Public Water System ID Number: AZ04-03712Public Water System Name: Glen Canyon NRA WahweapContact Name, Phone, and Email: Adam Rymer, 828-507-8457, Adam_Rymer@nps.govWe want our valued customers to be informed about their water quality. If you would like to learn more about public participation or to attend any of our regularly scheduled meetings, please contact Rich Sweeting at 928-608-6341 for additional opportunity and meeting dates and times. Drinking Water SourcesThe sources of drinking water (both tap 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 substance’s resultant from the presence of animals or from human activity.To ensure that tap water is safe to drink, EPA prescribes regulations which limit the number of certain contaminants in water provided by public water systems. Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled water which must provide the same protection for public health. Our water source(s):Groundwater Well # U037121 – Utah 4 Drinking Water ContaminantsContaminants are any physical, chemical, biological, or radiological substance or matter in water. Contaminants that may be present in source water include: Vulnerable PopulationDrinking 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. In order to ensure that tap water is safe to drink, the Environmental Protection Agency (EPA) prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. The Food and Drug Administration (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. More information about contaminants, their potential health effects, and the appropriate means to lessen the risk can be obtained by calling the Environmental Protection Agency's Safe Drinking Water Hotline at 800-426-4791 or visiting the website epa.gov/safewater. Source Water AssessmentMaking the water safe to drink starts by protecting the place it comes from. We work with state scientists at the Arizona Department of Environmental Quality (ADEQ) to examine water at its source to look for possible pollutants. This is called a Source Water Assessment (SWA). Based on the information available at the time of the assessment on the hydrogeology and land uses around the drinking water source(s) of this public water system, the Arizona Department of Environmental Quality (ADEQ) has given a low vulnerability designation for the degree to which this public water system drinking water source(s) are protected. DefinitionsMaximum Contaminant Level (MCL): 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 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. Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water. Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. Maximum residual disinfectant level goal or 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. 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. Level 1 Assessment: 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 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. Lead Informational Statement: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. GLEN CANYON NRA WAHWEAP is responsible for providing high quality drinking water and removing lead pipes, but cannot control the variety of materials used in plumbing components in your home. You share the responsibility for protecting yourself and your family from the lead in your home plumbing. You can take responsibility by identifying and removing lead materials within your home plumbing and taking steps to reduce your family's risk. Before drinking tap water, flush your pipes for several minutes by running your tap, taking a shower, doing laundry or a load of dishes. You can also use a filter certified by an American National Standards Institute accredited certifier to reduce lead in drinking water. To address lead in drinking water, public water systems were required to develop and maintain an inventory of service line materials by Oct 16, 2024. Developing an inventory and identifying the location of lead service lines (LSL) is the first step for beginning LSL replacement and protecting public health. The lead service inventory may be viewed online at: www.120water.com. Please contact us if you would like more information about the inventory or any lead sampling that has been done. If you are concerned about lead in your water and wish to have your water tested, contact GLEN CANYON NRA WAHWEAP GLCA Utility Supervisor Ky_Macktima-Borhauer@nps.gov or (928) 614-9197. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at http://www.epa.gov/safewater/lead. Water Quality Data – Regulated ContaminantsThe following are terms related to water quality data presented in this table:Not Applicable (NA): Sampling was not completed because it was not required by regulation. Not Detected (ND or <): Not detectable at reporting limit. Minimum Reporting Limit (MRL): The smallest concentration of a substance that can be reliably measured by a given analytical method. Millirems per year (MREM): A measure of radiation absorbed by the body. Nephelometric Turbidity Units (NTU): Measure of water clarity. Million fibers per liter (MFL): Measure of asbestos fibers. Picocuries per liter (pCi/L): Measure of the radioactivity in water. ppm: Parts per million or Milligrams per liter (mg/L), equal to 1/1000 of a gram. ppb: Parts per billion or Micrograms per liter (µg/L), equal to 1000 ppm. ppt: Parts per trillion or Nanograms per liter (ng/L), equal to 1000 ppb.ppq: Parts per quadrillion or Picograms per liter (pg/L), equal to 1000 ppt.
