Arvin Community Services District Has Levels of Arsenic
Above Drinking Water Standards
Water produced by Wells of the Arvin Community Services District recently failed a drinking water
standard. Although this is not an emergency, as our customers, you have a right to know what you should
do, what happened and what we are doing to correct this situation.
We routinely monitor for the presence of drinking water contaminants. Testing results collected on April
5, 2016 show that our system exceeds the standard, or maximum contaminant level (MCL), for Arsenic.
The standard for Arsenic is 10 ug/L. The range of results for the 2nd quarter, 2016 was 15-29.
What should I do?
•
•
•
You do not need to use an alternative (e.g., bottled) water supply. However, if you have
specific health concerns, consult your doctor.
This is not an emergency. If it had been, you would have been notified immediately. However,
some people who drink water containing arsenic in excess of the MCL over many years may
experience skin damage or circulatory system problems, and may have an increased risk of
getting cancer.
If you have other health issues concerning the consumption of this water, you may wish to
consult your doctor.
What happened? What was done?
The Federal Government lowered the arsenic MCL from 50 ugiL effective on Jan.23, 2006. Arvin
Community Services District's Board of Directors has been very active in seeking a solution to removing
Arsenic from Arvin's public water supply to meet the new lower standard. The District has been applying
for Government grants and has been approved for a grant from the State Water Resources Control Board,
Division of Drinking Water to construct new wells or install treatment equipment to remove the Arsenic
from the public water supply. New well sites are being looked for where tests show arsenic levels within
the new standard.

QUESTIONS
If you have any questions about this report or concerning your water utility, please contact Raul
Barraza with Arvin Community Services District at 661-854-2127. We want our valued customers to be
informed about their water utility. If you want to learn more, please attend any of our regularly
scheduled meetings. They are held on the first and third Monday of each month at 6:00 P.M., at the
District office at 309 Campus Drive, Arvin, California. We encourage public interest and
participation in our community's decisions affecting drinking water and any other issues.
Arvin Community Services District routinely monitors for contaminants in your drinking water
according to Federal and State laws. This table shows the results of our monitoring for the period of
January 1st to December 31st 2015. For those regulated contaminates the system is allowed to monitor
for less often than once a year, the most recent testing done in accordance with the regulations has been
used. We are required to monitor your drinking water for specific contaminants on a regular basis. Results
of regular monitoring are an indicator of whether or not our drinking water meets health standards.
How to Read This Table
In order to ensure that tap water is safe to drink, the U.S. Environmental Protection Agency (USEPA) and the State
Water Resources Control Board, Division of Drinking Water (Division) prescribe regulations that limit the amount of
certain contaminants in water provided by public water systems. Division regulations also establish limits for
contaminants in bottled water that provide the same protection for public hetlth.
The results of tests performed in 2015 or the most recent testing ava\able are presented in the table. In addition to
the constituents listed in the report, we have conducted monitoring on all active wells for additional organic chemicals for
which the State Water Resources Control Board, Division of Drinking Water (Division) and USEPA have not yet set a
standard, and all results were below detection levels unless otherwise noted. For additional water quality data, contact Raul
Barraza at 661-854-2127. Terms used in the Water Quality Table and in other parts of this report are defined here.
Maximum Contaminant Level or MCL: The highest level of a contaminant tJIat is allowed in drinking water. Primary
MCLs are set as close to the PHGs (or MCLGs) as is economically and tecbnologifally feasible. Secondary MCLs are set to
protect the odor, taste, and appearance of drinking water.
Maximum Contaminant Level Goal or MCLG: The level of a contaminant in drinking water below which there is no
known or expected risk to health. MCLGs are set by the U.S. Environmental Protection Agency.
Public Health Goal or PHG: The level of a contaminant in drinking water below which there is no known expected risk
to health. PHGs are set by the California Environmental Protection Agency.
Primary Drinking Water Standard or PDWS: MCLs for contaminants that affect health along with their monitoring and
reporting requirements, and water treatment requirements.
Secondary Drinking Water Standard or SDWS: MCLs for contaminants that affect taste, odor; or appearance of the
drinking water. Contaminants with SDWSs do not affect the health at the MCL levels.
Range: The lowest to the highest values for all samples tested for each contaminant. If only one sample is tested, or no
range is required for this report, then no range is listed for that contaminant in the table.

