Rhododendron Summer Homes Association
Consumer Confidence Report for the year 2004
Is my water safe?
Last year,
as in recent years past, your tap water met all U.S. Environmental Protection
Agency (EPA) and state drinking water health standards. Local
Water vigilantly safeguards its water supplies and once again we are proud to
report that our system has not violated a maximum contaminant level or any
other water quality standard. Except
During the year 2004 we did not test for Volatile organic compounds, when we
were notified of the error by the state, a test was conducted immediately to
provide compliance with the rules and results
confirmed the absence of the regulated containments. The reason why we missed this test is it was
required every three years and under the new rules it is now required every
year.
Do I need to take special precautions?
Some people may be more
vulnerable to contaminants in drinking water than the general population. Immuno-compromised 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. EPA/Centers 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 Water Drinking Hotline
(800-426-4791).
Where does my water come from?
The Rhododendron Summer Homes
obtains it source of water from Henry Creek with a diversion structure located
in Mount Hood National Forest in the foot hills of Zig Zag Mountain. The water is treated using Multimedia (sand)
filters and Rosedale brand cartridge filters to remove turbidity and
Giardia. Sodium Hypo chlorite is added
to provide a disinfection residual throughout the distribution system.
Source water assessment and its availability
A Source water assessment has
been completed by the Department of Environmental Quality of the State of
Oregon and the summary can be viewed at he following
web site

Why are there contaminants in my drinking water?
Drinking water, including
bottled water, may reasonably be expected to contain at least small amounts of
some contaminants. The presence of contaminants does
not necessarily indicate that water poses a health risk. More
information about contaminants and potential health effects can be obtained by
calling the Environmental Protection Agency's (EPA) Safe Drinking Water Hotline
(800-426-4791). The sources of drinking
water (both tap water and bottled water) include rivers, lakes, streams, ponds,
reservoirs, springs, and wells. As water
travels over the surface of the land or through the ground, it dissolves
naturally-occurring minerals and, in some cases, radioactive material, and can
pick up substances resulting from the presence of animals or from human
activity. Microbial contaminants, such
as viruses and bacteria, that may come from sewage
treatment plants, septic systems, agricultural livestock operations, and
wildlife. Inorganic contaminants, such
as salts and metals, which can be naturally-occurring or result from urban
stormwater runoff, industrial, or domestic wastewater discharges, oil and gas
production, mining, or farming. Pesticides and herbicides, which may come from a variety of sources
such as agriculture, urban stormwater runoff, and residential uses. Organic Chemical Contaminants, including
synthetic and volatile organic chemicals, which are by-products of industrial
processes and petroleum production, and can also come
from gas stations, urban stormwater runoff, and septic systems. Radioactive contaminants,
which can be naturally-occurring or be the result of oil and gas production and
mining activities. In order to
ensure that tap water is safe to drink, EPA prescribes regulations that limit
the amount of certain contaminants in water provided by public water
systems. Food and Drug Administration
(FDA) regulations establish limits for contaminants in bottled water which must
provide the same protection for public health.
How can I get involved?
Attend the Annual General
Meeting, It is held every year on a Saturday in May. You
can also help us keep costs down by reporting leaks and other maintenance
issues to Scott Weber at home 971-235-4615 or David Jacob at office
503-622-3911 cell 503-310-9262 home 503-622-6631
Other Information
Planned System Upgrades: The board this spring will review a variety
of projects including the installation of more valves and the replacement of
some piping for projects to be completed during the summer.
Water Quality Data Table
The table below lists all of the drinking water contaminants that
we detected during the calendar year of this report. The
presence of contaminants in the water does not necessarily indicate that the
water poses a health risk. Unless
otherwise noted, the data presented in this table is from testing done in the
calendar year of the report. The EPA or
the State requires us to monitor for certain contaminants less than once per
year because the concentrations of these contaminants do not change frequently.

ppm: parts per million, or milligrams per liter (mg/L) ppb: parts per billion, or micrograms per
liter (µg/L)
NTU: Nephelometric Turbidity Units. Turbidity
is a measure of the cloudiness of the water.
We monitor it because it is a good indicator of the effectiveness of our
filtration system.

Important Drinking Water
Definitions:
MCLG: Maximum Contaminant Level Goal: The level of a contaminant
in drinking water below which there is no known or expected
risk to health. MCLGs
allow for a margin of safety.
MCL: Maximum Contaminant Level: The highest level of a contaminant
that is allowed in drinking water. MCLs
are set as close to the
MCLGs as feasible using the
best available treatment technology.
TT: Treatment Technique: A required process intended to reduce the
level of a contaminant in drinking water.
AL: Action Level: The concentration of a contaminant which, if
exceeded, triggers treatment or other requirements which a water
system must follow.
MRDLG: Maximum residual disinfection level goal.
The level of a drinking water disinfectant below which there is no known
or
expected risk to health. MRDLGs do not reflect the benefits of the use of
disinfectants to control microbial contaminants.
MRDL: Maximum residual disinfectant level. There
is convincing evidence that addition of a disinfectant is necessary for control
of
microbial contaminants.
