We want to keep you informed about the excellent water and services we have delivered to you over the past year. Our goal is and always has been, to provide to you a safe and dependable supply of drinking water. Our staff receives updated, professional training on a continuing basis so that we may better serve you. At the present there are over 150 water customers and users on the system, consisting of more than 1.5 miles of water distribution pipe within Furnace Creek. There is one partially buried tank located in Furnace Creek that holds approximately 2‐million gallons of water. We are chlorinating, we do so as a protection to our customers and users. Chlorinating kills bacteria that might enter our system. Another question frequently asked of our department is “do you fluoridate”? The answer is “no”. We’re pleased to report that our drinking water is safe and meets or exceeds state water board requirements. This report shows our water quality and what it means. If you have any questions about this report or concerns of your water utility, please contact Charles Thompson, at 760‐786‐3262. We want our customers and users to be informed about their water utility. If you want to learn more, please do not hesitate to contact Maintenace Division Chief. Death Valley Utilities Branch routinely monitors for constituents in our drinking water according to State laws. Our water system is tested monthly. The attached report shows the results of our monitoring for the period of January 1st to December 31st, 2023.

Drinking Water Source Assessment Information:A source water assessment was conducted for all Furnace Creek wells in January 2009. Sources were considered vulnerable to water supply and monitoring wells. Arsenic, fluoride, and general minerals were detected but are not attributed to activities and are considered naturally occurring. Reverse osmosis treatment is provided for these. A copy of the complete assessment may be viewed at the Death Valley National Park office or requested from the State Water Resources Control Board, Division of Drinking Water at (909) 383-4328 or 464 West 4th Street, Suite 437, San Bernardino, CA 92401.The water is considered moderately mineralized consisting of sodium, calcium and magnesium, salts and bicarbonate, fluoride, arsenic, and chloride. The water is considered high silica water in which amorphous silica and magnesium silicate deposits could create serious problems by fouling surfaces of water handling equipment. This type of silica scale is very tenacious and difficult to remove.Specific water quality data relating to system water supplies can be found below.

Sources of Drinking Water and Contaminants that May Be Present in Source WaterThe 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:
Regulation of Drinking Water and Bottled Water QualityIn order to ensure that tap water is safe to drink, the U.S. EPA and the State Board prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. The U.S. Food and Drug Administration regulations and California law also establish limits for contaminants in bottled water that provide the same protection for public health.About Your Drinking Water QualityDrinking Water Contaminants DetectedTables 1, 2, 3, 4, 5, 6, and 8 list all of the drinking water contaminants that were detected during the most recent sampling for the constituent. The presence of these contaminants in the water does not necessarily indicate that the water poses a health risk. The State Board allows us to monitor for certain contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of the data, though representative of the water quality, are more than one year old. Any violation of an AL, MCL, MRDL, or TT is asterisked. Additional information regarding the violation is provided later in this report.Table 1. Sampling Results Showing the Detection of Coliform BacteriaComplete if bacteria are detected.

Additional General Information on Drinking WaterDrinking 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 the water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the U.S. EPA’s Safe Drinking Water Hotline (1-800-426-4791).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. U.S. EPA/Centers for Disease Control (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 (1-800-426-4791).Lead-Specific Language: 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. [Enter Water System’s Name] 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. [Optional: If you do so, you may wish to collect the flushed water and reuse it for another beneficial purpose, such as watering plants.] If you are concerned about lead in your water, you may wish to have your water tested.

Report Date: August 16, 2024 Type of Water Source(s) in Use: Ground water Name and General Location of Source(s): The Cow Creek water supply is collected from the Nevares Spring’s infiltration gallery which is located about two miles east of the Cow Creek housing area. Drinking Water Source Assessment Information: A source water assessment was conducted for the sources of the Death Valley National Park public water systems in May 2002. The Nevares Spring is not considered vulnerable to any potentially contaminating activities at this time. The detection of arsenic and fluoride is considered naturally occurring. Reverse osmosis treatment is provided for these.

Sources of Drinking Water and Contaminants that May Be Present in Source Water
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, that can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
- Pesticides and herbicides, that may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.
- Organic chemical contaminants, including synthetic and volatile organic chemicals, that are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, agricultural application, and septic systems.
- Radioactive contaminants, that can be naturally occurring or be the result of oil and gas production and mining activities.
Regulation of Drinking Water and Bottled Water Quality
In order to ensure that tap water is safe to drink, the U.S. EPA and the State Board prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. The U.S. Food and Drug Administration regulations and California law also establish limits for contaminants in bottled water that provide the same protection for public health.About Your Drinking Water Quality
