We are changing to chloramines to ensure our water continues to meet or exceed all of the water quality standards set by the Environmental Protection Agency (EPA). Chlorine reacts with naturally occurring organic matter in the water to form what are called disinfection byproducts (DBP’s) which are potentially harmful. These DBP’s are strictly regulated by the EPA. Since chloramine is not as reactive as chlorine, significantly fewer of these DBP’s will be formed. Chloramine is also more stable and extends disinfectant benefits throughout our utility's distribution system. More information
You will not notice any difference in your water quality. Taste and odor issues related to chlorine will be reduced and chloraminated water can be used in all the same ways you've always used our water.
Chloramines, just like chlorine, are harmful to all fish, amphibians and reptiles and must be removed from the water prior to use in aquariums and ponds. Most pet stores sell products that can be easily added to the water to remove chloramines. For more information contact your aquarium supply or pet supply store.
Water from Pittsburgh was found to contain 0.88 parts per billion of chromium. Water from West View – Cranberry?s sole supplier – was not tested. The U.S. Environmental Protection Agency has set a limit of 100.00 ppb in tap water, primarily to safeguard against skin irritation. So Pittsburgh is well within current regulatory requirements.
Other communities tested ranged from as little as zero, including Indianapolis, Reno and San Antonio, to as high as 12.90 ppb in Norman, Oklahoma. Separate research has found that hexavalent chromium is more common in systems using groundwater wells than surface water; West View Water is drawn from the Ohio River.
On December 20, 2010, the American Water Works Association, a trade organization of water professionals, commented that the EPA “is currently looking at new health effects data on hexavalent chromium. The process should be completed in late 2011, and the results will inform future regulatory actions.” They went on to note that while the EWG?s report may raise concerns, “it?s important to remember that detecting a substance in water does not always imply a health risk. The key question to answer is whether the substance presents health concerns at the level it is detected.”
Pressurized water. Water absorbs more air at higher pressures. When this pressurized water experiences a reduction in pressure, such as when it leaves a spigot, it releases air bubbles, resulting in a milky appearance.
Temperature changes. Cold water can hold more air than warm water. When that water warms, air is released. The released air takes the form of small bubbles, which gives the water a milky or carbonated appearance.
Hot water tanks. Water releases air bubbles when it’s heated. When the water heater’s thermostat is set above 140° F, air bubbles will become noticeable, particularly during winter months. It is also noticeable in the first water drawn from a hot water tank after being idle overnight.
Warming cold water lines. When cold water lines in basements, above the ground, or attached to sides of buildings are warmed by internal home heat or exposed to the sun, they can release air bubble
