HomeMy WebLinkAboutDDW-2024-014107 he Directorate of Public Works and the Environmental Programs Division is pleased to present to you the 2020 Annual Drinking Water Quality Report for the English Village (EV) Water System. This report is designed to inform you about the quality of the water and the services we deliver to you on a daily basis. Our goal is to provide you with a safe and dependable supply of drinking water (DW). 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. All the water sources for EV are groundwater which we get from three wells, numbers 26, 27 and 30 outside of the EV residential area. But before we begin, let’s touch on a few issues so you can help us protect our DW. ource Protection Plan: The EPA and the State of Utah require us to develop and maintain a Source Protection Plan for each water system on the installation. The Source Protection Plan for Dugway – EV is on file at the Environmental Programs (EP) Office. It contains information about source protection zones, potential contamination sources, and management strategies to protect our DW. Our sources are located in remote, isolated areas and have very low potential for contamination. We have also developed management strategies to further protect our sources from contamination and have several trained personnel on source protection. Please contact the Water Quality (WQ) point of contact (POC), Steve Sheffey, at 435-881-6617 or at steven.s.sheffey.civ@mail.mil if you have questions about our source protection plans. ross connections and the water distribution system: 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 connections can adversely affect not only the availability but also the quality of your water. A cross connection may let polluted water or chemicals mingle into the water supply system when not properly protected. This not only compromises the water quality, but can also affect your health. Do not make or allow improper connections at your home. For example, 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 residence, it will affect you and your family first. If you desire more information about helping to protect the quality of our water, call the WQ POC, Steve Sheffey, at 435-881-6617 for more information on preventing cross connections at your residence. e are pleased to report that our DW meets Federal and State requirements. We want you to be informed about your DW. If you have any questions about this report or concerning your water, contact Steve Sheffey at 435-881-6617 or at steven.s.sheffey.civ@mail.mil. There are no regularly scheduled water quality meetings at Dugway; however, you are welcome to attend the Dugway town hall meetings when scheduled for updates. If an EP representative is not in attendance, submit your question to steven.s.sheffey.civ@mail.mil for review and feedback. Also, the Utah Division of Drinking Water (DDW) holds several board meetings during the year. If you are interested in attending a board meeting, go to https://deq.utah.gov/boards/utah-drinking-water-board- meetings for the schedule. T S C W 2 henega Facilities Management, as part of their base operations contract, routinely monitors for constituents in our DW in accordance with Federal, State and Army rules and regulations. The following table shows the results of the monitoring performed between January 1 and December 31, 2020, or the most recent sampling data. All DW, including bottled DW, may be reasonably expected to contain at least small amounts of some constituents. It is important to remember that the presence of these constituents does not necessarily pose a health risk. n the upcoming table, you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms please refer to the following definitions: or the “Level Detected” Column:  Low – High. For water systems with multiple sources of water, the Utah DDW offers the option of listing the test results of the constituents in one table. To accomplish this, the lowest and highest values detected in the multiple sources are recorded in the same space in the report table.  One part per million (ppm). One ppm corresponds to one minute in two years or a single penny in $10,000.  One part per billion (ppb). One ppb corresponds to one minute in 2,000 years, or a single penny in $10,000,000.  One part per trillion (ppt). One ppt corresponds to one minute in 2,000,000 years, or a single penny in $10,000,000,000.  Millirems per Year (mrem/yr). The measure of radiation absorbed by the body. On average, Americans receive a radiation dose of about 620 mrem/yr (source: www.nrc.gov).  Picocuries per liter (pCi/L). Picocuries per liter is a measure of the radioactivity in water.  Nephelometric Turbidity Unit (NTU). Nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTUs is just noticeable to the average person. or the Remaining Columns:  Maximum Contaminant Level Goal (MCLG). The “Goal” (MCLG) is the level of a contaminant in DW below which there is no known or expected risk to health. MCLGs allow for a margin of safety.  Maximum Contaminant Level (MCL). The “Maximum Allowed” (MCL) is the highest level of a contaminant that is allowed in DW. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. NOTE: MCLs are set at very stringent levels. To understand the possible health effects described for many regulated constituents, a person would have to drink two (2) liters, or a little over a half a gallon, 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. C I F F 3  Action Level (AL). The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.  Date. Because of required sampling time frames (i.e., yearly, 3 years, 4 years, 6 years, and 9 years), sampling dates may seem outdated, but all sampling is performed in accordance with state and federal requirements.  Violation Y/N. If it has an “N” and a smiley face ☺, it means there is no violation for that contaminant and the system is meeting the state and federal regulations.

We have learned through our monitoring and testing that some constituents have been detected at extremely low levels. The EPA and the State of Utah Division of Drinking Water have determined that your water IS SAFE at these levels. ll sources of DW 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 DW, 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 EPA Safe Drinking Water Hotline at 1-800-426- 4791 or on the EPA website at http://www.epa.gov. Note on Arsenic and Arsenic Treatment at DPG - EV: While your DW meets EPA's standard for arsenic, it does contain low levels of arsenic. EPA's standard balances the current understanding of arsenic's possible health effects against the costs of removing arsenic from DW. EPA continues to research the health effects of low levels of arsenic which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems. DPG built an arsenic treatment plant in EV and it went on-line in October 2006. The plant has been effectively removing most of the arsenic from your DW and keeping it under the EPA standard of 10 ppb. Samples are administered on-site by trained and certified operators every calendar quarter, as required by EPA and state regulations, and the samples tested at a state- certified laboratory to ensure proper arsenic treatment. pecial Notes on DW: Some people may be more vulnerable to contaminants in DW than the general population. Immune-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 DW from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by microbiological contaminants are available from the Safe Drinking Water Hotline at (800) 426-4791 or on the EPA website. f present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in DW is primarily from materials and components associated with service lines and home plumbing. 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 two 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 or inquire about past sample results. Information on lead in DW, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or specifically on the EPA website at http://www.epa.gov/safewater/lead. efore we close out this CCR, let’s talk about one more contaminant, PFAS. PFAS, or Per and Polyfluoroalkyl Substances, are a group of man-made chemicals used in a multitude of applications that encompasses several different chemicals. PFOA (Polyfluorooctanoic Acid) and PFOS (Perfluorooctanesulfonic Acid) are the two primary substances of concern currently, however, several states have regulated other PFAS compounds as well. Presently, Utah has not regulated any PFAS substances. The primary source of PFAS contamination for the Department of Defense has A A A S I B 5 come from Aqueous Fire Fighting Foam, or AFFF, applications and releases. Some of the concerns of PFAS include the following:  PFAS is highly persistent in the environment and bioaccumulates in the human body over a lifetime (i.e. “forever chemicals”).  PFOA/PFOS has been linked to reproductive and developmental disorders, liver and kidney diseases and has had immunological effects on the human body.  PFOA/PFOS have caused tumors in animal studies.  Data suggests that PFAS increases cholesterol levels, has effects on infant birth weights, affects immune systems, causes cancer, and thyroid hormone disruption. But there is GOOD NEWS for Dugway! The EP Office, in coordination with Chenega water operators and managers, and the Army Public Health Command has been sampling for PFAS contaminants in our groundwater sources, as well as our treated water since 2017, and NO PFAS HAS BEEN DETECTED IN ANY OF OUR SAMPLES! At present, PFAS is not a concern in our drinking water at Dugway Proving Ground ugway’s water operators, plumbers and compliance specialists work around the clock to provide top quality water to every tap. We are very conscientious about keeping our drinking water supply safe for consumption. We ask that all our residents help us protect our water sources, which are the heart of our community, our way of life and our children’s future. D
