Water Report
WNorwood purchases the water you drink fromCincinnati Water Works (CWW), which isfamous for its excellent drinking water. TheirGranular Activated Carbon process is consideredthe best way to remove natural and man-madeorganic materials that can affect human health.
In order to make sure all of their treatmentprocesses work, CWW tests the water an averageof 300 times each day. They also have monitorsthroughout the system that test the water contin-uously. Alarms on these monitors make it easy forthem to respond quickly to potential problems.
As additional water quality safeguards, NorwoodHealth Department tests the water CWW provides to us 365 days a year for chlorine resid-ual. We also monitor the water each month forbacteria, and yearly for lead and copper. TheOhio Environmental Protection Agency (EPA)reviews CWW’s and Norwood’s compliance testing results annually.

While CWW provides us with treatedwater, the City of Norwood is responsible
for distributing it, metering it, and billing for thewater service.
As such, we make our own repairs to theNorwood distribution system. Norwood HealthDepartment works closely with the Public Works Department during water main breaks to maintain high water quality while repairs are being made.
City of Norwood personnel are on the job at all times to bring you the cleanest, safest wateravailable. You are welcome to attend public watermeetings held the first Monday of February, May,August, and November from 5-6 pm in the officeof Safety-Service Director.
Who areYou going to Call?• If you have a water break, call the Department
of Public Works at 458-4615.

Whether Norwood drinking water tastes gooddepends on who you ask. Because CWW usescarbon filtration, they don’t need to add as much chlorine as many utilities do, so Norwoodwater has less of a “chemical” taste than water inmany cities.
If you feel your water has a chemical or chlorinetaste, try leaving an open pitcher of it in yourrefrigerator overnight. The chlorine will bereduced by morning and the taste will improve.
While some people like the taste of bottled or home-treated water, these are not necessarilysafer than tap water. The safety of any waterdepends on its source and treatment. For moreinformation about bottled water and home treatment devices, contact the Food and DrugAdministration (FDA) at 1-800-332-4010.

