10 20 2 2 Annual Drinking Water Quality Report Johnston County Public Utilities Water system number East 40 - 51 - 018 Water system numbe r West 03 - 51 - 070 ___________________________________________________________________________________________________________________________________________ We are pleased to present to you this year’s Annual Drinking Water Quality Report This report is a snapshot of last year’s water quality Included are details about from where your water comes , what it contains , and how it compares to standards set by regulatory agencies 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 and to providing you with this information Éste informe contiene información muy importante sobre la calidad de su agua potable Una copia de este reporte en español está disponible en la Oficina de Servicio Público en el Centro de Land Use The Johnston County water system has two service areas called Johnston East and Johnston West The Johnston East service area is generally described as the area east of the Neuse River and south of I - 95 The Johnston West service area is the area west of the Neuse River and north of I - 95 Please refer to the map Water supplied to Johnston East has free chlorine as a secondary disinfectant Water supplied to Johnston West has chloramines a combination of chlorine and ammonia as a secondary disinfectant The quality data for both service areas are provided to all customers We provide service for communities , towns and cities throughout our county including most unincorporated parts of the county and the towns of Archer Lodge , Four Oaks , Princeton , Kenly , Clayton , and Wilson’s Mills The County system also supplements the towns of Micro , Benson , Pine Level , Smithfield , Selma , and Fuquay Varina with additional water When You Turn on Your Tap , Consider the Source In 2022 , our water department produced and provided approximately 30 billion gallons of water to our customers Our water source is surface water from the Neuse River , which forms just above Durham where the Eno and Flat Rivers converge The Neuse River flows approximately 190 miles through eastern North Carolina to the Pamlico Sound The Johnston County intake and treatment facility are located one half mile east of Wilson’s Mills , NC There are two reservoirs on site Each reservoir contains 35 million gallons The treatment system has five main steps to remove or reduce harmful contaminants presedimentation , coagulation , clarification , filtration by multimedia high rate filters , and disinfection Once treatment is complete , water is pumped into elevated storage tanks for distribution throughout the water system Johnston County also purchases water from the Town of Smithfield , Harnett County , City of Raleigh , City of Wilson , Sampson County , Northwest Wayne Sanitary District and Southwest Wayne Sanitary District on a bulk basis The source of the Smithfield and City of Raleigh supply is the Neuse River and the Harnett County supply is the Cape Fear River The City of Wilson utilizes Buckhorn Reservoir as their water supply source , while Sampson County and the Wayne Sanitary Districts have ground water supply wells Their treatment processes are similar to the County’s and water purchased from bulk suppliers mixes with water produced by the County in the distribution system Annual report s for the County’s bulk water suppliers can be viewed on each of their websites Please see last page of report for links to all purchased water systems water quality reports The US Environmental Protection Agency EPA wants you to Know 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 Environmental Protection Agencys EPA Safe Drinking Water Hotline 800 - 426 - 4791 The sources of drinking water both tap water and bottled water include rivers , lakes , streams , ponds , reservoirs , springs , and wells 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 microbial contaminants , such as viruses and bacteria that may come from sewage treatment plants , septic systems , agricultural livestock operations , and wildlife ; 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 ; pesticides and herbicides , which may come from a variety of sources such as agriculture , urban storm water runoff , and residential uses ; 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 ; and radioactive contaminants , which can be naturally occurring or be the result of oil and gas production and mining activities 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 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 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 Water Drinking 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 Johnston County Public Utilities is 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 wwwepagov safewater lead In 2021 , EPA finalized a major update to rules regarding lead and copper in drinking water The update , known as the Lead and Copper Rule Revision LCRR , provides an improved level of public health protection The revisions focus on providing increased levels of protection from lead exposure in drinking water to children at schools and childcare facilities , identifying and removing lead service lines , and providing information about lead in drinking water to the community Johnston County has consistently maintained compliance with all water quality requirements , including full compliance with the original