Water Quality Preventative Maintenance Program

 

In our continuing effort to improve water quality, the City of Archdale and the Piedmont Triad Regional Water Authority will participate in a routine Water Quality Preventative Maintenance Program beginning on March 5, 2018 and ending May 11, 2018.

During this time, the Piedmont Triad Regional Water Authority will temporarily discontinue the use of the chloramines disinfection that is currently being used and begin using chlorine disinfection. The water produced by the Piedmont Triad Regional Water Authority and distributed by the City of Archdale will continue to meet Federal and State safe drinking water standards and be safe for consumption and use.

Why Change Disinfectants?

This periodic Water Quality Preventative Maintenance Program process change is strongly recommended by the Environmental Protection Agency (EPA) and the State of North Carolina to preserve water quality by ensuring that persistent levels of disinfection exist within the City of Archdale and the Piedmont Triad Regional Water Authority’s water distribution system.

What Should I Expect?

During the switch of disinfectant products, some users may notice temporary color, taste, and odor differences. This is a normal part of the process and customers should be reassured that water quality will not be affected.

It is recommended that customers continue to remove chloramines and chlorine from water prior to use in the kidney dialysis process, fish, aquarium and pond maintenance, and with some types of manufacturing practices. Customers are advised to seek professional advice concerning the removal methods for chlorine and chloramines for those applications.

Frequently Asked Questions

      1. What is the Water Quality Preventative Maintenance Program?

It is a process that will involve a temporary switch from the present water disinfectant product, chloramines, to a chlorine water disinfectant product in order to optimize water quality in our distribution systems.

  1. When will the Water Quality Preventative Maintenance Program occur?

Water utilities in Archdale, Burlington, Greensboro, High Point, Jamestown, Piedmont Triad Regional Water Authority, Randleman, Reidsville and their municipal water customers will participate in the Water Quality Preventative Maintenance Program from March 5 to May 11, 2018.

  1. What is chlorine?

Chlorine is a type of water additive used by municipal water systems to disinfect your drinking water.

  1. What are chloramines?

Chloramine is a type of disinfectant used in drinking water to remove the impurities consisting of both chlorine and ammonia. In the chloramination process, ammonia is added to the water at a carefully controlled level. The chlorine and ammonia react chemically to produce chloramines. Chloramination is as effective as chlorine in killing many kinds of bacteria and other germs that may be harmful to personal health.

  1. Why convert from chlorine to chloramines?

Chloramination reduces the level of certain byproducts of the chlorination process. These byproducts, called Total Trihalomethanes (TTHM) and Haloacetic Acids (HAAs), result from the reaction of chlorine with the small amounts of naturally occurring organic substances in drinking water. TTHMs and HAAs are suspected carcinogens (cancer-causing substances) when present at elevated levels and consumed over many years. By converting to chloramines, the regional partnership:

  • reduces the levels of TTHMs and HAAs in drinking water
  • complies with more stringent standards implemented by the Environmental Protection Agency (EPA)
  • continues to supply water customers with safe and aesthetically pleasing water
  1. Is chlorination and chloramination safe?

Yes. Chlorinated and chloraminated drinking water is perfectly safe for drinking, cooking, bathing, and other daily water uses, though there may be a slight change in the water’s taste or odor. There are however, some identified groups who need to take special precaution with chlorinated and chloraminated water such as customers who use drinking water for kidney dialysis machines, specialized industries, and fish owners.

  1. How are kidney dialysis patients affected by chlorine/chloramines and what precautions should they take?

Chlorine and chloramines are harmful when they go directly into the bloodstream. In the dialysis process, the water mixes with blood across a permeable membrane. For this reason, both chloramines and chlorine are toxic in dialysis water and must be removed from water used in dialysis machines. Medical centers that perform dialysis are responsible for purifying water used in their dialysis machines. Each municipality will work closely with physicians, clinics, and medical facilities in their communities to ensure they are aware of the need to remove chlorine and chloramines. Customers with home dialysis equipment should contact their physicians and check with equipment manufacturers for more information.

  1. Is it safe for kidney dialysis patients to drink water containing chlorine and/or chloramines?

Yes, it is safe for kidney dialysis patients to drink chlorinated and chloraminated water. During the digestive process, chlorinated and chloraminated water is metabolized before reaching the bloodstream. All kidney dialysis facilities and users of home dialysis machines are advised to seek professional advice concerning the removal methods for chlorine and chloramines.

  1. How are fish affected by chlorine/chloramines and what precautions should fish owners take?

Fish also take chlorine and chloramines directly into their bloodstream. Chlorine and chloramines should be removed from water used in aquariums, fish tanks, and ponds. Individuals or businesses that keep fish or other animals in tanks, aquariums, or ponds should ask a pet supply company about removing chlorine and chloramines. Customers who use drinking water for aquaculture purposes (growing plants in water tanks or ponds) should get expert advice regarding the need and procedures to neutralize or remove chlorine and chloramines. Also, restaurants and grocery stores with lobster tanks must take special precautions to treat the water.

  1. Is it safe to wash open wounds with chlorinated/chloraminated water?

Yes. Chlorinated and Chloraminated water is completely safe to use on cuts and wounds. Water cannot enter the bloodstream through an open cut.

  1. Will chlorination/chloramination affect business water users?

Businesses and other establishments that use municipal drinking water for commercial laundering, laboratory procedures, and other processes that require carefully controlled water characteristics should get advice from equipment manufacturers or other suppliers regarding any changes that may be needed. These types of businesses may include but not limited to laboratories, microchip manufacturers, biotech companies, soft drink bottlers, photography labs, and restaurants or seafood suppliers with fish tanks.

  1. What actions do I take concerning swimming pool maintenance?

Contact your local pool suppliers for specific details concerning treatment of chlorinated and chloraminated water.

  1. Do home water softeners remove chlorine/chloramines?

Most water softeners are not designed to remove chlorine or chloramines. Contact the manufacturer for specific details.
