1 DRINK LOCAL TAP WATER! 2017 ANNUAL WATER QUALITY CONSUMER CONFIDENCE REPORT PARK CITY Dear Park City Water Cutomer, working hard to deign and contruct a complete, redundant water We are pleaed to provide the 2017 Drinking Water Quality treatment ytem that will provide afe, plentiful drinking water for Conumer Confidence Report. Once again, Park City Water ha generation to come. Lat year, we completed two capital project WATER QUALITY provided the highet-quality drinking water and cutomer ervice for our reident, viitor and buinee. with year pat, all to help hore up the entire ytem and meet increaingly tringent federal and tate regulation: we ignificantly upgraded the Quinn drinking water met or exceeded quality tandard et by the Junction Water Treatment Plant (which treat water from the Weber Environmental Protection Agency and Utah Diviion of Drinking Water for all River) and contructed a new treatment facility next to Creekide Park. You can teting from January through December read more about both project elewhere in thi report. Setting the Standard for Excellence Future pital Project Park City ha one of the mot complex municipal water ytem in the country. In addition to thee project, we are deigning the 3King Water Treatment Plant Although we are claified a a mall water ytem, by the U.S. Environmental to treat Judge and Spiro Tunnel.

2 CREEKSIDE WATER TREATMENT PLANT The building wa deigned with the neighborhood in mind We are happy to announce the completion of the Creekide Water Treatment Plant, which it adjacent to Creekide Park on Hoay Ranch Loop Road. Thi newly oed plant treat water from two well: Divide Well and Park Meadow well. In 2006 (and again in 2012), the Park Meadow well wa deignated a being under the influence of urface water, which triggered more tringent regulation to protect public health and afety. The new facility treat the water with ultraviolet light, chlorine, and cartridge filtration. On-ite chlorine generation Chlorine-feed pump On-ite Chlorine Generation The plant wa deigned firt and foremot with the afety of the urrounding neighborhood in mind: the chlorine ued in the treatment proce i actually generated on-ite, rather than being trucked in. The only chemical delivered to the location i alt, a key component in chlorine. When electricity i applied to a water-alt mixture, chlorine i produced. In addition, the chlorine generated through thi proce i very low-trength (0.8 percent), a oppoed to what had been hipped in (12 percent). Thi offer a much afer and more environmentally friendly alternative. Energy-efficient Deign We are alo proud of the new building advanced energy-efficiency feature, including enhanced building envelope ytem to reduce heating and cooling demand, heat recovery ytem, and photovoltaic (olar) panel that provide enough power to meet the building lighting and heating need. Park City ha the mot ambitiou climate goal in North America (we are on track to achieve net-zero municipal carbon emiion by 2022), and our water-treatment facilitie are a key part of our energy-reduction trategie. SURFACE WATER TREATMENT The Quinn Junction Water Treatment Plant i a tate-of-the-art facility that treat water from the Weber River uptream of Rockport Reervoir with microfiltration, organic contaminant removal, tate and odor control, ma removal, and chlorine diinfection. THREE WELL SOURCES Middle School Well Creekide Water Treatment Plant Divide Well Park Meadow Well Treated by cartridge filtration and ultraviolet light due to claification by Utah DDW a a groundwater under the influence of urface water. ONE SPRING Thiriot Spring ONE TUNNEL SOURCE Spiro Tunnel treated through a coagulation/filtration plant for reduction of arenic and thallium to meet the MCL and reduction of iron and ma to below the aethetic econdary MCL. Treated Spiro Water i blended with Thiriot Spring under a Utah DDW-approved plan to reduce antny concentration. WHOLESALE TREATED WATER Jordanelle Special Service Ditrict SOURCE PROTECON PLAN Park City Drinking Water Source Protection Plan wa initially approved by the tate in 1999 and wa updated in 2011 and It contain information about ource-protection zone, potential contamination ource and management-protection trategie. Potential contamination ource common in our protection area are reidential propertie; roadway; infratructure (i.e., ewer and torm drain); golf coure; mine tailing and related mine working; and ki-reort operation.

