Team Edwards,
Congratulations to Dominic Cook, winner of the Branch Elementary first and sec- Illustration Provided by Dominic Cook (2nd Grade), Branch

a spirit of water conservation and an understanding of why water is important for
life. The picture is published as part of the 2014 Edwards AFB Main Base and Air
Force Research Laboratory Detachment 7 Consumer Confidence Reports.
Edwards Bioenvironmental Engineering is pleased to share on behalf of Brig.
Gen. Carl E. Schaefer, 412th Test Wing commander, that EAFB provides healthy
drinking water. The CCR communicates this assessment to water recipients regard-
ing the previous year’s water quality. The CCR outlines Environmental Protection
Agency and California Department of Public Health contaminant maximum levels,
and goals respectively as well as compares local results to EPA and CDPH values.
The CCR also includes information on source water and educational information.
Along with being a mandatory requirement, the CCR is an opportunity to communi-
cate the value of water, to promote wise use, to build community trust and customer
satisfaction, and to encourage investment in resource protection and infrastructure.
The CCR is published with guidance from the State of California’s CCR Guid-
ance Manual. California requires more information and, in some cases, different
information than the federal rules. EAFB is mandated to follow state regulations
and it guidance manual; much of the language found in the 2014 EAFB Main Base
and AFRL CCR cannot be edited.
The CCR will also be available at a later date at www.edwards.af.mil.
Contact 661-277-3272 for questions. Edwards AFB Bioenvironmental Engineer-
ing will be happy to assist you.

The EAFB Main Base Drinking Water System draws water from two sources:
TERMS USED IN THIS REPORT
1. On-base ground water wells.
2. Surface water supplied by the Antelope Valley East Kern Water Agency. ppm: parts per million or milligrams per liter (mg/L)

These wells are fed by the Antelope Valley Aquifer. The water from these wells travels to a
