Public Wholesale WSD 13

The Division of Natural Resources conducts regular water assessments to evaluate potential contamination risks to our municipal supply. This includes mapping source water regions and conducting comprehensive contaminant inventories to protect public health.

You can access detailed assessment maps at http://maproom.missouri.edu/swipmaps/pwssid.htm using our system identification code found at the top of this report. These resources provide a foundation for developing more comprehensive source water protection strategies.

Why might contaminants appear in your tap water? All water, including bottled varieties, naturally contains some level of contaminants. Their presence doesn't necessarily indicate a health risk. For more information about contaminants and potential health effects, contact the Environmental Protection Agency's Safe Drinking Water Hotline at 800-426-4791.

Potential contaminant sources include:

• Microbial contaminants from sewage treatment, septic systems, agricultural operations, and wildlife
• Inorganic contaminants like salts and metals occurring naturally or from stormwater runoff, industrial discharges, oil/gas production, mining, and farming
• Pesticides and herbicides from agriculture, urban runoff, and residential uses
• Organic chemical contaminants, including synthetic and volatile compounds from industrial processes, petroleum production, gas stations, stormwater runoff, and septic systems
• Radioactive contaminants occurring naturally or resulting from oil/gas production and mining

The Missouri Department of Natural Resources regulates our water system and requires regular testing to ensure safety. Our system identification number MO1010548 helps track our compliance with state regulations and standards.

Special precautions: Some individuals may be more vulnerable to water contaminants than the general population. People with compromised immune systems, including those undergoing chemotherapy, organ transplant recipients, HIV/AIDS patients, elderly individuals, and infants could face heightened infection risks. These individuals should seek medical advice about their drinking water. EPA/CDC guidelines on reducing Cryptosporidium and other microbial contaminant risks are available from the Safe Drinking Water Hotline (800-426-4791).

Common Questions About Your Municipal Water

Who provides my water service?
The Dare County Public Water Supply System operates five separate distribution networks serving: Southern Shores, Duck, Kitty Hawk, Colington, unincorporated areas of Roanoke Island not served by Manteo, Stumpy Point, Rodanthe, Waves, Salvo, Avon, Buxton, Frisco, and Hatteras.

What's the source of our water?
We operate five treatment facilities. Four use Reverse Osmosis to desalinate groundwater from wells 300-400 feet deep. These plants are in Kill Devil Hills, Stumpy Point, Rodanthe, and Frisco. Our fifth facility on Roanoke Island treats fresher well water (200 feet deep) using Anion Exchange and Nanofiltration technologies.

How does Reverse Osmosis work?
Reverse Osmosis (RO) pumps water through special membranes that remove impurities. Our automated system eliminates over 97% of dissolved minerals from well water.

What are the fluoride and sodium levels?

1. Fluoride: 0.75 parts per million (ppm). North Carolina's maximum allowable level is 4.0 ppm, with a recommended range of 0.7-1.0 ppm for cavity prevention. All treatment chemicals are computer-controlled to balance dental health benefits while avoiding excessive exposure.
2. Sodium: Levels vary by plant - 100-120 ppm at Skyco and KDH facilities, 40-60 ppm at Rodanthe. The maximum allowable level is 250 ppm. Customers on moderate sodium-restricted diets (270mg daily) should limit consumption to about half a gallon of tap water daily. Those on strict sodium diets (20mg daily) should use bottled water.

Where can I have my water tested?
Each of our five treatment facilities has a staffed laboratory that provides free water testing for customers. If you have concerns, please call us for same-day response when possible.

What are the minimum billing charges?
Metered accounts are charged a base rate starting at $38.20 for 3/4-inch connections (includes 0-3000 gallons). Non-metered accounts start at $15.41, with rates based on meter size. This base charge applies every billing cycle.

Do you offer leak adjustments?
Yes, we can adjust your bill if you provide proof of water leak repair.

Can I pay my bill with a credit card?
Yes, we accept MasterCard, Visa, and American Express. Online payments can be made at https://darencfin.munisselfservice.com/citizens/UtilityBilling/Default.aspx or by calling 1-888-272-9829 (jurisdiction code 3955). You'll need your account number when calling.