HELP MAINTAIN YOUR DRINKING WATER PLUMBING Park City Water Department i dedicated to delivering high-quality drinking water, and it i important homeowner and buinee undertand their reponibility beyond the meter. the meter, each cutomer i reponible for the quality of their water. The American Water Work ociation ha developed video and brochure with tip on maintaining high-quality water in home and buine, a well a information about home treatment ytem. For detail, pleae viit DrinkTap.org and click Water Info. Certain time of the year Park City home and buinee ue very little water, epecially hot water. It i important to conduct proper maintenance prior to bringing building plumbing back into ervice (e.g., fluhing boiler/hot water heater, unued faucet, etc.).

4 QUINNS JUNCON WATER TREATMENT PLANT Recent upgrade will help enure reliability while contributing to the City energy-efficiency goal The Quinn Junction Water Treatment Plant began operating in 2011 to treat a new ource for the City: water from the Weber River uptream of Rockport (the firt urfacewater ource in the City portfolio). In heavy runoff year, however, the plant had to be hut down for two-to-three month becaue it could not proce large volume of poor quality water during warm-winter torm or pring runoff. Lat year, the plant underwent a erie of upgrade to addre four iue: Quinn Junction WTP microfilter Year-round pacity: The City increaed the plant overall capacity to treat organic contaminant in the water year-round (becaue the Weber River i urface water, the primary contaminant are organic from farm or thoe naturally occurring in oil) with an additional granular activated carbon (GAC) veel. The plant can now operate even day a week, 365 day a year, at a rate of 4.2 million gallon per day. Filter: The City intalled new filter veel to remove ma, a heavy metal that occur naturally in oil throughout the United State. doe not have an MCL (the primary health tandard), but turn the water a yellowih-brownih color when it come into contact with chlorine. Fan reduce tratification of air Backwah Bain: A large bain wa added behind the building to backwah the large filter veel (backwahing clean filter media by ending water backward through the veel). South-facing olar wall Energy Upgrade: The City intalled a very large fan in the proce area to reduce tratification of air (puh the hot air down). Thi increae the effectivene of the heating and cooling ytem, greatly reducing cot. The City alo intalled a outh-facing olar wall, which ue paive olar heating to upplement the building heating need. (The facility need to maintain a very conitent temperature for the variou treatment procee.) Smaller finihed water pump were alo intalled to provide more efficient pumping during low-water demand time period. IMPORTANT DEFINIONS & ABBREVIAONS ACON LEVEL (AL): The concentration of a contaminant which, if exceeded, trigger treatment or other requirement that a water ytem mut follow. LOCAONAL RUNNING ANNUAL AVERAGE (LRAA): Sample collected for four conecutive quarter at one ample location, with reult averaged over that period. MAXIMUM CONTAMINANT LEVEL GOAL (MCLG): The level of a contaminant in drinking water below which there i no known or expected rik to health. MCLG allow for a margin of afety. MAXIMUM CONTAMINANT LEVEL (MCL): The highet level of a contaminant allowed in drinking water. MCL are et a cloe to the MCLG a poible, uing optimal treatment technology. MAXIMUM RESIDUAL DISINFECTANT LEVEL GOAL (MRDLG): The level of a drinking water diinfectant below which there i no known or expected rik to health. MRDLG do not reflect the benefit of the ue of diinfectant to control microbial contaminant. MAXIMUM RESIDUAL DISINFECTANT LEVEL (MRDL): The highet level of a diinfectant allowed in drinking water. There i convincing evidence that addition of a diinfectant i neceary for control of microbial contaminant. NOT APPLICABLE (NA): The meaurement doe not apply. NON-DETECT (ND): No contaminant level detected during teting. NEPHELOMETRIC TURBIDITY UNITS (NTU): Meaure of water clarity. PICOCURIES PER LITER (PCI/L): Meaure of the radioactivity in water. PARTS PER BILLION (PPB) OR MICROGRAMS PER LITER (MG/L): Unit decribe the level of detected ubtance. One ppb i approximately equal to one drop of water in a mall backyard wimming pool (13,000 gallon). PARTS PER MILLION (PPM) OR MILLIGRAMS PER LITER (MG/L): Unit decribe the level of detected ubtance. One ppm i approximately equal to one drop of food coloring in 13 gallon of water. SECONDARY MAXIMUM CONTAMINANT LEVEL (SMCL): USEPA doe not enforce SMCL. They are etablihed only a guideline to ait public water ytem in managing their drinking water for aethetic conideration, uch a tate, color and odor. Thee contaminant are not conidered to preent a rik to human health at the SMCL. TREATMENT TECHNIQUE (TT): A required proce intended to reduce the level of a contaminant in drinking water. VARIANCE: Permiion not to meet an MCL under certain condition. WAIVERS: Becaue ome chemical are not ued or tored in area around drinking water ource, ome water ytem have been given waiver that exempt them from having to take certain chemical ample, thee waiver are alo tied to Drinking Water Source Protection Plan.