a The EPA has two requirements: 1) That the maximum level found must be less than 5 NTU; and 2) That the level must be under 0.5 NTU 95% of the time.We met both requirements.b Although there is no detectable lead in our drinking water as it leaves the treatment plants, by the time it reaches your tap, lead levels may vary.c EPA considers 50 pCi/L to be the level of concern for beta particles.d Coliforms are used as indicator that other potentially - harmful bactreria may be present. In 2009, no samples were positive for coliform bacteria.e The value in “Highest level used to determine complience” for Total Organic Carbon (TOC) is the lowest ratio between percentage of TOC actually removed to the percentage of TOC required
to be removed.A value of greater than 1 indicates the water system is in compliance with TOC removal requirements; a value less than 1 indicates a violation of TOC removal requirements.
Water Quality Data **DefinitionsMaximum Contaminant Level Goal orMCLG: The level of a contaminant in drinking water below which there is noknown or expected risk to health. MCLGsallow for a margin of safety.
Maximum Contaminant Level or MCL: Thehighest level of a contaminant that is allowedin drinking water. MCLs are set as close to theMCLGs as feasible using the best available treatment technology.
Action Level or AL: The concentration of a contaminant, which, if exceeded, triggerstreatment or other requirements which awater system must follow.
Treatment Technique or TT: A requiredprocess intended to reduce the level of a contaminant in drinking water.
The < symbol: A symbol which means lessthan. A result of <5 means that the lowestlevel that could be detected was 5 and thecontaminant in that sample was not detected.
Abbreviationsppb: parts per billion or micrograms per liter ppm: parts per million or milligrams per liter na: not applicable NTU: Nephelometric Turbidity Unit, used to measure cloudiness in drinking water nd: not detectable at testing limits nr: not regulated pCi/L: picoCuries per liter, a measure ofradioactivity in waterug/L: micrograms per liter
Total Coliform BacteriaThe Norwood Water System did not incur
any violations in 2009 for bacteria indrinking water. We continue to monitor forthe presence of bacteria on a weekly basis.
What can be in DrinkingWater? What can be in DrinkingWater?Drinking water, including bottled water, may reason-ably be expected to contain at least small amounts ofsome contaminants. The presence of contaminantsdoes not necessarily indicate that water poses a healthrisk. More information about contaminants and poten-tial health effects can be obtained by calling the SafeDrinking Water Hotline (1-800-426-4791).
The sources of drinking water (both tap and bottled)include rivers, lakes, streams, ponds, reservoirs, springsand wells. As water travels over the surface of the landor through the ground, it dissolves natural minerals,and in some cases, natural radioactive materials. It can also pick up substances resulting from human or animal activity.
Contaminants that may be present in source waterinclude:
1. Microbes, such as viruses and bacteria, which maycome from sewage treatment plants, septic systems,livestock or wildlife
2. Inorganics, such as salts and metals, which can benatural or come from stormwater runoff, industrialor domestic wastewater discharge, oil and gas production, mining or farming
3. Pesticides and herbicides, which may come fromfarm or home uses, or stormwater runoff
4. Organics, including synthetic and volatile organicchemicals, which are created through industrialprocesses and gas/oil products, and can also come from gas stations, stormwater runoff and septic systems
5. Radioactive substances, which can be natural or theresult of oil and gas production or mining
CWW uses the latest treatment techniques to removeharmful contaminants. In order to ensure that tapwater is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health.
The Health Connection
Some people may be more vulnerable to contaminantsin drinking water than the general population:
1. Immuno-compromised persons, such as personswith cancer undergoing chemotherapy, persons whohave undergone organ transplants, people withHIV/AIDS or other immune system disorders, someelderly, and infants can be particularly at risk of infec-tions. These people should seek advice about drinkingwater from their health care providers. EPA/CDCguidelines on appropriate means to lessen the risk ofinfection by Cryptosporidium* and other microbial contaminants are available from the EPA SafeDrinking Water Hotline (1-800-426-4791).
2. Infants and young children can have more troublewith lead in drinking water than other people. It ispossible that lead levels in your home may be higherthan in other homes in the community because ofmaterials used in your home’s plumbing. If you areconcerned about high lead levels, you may wish to
have your water tested. Flushing your tap for up to twominutes before using the water and using only coldwater for cooking are also helpful.
*Cryptosporidium GCWW has tested for Cryptosporidum (Crypto)in treated waters and has never detected it. Crypto is a microscopicmicroorganism that, when ingested, can result in diarrhea, feverand other gastrointestinal symptoms. GCWW also tested forCrypto in the Ohio River surface water and it was not found insamples during 2009. The organism is found in surface waters andcomes from animal and human wastes which enter the watershed.Crypto is eliminated by an effective combination including sedi-mentation, filtration, and disinfection.
But what’s in Norwood Drinking Water?
The table below contains the substances found inCWW water provided to Norwood in 2009. Datashow results of monitoring required by EPA. GCWWhas tested for sodium in treated water as it leaves thetreatment plants and has found 24 mg (milligrams)per liter in the Miller water and 34 mg per liter in theBolton water. There are approximately 4 cups in a liter.All of the regulated substances in CWW drinkingwater were well within limits EPA has set to ensuresafety of tap water.
The lead, copper, and chlorine residual data show theresults of Norwood testing in 2009. These substanceswere also within EPA limits.
Norwood residents receive their water from the Miller Treatment Plant which treats water from the Ohio River. The Ohio River, along with all surface waters, hasbeen classified as highly susceptible to contamination by the Ohio E.P.A. because it is open to the environment and pollution spreads quickly with the flow of water.
Several barriers are in place between potential pollution & your tap water: 1) source water protection program monitors & prevents contamination in the river withthe help of the Ohio River Valley Water Sanitation Commission & other utilities; 2) turning off intake until pollution passes or altering treatment process to removecontamination; 3) granular activated carbon (GAC) daily to remove most common chemicals found in spills.