Arsenic
•
Some people who drink water containing arsenic in excess of the MCL over many years could experience skin
damage or problems with their circulatory system, and may have an increased risk of getting cancer. The
Federal government lowered the arsenic MCL from 50ug/L to 10ug/L effective on Jan. 23, 2006. Arvin
Community Services District's Board of Directors has been very active in seeking a solution to removing arsenic
from Arvin's public water supply to meet the new lower water standard. The District has been researching
solutions to meet the new arsenic standard. The District has been applying for government grants and has been
approved for a grant from the State Water Resources Control Board to construct 2 new replacement wells in
2016 and also looking to obtain funds for 3 more replacement wells.

Additional General Information on Drinking Water
•
All Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of
contaminants, not necessarily indicate that water poses a health risk. More information about contaminants and
potential health effects can be obtained by calling the USEPA's Safe Drinking Water Hotline (1-800-426-4791).
The sources of drinking water (both tap water and bottled water) in~ude rivers, lakes, streams, ponds, reservoirs,
springs, and wells. As water travels over the surface of the land Jt. through the ground, it dissolves naturallyoccurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the
presence of animals or from human activity.
•
Contaminants that may be present in source water include:
_(A)
Microbial contaminants, such as viruses and bacteria that may come from sewage treatment plants,
septic systems, agricultural livestock operations, and wildlife.
...
(B)
Inorganic contaminants, such as salts and metals, that can be 11aturally-occurring or result from urban
storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
(C)
Pesticides and herbicides, that may come from a variety of sources such as agriculture, urban storm
water runoff, and residential uses.
(D)
Organic chemical contaminants, including synthetic and volatile organic chemicals that are by-products
of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff,
agricultural application, and septic systems.
(E)
Radioactive contaminants that can be naturally-occurring or be the result of oil and gas production and
mining activities.
•
Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone
organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be
particularly at risk from infections. These people should seek advice about drinking water from their health care
providers. USEPNCenters for Disease Control (CDC) guidelines on appropriate means to lessen the risk of
infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water
Hotline (1-800-426-4791).
•
The average nitrate level was 13.83 ppm with a maximum level of 42 ppm. Nitrate in drinking water at levels
above 45 ppm is a health risk for infants of less than six months of age. Such nitrate levels in drinking water can
interfere with the capacity of the infant's blood to carry oxygen, resulting in serious illness; symptoms include
shortness of breath and blueness of the skin. Nitrate levels above 45 ppm may also affect the ability of the blood
to carry oxygen in other individuals, such as pregnant women and those with specific enzyme deficiencies. If
you are caring for an infant, or you are pregnant, you should ask advice from your health care provider.
•
If present, elevated levels of lead can cause serious health problems, especially for pregnant woman and young
children. Lead in drinking water is a primary from materials and components associated with service lines and
home plumbing. Arvin Community Services District is responsible for providing the highest possible quality
drinking water, but cannot control the variety of materials used in plumbing components. When your water has
been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30
seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water,
you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you
can take to rmmrruze exposure is available from the Safe Drinking Water Hotline or at
http://www.epa.gov/safewater/lead.

While the District was meeting the EPA standard for arsenic of 50 ppb prior to the change of the standard in January 2006, the District does not meet the new
standard of 10 ppb that was adopted in January 2006. Some people who drink water containing arsenic in excess of the MCL over many years could
experience skin damage or problems with their circulatory system, and may have an increased risk of getting cancer.
2.
1,2,3-trichloropropane (1,2,3 TCP) has been detected at levels in excess of the PHG (0.7 ppt). Some people who drink water containing 1,2,3 TCP in excess of the
Public Health Goal over many years may have an increased risk of getting cancer, based on studies in laboratory animals. The District is concerned about the TCP
levels, and is investigating treatment options. An MCL is being developed for TCP.