5 Quinn Junction WTP ma filter Creekide WTP filter EPA HEALTH INFORMAON To enure your tap water i afe to drink, the Environmental Protection Agency precribe limit on the amount of certain contaminant in water provided by public water ytem. The Food and Drug Adminitration regulation etablih limit for contaminant in bottled water, which mut provide the ame protection for public health. Drinking water, including bottled water, may reaonably be expected to contain at leat mall amount of ome contaminant. The preence of contaminant doe not necearily indicate that the water poe a health rik. For more information about contaminant and potential health effect, call the EPA Safe Drinking Water Hotline, The ource of drinking water (tap and bottled) include river, lake, tream, pond, pring and well. water travel over the urface of the land or through the ground, naturally occurring mineral and radioactive material are diolved. The water can alo pick up ubtance reulting from the preence of animal or human activity. Contaminant that may be preent in ource water include: (A) Microbial contaminant, uch a virue and bacteria, which may come from ewage treatment plant, eptic ytem, agricultural livetock operation and wildlife. (B) Inorganic contaminant, uch a alt and metal, which can be naturally occurring or reult from urban torm water runoff, indutrial or dometic watewater dicharge, oil and ga production, mining, or farming. (C) Peticide and herbicide, which may come from a variety of ource uch a agriculture, torm water runoff and reidential ue. (D) Organic chemical contaminant, including ynthetic and volatile organic, which are byproduct of indutrial procee and petroleum production; can alo come from ga tation, urban torm water runoff and eptic ytem. Quinn Junction WTP (E) Radioactive contaminant, which can be naturally occurring or the reult of oil and ga production and mining activitie. ATTENON IMMUNOCOMPROMISED PERSONS Some people may be more uceptible to contaminant in drinking water than the general population. Immunocompromied peron undergoing chemotherapy, peron who have undergone organ tranplant, people with HIV/AIDS or other immune ytem diorder, elderly people and infant can be particularly at rik for infection. If applicable, pleae eek advice from your healthcare provider. EPA/ CDC guideline on appropriate mean to leen the rik of infection by Cryptoporidium and other microbial contaminant are available at the Safe Drinking Water Hotline, ABOUT LEAD Preent, elevated level of lead can caue eriou health problem, epecially for pregnant women and young children. in drinking water i primarily from material and component aociated with ervice line and home plumbing. The Park City Water Department i reponible for providing highquality drinking water but cannot control the variety of material ued in plumbing component. When your water ha been itting water quality teting for everal hour, you can minimize the potential for lead expoure by fluhing your tap for 30 econdto-two minute before uing water for drinking or cooking. If you are concerned about lead in your water, you might want to have it teted. Information on lead in drinking water, teting method and tep you can take to minimize expoure i available from the afe Drinking Water Hotline or at epa.gov. Depite concern about drinking water, the EPA note that the greatet expoure to lead i wallowing or breathing in lead paint chip or dut.
