HomeMy WebLinkAboutDDW-2024-014106Annual Drinking Water Quality Report 2020Vernon Waterworks Special Service District We're pleased to present 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 source have been determined to be fromgroundwatersources. Our water source isPumped Well.The Drinking Water Source Protection Plan for Vernon Waterworks SSD is available for your
review. It contains information about source protection zones, potential contamination sources and management strategies to protect our drinking water. Our sources have been determined
to have a low level of susceptibility from 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 protected. This 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 across connection. When the cross connectionis 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.This report shows our water quality and what it means to you our customer. If you have any
questions about this report or concerning your water utility, please contact Darrell Holden at 435-839-3464. 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 1st Wednesday at 7:00 pm at the Fire Station.Vernon Waterworks SSDroutinely 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, 2020.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) - A treatment technique is a required
process intended to reduce the level of a contaminant in drinking water.Maximum Contaminant Level (MCL) - 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) - 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.Maximum Residual Disinfectant Level (MRDL) - The highest
level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.Maximum Residual Disinfectant
Level Goal (MRDLG) - 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. Date- Because of required sampling time frames i.e. yearly, 3 years, 4 years and 6 years, sampling dates may seem outdated.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.

Water additive used to
control microbesIf present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials
and components associated with service lines and home plumbing.Vernon Waterworks SSDis responsible for providing high 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 minimize exposure is available from the safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.All sources of drinking water are subject to potential
contamination by constituents that are naturally occurring or manmade. 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.MCLs 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.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 from their health care providers about drinking water.
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 atVernon Waterworks SSDwork 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.
