HomeMy WebLinkAboutDDW-2024-009638Quality Annual Drinking Water Report Vivian Park Homeowners 2023 The following report is designed to inform you about the quality of the water and services delivered to you every day. The goal is to provide you with a safe and dependable supply of drinking water and to help you understand the efforts made to continually improve the water treatment process and protect your water sources. The Drinking Water Source Protection Plan for Vivian Park Homeowners contains information about source protection zones, potential contamination sources, and management strategies to protect your drinking water. The sources have been determined to have a low susceptibility to potential contamination. There are many connections to the water distribution system. When connections are properly installed and maintained, the concerns are very minimal. However, unapproved and improper connections can adversely affect the quality of the water. A cross-connection may allow polluted water or even chemicals to mingle into the water supply system when not properly protected. This not only affects the water quality but may also affect your health. A cross-connection is any connection or structural arrangement of pipe between a public water system and anything else, through which backflow can occur. An example of backflow potential is when a vacuum is formed in a water system when the water is shut off for repairs, or during peak usage such as fighting a fire. Even attached hoses left in standing water are potentially a source of backflow. When this occurs it is possible for contaminated water to be drawn back into the drinking water system. The elimination of this problem is the intent behind installing backflow prevention devices on each of your hose bibs. - The sources of drinking water for our system include Vivian Park Well and Vivian Park Spring. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. - Contaminants that may be present in source water include: 1. Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. 2. Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming. 3. Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, and residential uses. 4. Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems. 5. Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities. 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 (800) 426-4791. In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health. Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer and oundergoing 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 microbial contaminants are available from the Safe Drinking Water Hotline (800) 426-4791. If 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. We 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. CONSTITUENT TABLE DEFINITIONS 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 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. Date - Because of required sampling time frames i.e. yearly, 3 years, 4 years and 6 years, sampling dates may seem out-dated. 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. Source Water Information Source Water Name Type of Water Source ID Vivian Park Well GW WS001 Vivian Park Spring GW WS002 UTAH25006 Provo City GW WS003 During the months May through October of 2023 the state required samples of the spring water independent of the well water and before it is chlorinated in the tank. These samples were collected from a hose extending from the box on top of the tank. By turning a valve, water from the spring can be diverted through the hose before it enters the tank. Samples from this source were coliform positive in each of the months reported. This was not unexpected as water from most springs will be the same. Under normal circumstances this water enters the tank where it is chlorinated and from there it travels through the distribution system free of any coliform.

Coli 2023 1 (April) No goals None Y Human and animal fecal waste Sanitary Survey On July 28, 2021 Chris Martin of the Division of Drinking Water at the State visited Vivian Park for the purpose of completing a “Sanitary Survey” which is done regularly every 3-5 years. A Sanitary Survey is basically an audit of the community’s water system. It includes safety protocols, assures for proper licensing of operators, documentation of procedures, and a review of the “Source Protection Plan.” This plan is typically performed by an engineering firm which looks at a variety of aspects associated with the area around a well or spring. One of the required components of the Source Protection Plan is that the area surrounding a spring be fenced. Given the location of the Vivian Park spring it was determined by State officials that fencing would be problematic at best. Lacking a fence around the source, Vivian Park is obligated to provide other assurances of source protection to assure contamination of the water does not occur. These assurances began with the testing of the spring water monthly from May through October. Because of the positive tests for coliform in these monthly samples, an MPA test was required and daily chlorination testing is also required beginning in May of 2022. The results of the MPA test were included in a letter received July 26, 2022 which stated: “An MPA sample was collected from Vivian Park Spring (WS002) on June 7, 2022. The sample scored 1, indicating low risk.” Routine Testing The following samples were taken in July of 2022 and submitted to ChemTec-Ford laboratory for testing. All sample results were sent to the State. These tests are on a three year rotation so these samples will not need to be submitted again until 2025. A table of the sample results follow: Lead and Copper Year Sampled Highest Sample Result EPA MCL Units Violations Likely Source of Contamination Cu 2022 .263 1.3 mg/L N Erosion of natural deposits; leeching from wood preservatives; corrosion of household plumbing systems Pb 2022 .0026 0.015 mg/L N DBPs Year Sampled Sample Result EPA MCL Units Violations Likely Source of Contamination HAAs 2022 ND 60 total ug/L N Disinfection byproducts THMs 2022 ND 80 total ug/L N Disinfection byproducts Regulated Contaminants Contaminants Year Sampled Sample Result Min Report Limit MCL Units Violation Likely Source of Contamination Discharge from metal refineries; Erosion of natural deposits.

