Annual
Drinking Water Quality Report Riverdale City |
|
We
want you to understand the efforts we make to continually improve the
water treatment process and protect our water resources. We are committed
to ensuring the quality of your water. Our water source is Riverdale
Well #1, Riverdale Well #2 and the Weber Basin Water Conservancy District.
Our wells draw from the Delta Aquifer. We also purchase some of our
water from the Weber Basin Water Conservancy District Riverdale
City has a Drinking Water Source Protection Plan that is available for
review to our customers at our office. It provides more information
such as potential sources of contamination and our source protection
areas. I'm pleased to report that our drinking
water is safe and meets federal and state requirements. If
you have any questions about this report or concerning your water utility,
please contact Lynn Moulding at 394-5541 Ext. 219. 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 Tuesday of each month at 6:00 p.m. They are held at
the Riverdale Civic Center, 4600 S. Weber River Drive, Riverdale, Utah.
The dates, times and locations sometimes change, so please call for
current information. Water related issues are not always on the agenda,
please check the agenda in advance. Riverdale
City routinely monitors for constituents in our drinking water in accordance
with the Federal and Utah State laws. The following table shows the
results of our monitoring for the period of January 1st to
December 31st, 2001. All drinking water, including bottled
drinking water, may be reasonably expected to contain at least small
amounts of some constituents. It's
important to remember that the presence of these constituents does not
necessarily pose a health risk. In
the following table you will find many terms and abbreviations you might
not be familiar with. To help you better understand these terms we've
provided the following definitions: Non-Detects
(ND) - laboratory analysis indicates that the constituent
is not present. ND/Low
- High
- For water systems that have multiple sources of water, the
Utah Division of Drinking Water has given water systems the option of
listing the test results of the constituents in one table, instead of
multiple tables. To accomplish this, the lowest and highest values detected
in the multiple sources are recorded in the same space in the report
table. Parts
per million (ppm) or Milligrams per liter (mg/l)
- one part per million corresponds to one minute in two years or a single
penny in $10,000. Parts
per billion (ppb) or Micrograms per liter (ug/l)
- one part per billion corresponds to one minute in 2,000 years, or
a single penny in $10,000,000. Parts
per trillion (ppt) or Nanograms per liter (nanograms/l)
- one part per trillion corresponds to one minute in 2,000,000 years,
or a single penny in $10,000,000,000. Parts
per quadrillion (ppq) or Picograms per liter (picograms/l)
- one part per quadrillion corresponds to one minute in 2,000,000,000
years or one penny in $10,000,000,000,000. Picocuries
per liter (pCi/L) - picocuries per liter is a measure of
the radioactivity in water. Millirems
per year (mrem/yr) - measure of radiation absorbed by the
body. Million
Fibers per Liter (MFL) - million fibers per liter is a measure
of the presence of asbestos fibers that are longer than 10 micrometers. Nephelometric
Turbidity Unit (NTU) - nephelometric turbidity unit is a measure
of the clarity of water. Turbidity in excess of 5 NTU is just noticeable
to the average person. Action
Level (AL) - the concentration of a contaminant which, if
exceeded, triggers treatment or other requirements which a water system
must follow. Treatment
Technique (TT) - (mandatory language) A treatment technique
is a required process intended to reduce the level of a contaminant
in drinking water. Maximum
Contaminant Level (MCL) - (mandatory language) The “Maximum
Allowed” (MCL) is 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. Maximum
Contaminant Level Goal (MCLG) - (mandatory language)
The “Goal”(MCLG) is 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. Date-
Because of required sampling time frames i.e. yearly, 3 years, 4 years
and 6 years, sampling dates “May” seem out of date. Waivers
(W)- Because some chemicals are not used or stored
in areas around drinking water sources, some water systems have been
given waivers that exempt them from having to take certain chemical
samples, these waivers are also tied to Drinking Water Source Protection
Plans.
All
sources of drinking water are subject to potential contamination by
constituents that are naturally occurring or are man made. Those constituents can be microbes, organic
or inorganic chemicals, or radioactive materials. All 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 the water poses a health risk. More information about
contaminants and potential health effects can be obtained by calling
the Environmental Protection Agency’s Safe Drinking Water Hotline
at 1-800-426-4791. MCL’s
are set at very stringent levels. To understand the possible health
effects described for many regulated constituents, a person would have
to drink 2 liters of water every day at the MCL level for a lifetime
to have a one-in-a-million chance of having the described health effect. In
our continuing efforts to maintain a safe and dependable water supply
it may be necessary to make improvements in your water system. The costs
of these improvements may be reflected in the rate structure. Rate adjustments
may be necessary in order to address these improvements. Thank
you for allowing us to continue providing your family with clean, quality
water this year. In order to maintain a safe and dependable water supply
we sometimes need to make improvements that will benefit all of our
customers. These improvements are sometimes reflected as rate structure
adjustments. Thank you for understanding. 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/CDC guidelines on appropriate means to lessen the risk of infection
by cryptosporidium and other microbiological contaminants are available
from the Safe Drinking Water Hotline (800-426-4791).
We
at Riverdale City work around the clock to provide top quality water
to every tap. We ask that all our
customers help us protect our water sources, which are the heart of
our community, our way of life and our children’s future. Please
call our office if you have questions. Contact person: Lynn Moulding
