annual report documents the extremely high quality of
water served to all Coachella Valley Water District’s water users.
All domestic water served by the Coachella Valley Water
District is obtained locally from wells drilled into the Coachella
Valley’s vast groundwater basin.
Most water quality testing is performed in the district’s state-
certifi ed laboratory. A few highly specialized tests are performed
by other laboratories.
In addition to the detected constituents listed in the table on the
following pages, CVWD’s water quality staff monitors for more
than 100 other regulated and unregulated chemicals. All of these
are below detection levels in CVWD’s domestic water.
While all of CVWD’s domestic water supply meets current
requirements, drinking water supplied to some service areas does
contain low levels of arsenic. Th e standard for arsenic balances the
current understanding of the chemical’s possible health eff ects
against the costs of removing this naturally occuring element from
drinking water. Th e California Department of Health Services
continues to research the health eff ects of low levels of arsenic,
which is a mineral known to cause cancer in humans at high
concentrations, and is linked to other health eff ects such as skin
damage and circulatory problems.
With respect to the presence of arsenic in drinking water in
excess of 10 ug/L but less