Lead and Copper Rule Over the next several months , we will be completing a study to verify compliance with the LCRR This will include developing an inventory of all water service line materials in our community , developing a plan to sample for lead at our schools and childcare centers , and developing a program to educate our customers about lead inPagedrinking water Additional information the LCRR can be found at drinking water Additional information the LCRR can be found at drinking water Additional information the LCRR can be found at Source Water Assessment Program SWAP Results The North Carolina Department of Environment and Natural Resources DENR , Public Water Supply PWS Section , Source Water Assessment Program SWAP conducted assessments for all drinking water sources across North Carolina The purpose of the assessments was to determine the susceptibility of each drinking water source well or surface water intake to Potential Contaminant Sources PCSs The results of the assessments are available in SWAP Assessment Reports that include maps , background information and a relative susceptibility rating of Higher , Moderate or Lower The relative susceptibility rating of the source for Johnston County Public Utilities was determined by combining the contaminant rating number and location of PCSs within watershed and the inherent vulnerability rating ie , characteristics or existing conditions of the watershed and its delineated assessment area It is important to understand that a susceptibility rating of “ higher ” does not imply poor water quality , only the systems ’ potential to become contaminated by PCS’s in the assessment area The assessment findings are summarized in the table below Susceptibility of Sources t o Potential Contaminant Sources PCSs Source Name Susceptibility Rating SWAP Report Date Neuse River Higher September 2020 The complete SWAP Assessment report for Johnston County Public Utilities may be viewed on the Web at https wwwncwaterorg page 600 Note that because SWAP results and reports are periodically updated by the PWS Section , the results available on this web site may differ from the results that were available at the time this CCR was prepared If you are unable to access your SWAP report on the web , you may mail a written request for a printed copy to Source Water Assessment Program – Report Request , 1634 Mail Service Center , Raleigh NC 27699 -

Maximum Residual Disinfection Level Goal – 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 MRDL - Maximum Residual Disinfection Level – 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 90th Percentile – 90 of samples are equal to or less than the number in the chart ND – Non - Detects – Laboratory analysis indicates that the contaminant is not present at the level of detection set for the particular methodology used NTU – Nephelometric Turbidity Units – A measure of the clarity of water Turbidity in excess of 5 NTU is just noticeable to the average person N A – Not - applicable – Information not applicable not required for that particular water system or for that particular rule Picocuries per liter pCi L – Picocuries per liter is a measure of the radioactivity in the water ppb – parts per billion – 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 ppm – parts per million – milligrams per liter mg l – One part per million corresponds to one minute in two years or a single penny in 10,000 RAA – Running annual average TT – Treatment Technique – A treatment technique is a required process intended to reduce the level of a contaminant in drinking water LRAA – Locational Running Annual Average LRAA – The average of sample analytical results for samples taken at a particular monitoring location during the previous four calendar quarters under the Stage 2 Disinfectants and Disinfection Byproducts Rule Level 1 Assessment - A Level 1 assessment is a study of the water system to identify potential problems and determine if possible why total coliform bacteria have been found in our water system Level 2 Assessment - A Level 2 assessment is a very detailed study of the water system to identify potential problems and determine if possible why an E coli MCL violation has occurred and or why total coliform bacteria have been found in our water system on multiple occasions Water Quality Data Tables of Detected Contaminants We routinely monitor for over 150 contaminants in your drinking water according to Federal and State laws The tables below list all the drinking water contaminants that we detected in the last round of sampling for each particular contaminant group The presence of contaminants does not necessarily indicate that water poses a health risk Unless otherwise noted , the data presented in this table is from analyses completed from January 1 through December 31 , 2022 The EPA and the State allow us to monitor for certain contaminants less than once per year because the concentrations of these contaminants are not expected to vary significantly from year to year Some of the data , though representative of the water quality , is more than one year old Unregulated contaminants are those for which the EPA has not established drinking water standards The purpose of unregulated contaminant monitoring is to assist EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulations are warranted PageWater Quality Data Table s Johnston County WEST PWS # 03 -
