ANNUAL WATER QUALITY REPORT
City of Dayton, Oregon
i
(For the Period January 1, 2003 through December 31, 2003~
The City of Dayton presents this
year's annual Water Quality
Report (WQR), also known as
the Consumer Confidence Report
(CCR). The United States
Congress, through the Safe
Drinking Water Act enacted 25
.* years ago, and amended in 1996,
requites drinking water systems
to give consumers this
information about their water systems each year.
This report was designed to provide you with
important information about the quality of the water
and services we deliver to you every day. Our constant
goal is to provide you with a safe and dependable
supply of drinking water. We also want you to
understand the efforts we make to continually
improve the water treatment process and protect our
water resources. We work closely with various
regulatory agencies to assure this water quality.
We're pleased to report that our drinking water is
ude and meets federal and state requirements. If
you have any questions regarding this report, please
contact Sue Holiis, City Admlms" tmttr, at (503)864-
2221. We went our valued customers to be informed
about their water utility.
Where Do We Get Our
Drinking Water?
Our water supply comes
from wells and sprin
About 80*/, of our water is
produced by 5 wells - 2 st
the basa of the Red Hills of
Dundee and 3 ~de the city
limits. The other 20 ,6 of our
wa~ comes from 12 springs
located in the Red Hills of Dundee approximately 2
miles northeast of Dayton, These sources can produce
about 380,000 gallons of water per day. We use an
average of 250,000 gallons per day in winter and
425,000 gallons a day in summer. We also have 2
additional wells that have been drilled and will begin
to be used in July 2004.
How Do We Protect Our
Drinking Water?
Federal and state regulations include procedures and
schedules for monitoring water from the source,
within the distribution system, and at the tap. The
Oregon Health Division (OHD) ensures that public
water systems comply with all regulations, follow
monitoring schedules, and report monitoring results.
To ensure that tap water is safe to drink, the
Environmental Protection Agency (EPA) prescribes
limits on 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.
All drinking water, including bottled water, contains
at least small amounts of some contaminants. The
presence of contaminants does not necessarily
indicated that the water poses a health risk 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 radioactive
material, and can pick up substances resulting from
the presence of animals or from human activity.
The City of Dayton routinely monitors for various
contaminants in the drinking water. The tests for these
substances are established by various Federal and
State laws. Some of the required tests are performed
twice a month, annually or every 3 to 5 years. In all,
we test our water for 106 different contaminants. All
testing is performed by independent certified
laboratories. We are proud to announce that we have
had no violations during the period of this report.

part of the
The City of Dayton also
complies with safe drinking
water regulations by
disinfecting drinking water
with chlorine. In additior~
some well water is filtered as
treatment process.
Another important element of good water quality is
the effective management of the water distribution
system The City has approximately 8-9 miles of
distribution piping and three reservoirs that store
almost a million gallons of water. It is important for
water to remain fresh, so storage time in the reservoirs
is limited. Each month, we analyze water samples at
two locations within the distribution system for
microbial content. One of these locations changes
each month so that each sector of the city (north,
south, east and west), is tested at least every 4 months.
We protect our water sources by limiting access to the
area or buildings, using fencing and locks. We also
follow up on customers' water quality concerns.
Our staffstrives to provide top quality water to ever7
customer. We ask that all our customers help us to
conserve and protect our water sources which are the
heart of our community, our way of life, and our
children's future.
C. Pesticides and herbicides, which may come
from a variety of sources such as agriculture, storm
water runoff, and residential use.
D. Organic chemical contaminants, including
synthetic and volatile organics, which are by-products
of industrial processes and petroleum production, and
can also come from gas stations, urban storm water
runoff, and septic systems.
E. Radioactive contaminants, which can be
naturally occurring or be the result of oil and gas
production and mining activities.

On Friday, June 13, 2003, a routine water sample tested positive for fecal coliform or e. coli bacteria. Residents
were immediately notified to boil all drinking water. This type of bauteriai contamination can occur when run-off
enters the drinking water supply, because of a break in the distribution system, a failure in the water treatment
process, or a contaminated sample collection bottle. Upon notification, the City immediately checked all chlorine
stations to assure proper operation and increased the level ofcklorine as a precaution, Flyers were passed out door-
to-door and staff worked with the print, radio and television media to get additional notice and information out
to system users. Repeat testing of the sample station and points on either side of it were done immediately. The
results of these tests showed no fecal coliform or E. col] contamination. The boil drinking water warning was lifted
On July 15, 2003, after the results of the follow-up testing showed no positive samples.
DON'T FORGET THESE TIPS ON SAVING WATER (AND MONEY!)
Check every faucet ~ toilet for leaks. Even
a slow drip wastes a lot of water in a day.
Keep a jug of drinking water in the
refrigerator, then you won't have to let the
water run to cool it.
Turn off the water while
you are brushing your
teeth or washing your
hands or when scraping
the dishes.
Install water-saving
shower heads or flow
restrictors
Landscape your yard with drought-resistant
trees and plants or those native to Oregon.
~ Check your local library, garden center, or the
' Native Plant Society for ideas.
Don't forget to keep your pet's water bowl full
and place it in a shady location. From time to
time, add ice cubes to cool and freshen the

lawn.
Be careful to water the lawn, not the sidewalk

day (10:00 am - 6:00 pm). As much as 50o,4 of
the water can be lost to evaporation.
Do not usa a bose to clean off the driveway,
sidewalks or patio. A broom is better. It saves
water and keeps oil, grease and :ngine coolant
f~om contaminating our waterways.

UPDATE
ON WATER SYSTEM IMPROVEMENT PROJECT
f
The contract to replace certain in-town distribution piping and transmission piping
from the new wells to the treatment facility is virtually complete. The treatment
facility and reservoir site Is approximately 90% complete. TestJng of pumps and
treatment equipment is underway. Barring any unforseen problems with equipment
or treatment protocols, water from the new system should begin flowing In eady to
mid-3uty.
Watch for announcements In the local newspaper or your water/sewer bills for the
actual start up date. Tours of the facility will also be offered at that time.