Having just described the fencing issue and its ramifications, I think it is important to mention that at the end of the Sanitary Survey performed by Chis Martin, Vivian Park was assessed 0 points (demerits) for violations. This is a first in my experience! Recommendations for a previous Sanitary Survey done in 2018 are listed below. The only item on the current list is the well head displacement and the supplemental testing to be done with the spring. Vivian Park added a generator to power the well if a power outage occurs. This insures a continuous water supply to the community in emergencies without having to negotiate with Provo City for help. This said, it is my feeling that if Vivian Park ever was in a situation that required help from Provo City, negotiations would not be difficult. Updates: The Avalanche During the last week of March 2023, an avalanche occurred at the water tank covering about 80% of the surface of the tank and destroying the chlorination shed located on top of the tank. We weren’t able to expose the chlorination shed until around July and at that time did significant repairs to the shed and had to replace the chlorination controls inside. We were finally able to bring the chlorination system back on line around the first of August. During this time, water was provided to the community via the well. Water was tested at the well regularly during these months and was without any contaminants. Butonce the water entered the tank it picked up coliform and then entered the distribution system positive for coliform. A boil order was issued during this time and there was no incidence of sickness as a result of the water. In the future, we plan to add a dual tank system that will chlorinate at the well and use the system at the tank as a back up. Site Protection Plan A Site Protection Plan was completed by Infinity Consultants after it was determined that a fence surrounding the spring was not necessary for an acceptable result. In the past, we were told that a fence needed to inclose the spring area in order for the site protection plan to be accepted. With that in mind, we decided there was no point in doing the source protection plan if there was no chance of it being accepted without the fence. Since this time, we have been told that keeping a Source Protection Plan up to date is still a requirement. An temporary exception for the fencing was granted but to continue the exception we were required to complete an MPA test. This test would determine if there was surface water present in the ground water of the spring. In June, 2022 Chris Martin (State Division of Drinking Water) brought equipment to complete the MPA testing. The water from the spring was filtered under pressure for an extended period of time and then the filter was examined under a microscope to determine if there were contaminants in the water. The sample scored a 1which indicates a low risk for MP contamination. We will have to submit a request to extend the exception for the “fencing violation” by September of 2023, but with these results, hopefully, the State will be willing to extend the exception. Updates on Recommended Improvements Sanitary Survey: Conducted November 1, 2018 by Ryan Dearing (State of Utah Water Resources). The following actions need to be addressed to bring system into compliance: Send information on Cross-connections that are included in the by-laws. (Submitted 2019) Emergency Response Plan Well: air vents need to be raised and then downturned a. along path leading to the well (completed 2018) b. from the well-house leading outside (completed 2018) Fill in hole in the casing (cable runs into it) (completed 2018) Do a threadless tap on the sampling line (completed 2018) The air-in valve should be opened and screened. (completed 2018) Gasket to lid of tank needs to be replaced. (completed 2018) 8. Elevation of well casing is inadequate. Needs to be 12” above well house floor. (To be completed by 2024) Springbox needs a new gasket and overflow drain. (Completed Fall, 2019) 10. Tool kit Respirator Level at which chlorine can be determined. How is level of tank maintained? Float? Binder that includes: Authority statement (Refers to CCC – Submitted August, 2019) CCR - year to year (Up-to-date) Log of incidents (a description of any cross-connection infractions and how they were dealt with) Site Protection Plan A Site Protection Plan was completed by Infinity Consultants after it was determined that a fence surrounding the spring was not necessary for an acceptable result. In the past, we were told that a fence needed to inclose the spring area in order for the site protection plan to be accepted. With that in mind, we decided there was no point in doing the source protection plan if there was no chance of it being accepted without the fence. The reasoning for the previous stance is seen in the paragraph below. Requested an exception for a fence surrounding the spring area (2018). The exception was denied but would be considered if an MPA test was completed. This test would determine if there was surface water present in the ground water of the spring. The board decided not to have this test done by the state because if it was determined that surface water was present it would require a lot of updating to the spring which could prove basically impossible. Failure to make these changes would also force a closure of the spring. We will receive deficiency points for not building the fence but it would not necessarily force closure of the spring. Previous Sanitary Survey Recommendations: Include a statement in the by-laws regarding a cross-connection control plan. Should include a statement of consequences for not abiding cross-connection rules as stated in the by-laws. Completed 2016 An inventory of hose bib vacuum breakers: where they are located , the type of vacuum breaker, etc. Ongoing, but a good amount of this inventory was completed in the Fall of 2019 with the help of Vivian Park residents. A note from the fire department saying that in the event of fire, water can be used from the pond or river. By code, there must be 120,00 gallons of water available in the event of fire. The tanks has a 42,000 gallon capacity, so additional water resources must be available. (Letter was requested from Scott Hart, North Fork Fire Department, May, 2019) (Requested again June 2020) (Completed Summer 2020) Exemption letter for the following: TD09 Improper location for ventilating fan suction in the chlorine house TD10 Air inlets not located near ceiling w/louvre (exemption requested) TD13 Feed vent improperly vented or screened (correction completed) The chlorination house will have to be reconstructed as the avalanche destroyed the original structure. These recommendations will be implemented in the construction of the new house.

Recertification completed 2018 & 2021. A cross-connection certification is now required as well. Certification completed December, 2019. Must be updated yearly through CEUs. (Update completed November 2022.) The completion of these updates in 2020 allowed the state to classify our system with an “approved” rating. The only outstanding requirement by the state is the raising of the well head, but they have given us until 2024 for this to be completed. It may also be possible to lower the floor rather than raise the head to meet compliance for this requirement. Certified operator ( Certification completed – Matt Clark – Completed November, 2015.
