| Q: | Chloramine Public Notice March 7, 2007 |
| For many years, public water systems have added Chloramines to drinking water as a primary or secondary disinfectant. This is because of concerns of formation of disinfection by-product as the result of using free chlorine. The City of Shawnee is conducting a pilot study to evaluate the viability of using Chloramines as post oxidant... |

| Q: | Do I need to buy a water softener? |
| Some companies sell ''water softeners'' to reduce the hardness of the water. The softener's purpose is to improve the aesthetics or ''feel'' of the water. Hard water contains high concentration of calcium compounds. The calcium in the water can deposit on faucets and shower curtains as a heavy white residue (which is most easily cleaned with a rag soaked in vinegar). Shawnee's drinking water hardness fluctuates throughout the year between 75 to 100 parts per million or 4.3 to 6.0 grains per gallon (one grain per gallon equals 17.24 parts per million). Water is considered ''hard water'' above 250 parts per million. Therefore, residents on Shawnee's water supply have soft water, and do not need a softener. By the way, even hard water is fine to use and drink without a softener.

| Q: | How do I know that my water is safe to drink? |
| Shawnee Water Treatment Plant has trained laboratory technicians and uses the service of the ODEQ Environmental Services Laboratory to analyze the quality of the water. Personnel from the lab monitor water quality at the water plant and at homes and businesses around the city to make sure that the water is safe to drink. Sampling and analysis is done continually throughout the year to make certain that the water meets or exceeds all E.P.A. and ODEQ quality standards

| Q: | If chloramines are harmful to fish, how can people safely drink the water? |
| Chloraminated water is no different than chlorinated water for all of the normal uses we have for water. Water that contains chloramines is totally safe to drink. The digestive process neutralizes the chloramines before they reach the bloodstream. Even kidney patients can drink and bathe in chloraminated water. |

| Q: | What are the major benefits associated with chloramination? |
| Better disinfection in the remote areas of the water system, therefore making the water safer to drink. Chloramines greatly reduce objectionable taste and odor in the water. Chloramines have been found to be very effective at reducing levels of by-products that are normally formed with free chlorine. |

| Q: | What is the metal content of the water? |
| Shawnee water is surprisingly low in dissolved metals. The lake water contains negligible amounts (much less than 100 parts per billion) of Silver, Arsenic, Barium, Beryllium, Cadmium, Chromium, Copper, Mercury, Nickel, Lead, Thallium, Selenium, and Antimony. Small amounts (less than 5 parts per million) of naturally occurring Aluminum, Iron, Manganese Sodium, and Zinc are also present in the lake water. The treatment process removes nearly all of these metals from the drinking water. The metals content in the drinking water is always in compliance with E.P.A. guidelines. |

| Q: | What special precautions should fish owners take with chloraminated water? |
| Chloramines are toxic to fish, reptiles, turtles and amphibians, just as chlorine is toxic and must be removed. Chloramines can be removed from the water by using a water conditioner containing a dechlorinator or by using granular activated carbon. |

| Q: | What special precautions should kidney dialysis patients take with chloraminated water? |
| Chlorine and chloramines must be removed from the water used in kidney dialysis machines. There are two methods to accomplish this, by adding ascorbic acid or by using granular activated carbon treatment. Medical centers that perform dialysis are responsible for purifying the water that enters the dialysis machines. Dialysis systems already pre-treat their source water to remove chlorine. However some modifications may be necessary to remove the chloramines. |

| Q: | Where does my water come from? |
| All of Shawnee’s water comes from the Shawnee Twin Lakes and Wes Watkins Reservoir. It flows by gravity from the lakes to the water treatment plant where it undergoes aggressive treatment to remove all particulates and is chlorinated to destroy any pathogens. The water is then pumped to water towers around the city and it flows by gravity to your home. The water treatment plant can treat 8.7 million gallons per day to replenish water as it is used by residents, businesses and industries. |

| Q: | Why are chloramines a problem for kidney dialysis patients and aquarium owners? |
| Chloramines are harmful when they go directly into the bloodstream. In the dialysis process, water comes in contact with the blood across a permeable membrane. Chloramines in dialysis water would be toxic, just as chlorine in dialysis water would be toxic. Fish also take chloramines directly into their bloodstreams. |

| Q: | Why does my water sometime taste or smell like swimming pool water |
| Chlorine is added to the drinking water as a disinfectant (required by Federal Law). The amount added is only enough to ensure that the water at your house is free of bacteria and parasites. Usually, this amount is about 1 milligram of chlorine for each liter of water (1 part chlorine per million parts of water). A slight chlorine odor or no odor indicates that the chlorine is working properly as a disinfectant. Some customers buy sink filters to remove the chlorine for taste reasons. This is fine, but do not let the filtered water set too long since it no longer has its disinfecting abilities.

| Q: | Why does my water sometimes look brown? |
| Brown water occurs when normal sediments in the water lines become agitated. Agitation can occur when the lines are turned off for repairs or when a line breaks. The brown color is from iron (rust) particles that come off the pipes with age. Although it is undesirable, the water is safe to drink. The color can stain white clothes in the washing machine. Try to eliminate the brown color by running your cold water for 15 to 20 minutes (run from an outside faucet). If the color does not go away, contact line maintenance and they will send a worker out to flush the brown water out of the lines at a nearby fire hydrant.

| Q: | Why does my water sometimes look ''milky'' or ''cloudy''? |
| Cloudy water is usually the result of dissolved air in the water lines. Air may be introduced into the lines as a result of line repairs or fire hydrant operations. This condition is usually temporary, although it may take several hours for the air to dissipate in the lines. To check if the cloudy water is due to dissolved air, fill a glass with water and leave it on a counter for a few minutes. The water should become clear again. Cloudy water of this type is safe to use.

| Q: | Will chloramines be removed by boiling the water? |
| No. Boiling is not an effective method of removing chloramines from water. |

| Q: | Will chloramines dissipate, or dissolve, out of the water? |
| No. Unlike chlorine, which dissipates when water sits for a few days, chloramines may take weeks to dissipate. |

| Q: | Will there be any noticeable changes with chloraminated water? |
| When the chloraminated water first flushes out the chlorinated water there may be a slight taste and odor, and possibly discoloration for a short period of time. This will not compromise the safety of the water. Try running your water taps for a few minutes to flush it out. |
