&EPA Oasis A/lobile Home Park Drinking Water Update

U.S. Environmental Protection Agency

San Francisco,

March 2 02 3

What Happened?

Recent drinking water samples at Oasis
Mobile Home Park's (Oasis MHP)
water system found arsenic level above
the federal Safe Drinking Water Act's
(SDWA) maximum contaminant level
(MCL) of 10 parts per billion (ppb). The
water system is not properly operated
and is contributing to elevated levels of
arsenic in the water being delivered to
residents of the park. On September
14, 2021, EPA issued a new
Emergency Administrative Order. The
order requires Oasis MHP to provide
alternate water to residents at no
additional cost while it fixes its water
system.

What's Arsenic?

Arsenic is a naturally-occuring
element found across the United
States. Consuming water with levels of
arsenic that exceed the Safe Drinking
Water Act standard, over many years,
may cause skin damage, circulatory
system problems and/or an increased
risk of cancer. (See the websites at
the end of this fact sheet for more
information on arsenic.)

What if my water
looks different?

For any water emergencies,
including changes in color and
odor, call Oasis emergency
line 24/7 at: (909) 372 - 8438
EPA does not have the ability
to enforce taste, color and
odor standards.

What's Next?

Oasis MHP must continue to assess and mitigate its operational issues, continue to monitor
its water system and provide regular updates to EPA to make sure it meets all the terms and
conditions of the Emergency Administrative Order and Safe Drinking Water Act.

Is Oasis MHP Water Safe to Use?

EPA recommends residents use bottled water for drinking and cooking. EPA will notify
residents when bottled water is no longer needed.

Residents should
use bottled water
for drinking,
cooking, and
brushing
teeth.

Residents may use tap
water for bathing,
showering, and
washing vegetables
but should not
ingest the
water during
these activities.

Each resident is entitled to receive
one gall on of water daily at no
cost. Water can be picked up at the
