Clawson Town2024 - Annual Drinking Water Quality Report
By Castle Valley Special Service District
Castle Valley Special Service District presents to you this year's Annual Drinking Water
Quality Report. This report is designed to inform you 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 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 sources are surface water taken from Millsite Reservoir and treated at CVSSD’s Ferron Water Treatment Plant.
The Drinking Water Source Protection Plans for CVSSD’s Ferron Water Treatment Plant are
available for your review. They contain information about source protection zones, potential
contamination sources and management strategies to protect our drinking water. Potential
contamination sources common in our protection areas are coal mining, truck traffic on the highways, and recreational activities. Our sources have a low susceptibility to potential
contamination. We have also developed management strategies to further protect our
sources from contamination. Please contact us if you have questions or concerns about our
source protection plan.
There are many connections to our water distribution system. When connections are properly installed and maintained, the concerns are very minimal. However, unapproved
and improper piping changes or connections can adversely affect not only the availability,
but also the quality of the water. A cross connection may let polluted water or even
chemicals mingle into the water supply system when not properly connected. The most
likely possibility for a cross connection is the secondary irrigation system. It is against the
law to make any connection between the culinary and secondary system. DO
NOT DO IT!! A cross connection not only compromises the water quality but can also affect your health. So, what can you do? Do not make or allow improper connections at
your homes. Even that unprotected garden hose lying in the puddle next to the driveway is
a cross connection. The unprotected lawn sprinkler system after you have fertilized or
sprayed is also a cross connection. When the cross connection is allowed to exist at your
home it will affect you and your family first. If you’d like to learn more about helping to
protect the quality of our water, call us for further information about ways you can help.
Your drinking water meets federal and state drinking water quality
requirements. If you have any questions about this report or concerning your water utility,
please contact Jacob Sharp at 381-5333. 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 3rd Thursday of each month at 7:00 p.m. at the
CVSSD office located at 20 South 100 East, Castle Dale, Utah.
Castle Valley Special Service District, acting for Clawson Town routinely monitors for
contaminants 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, 2024.
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 EPAs Safe Drinking Water Hotline at [phone].
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.
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.
Maximum Contaminant Level (MCL) - The “Maximum Allowed” (MCL) is the 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) - 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, 6 years, and
9 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.
