thereby concentrating fecaldeposits at the intake and thuscompromising the source waterquality. Conversely, the shoreintakes are highly susceptible tostorm water runoff, marinas andshoreline point sources due to theinflux of groundwater to the lake.

Drinking water, including bottledwater, may reasonably be expectedto contain at least small amounts ofsome contaminants. The presence

of contaminants doesnot necessarilyindicate that waterposes a health risk.More informationabout contaminantsand potential health

effects can be obtained by callingthe EPA’s Safe Drinking WaterHotline (1–800–426–4791).

Some people may be morevulnerable to contaminants indrinking water than the generalpopulation. Immuno-compromisedpersons such as persons withcancer undergoing chemotherapy,persons who have undergoneorgan transplants, people withHIV/AIDS or other immune systemdisorders, some elderly, and infantscan be particularly at risk frominfections. These people shouldseek advice about drinking waterfrom their health care providers.EPA/Center of Disease Controlguidelines on appropriate

The City of Country Club Hillsreceives our water supply from theCity of Chicago. The City ofChicago processes surface waterfrom Lake Michigan.

The Illinois EPA hascompleted its sourcewater assessmentprogram (SWAP). TheIllinois EPA considersall surface watersources of community water supplyto be susceptible to potentialpollution problems. The very natureof surface water allowscontaminants to migrate into theintake with no protection onlydilution. This is the reason formandatory treatment for all surfacewater supplies in Illinois. Chicago’soffshore intakes are located at adistance that shoreline impacts arenot usually considered a factor onwater quality. At certain times of theyear, however, the potential forcontamination exists due to wet-weather flows and river reversals.In addition, the placement of thecrib structures may serve to attractwaterfowl, gulls and terns thatfrequent the Great Lakes area,

We are pleased to present to youthe 2016 Annual Quality WaterReport. This report is designed toinform you about the quality ofwater we deliver to you every day.Our constant goal is to provide youwith a safe and dependable supplyof drinking water.

WATER QUALITY REPORT Inorganic contaminants,

such as salts and metals, whichcan be naturally occurring orresult from urban stormwaterrunoff, industrial, or domesticwastewater discharges, oil and gasproduction, mining or farming;

Pesticides and herbicides,

which may come from a variety ofsources such as agriculture, urbanstormwater runoff and residentialuses;

Organic chemical contaminants,

including synthetic and volatileorganic chemicals, which are by–products of industrial processesand petroleum production, andcan also come from gas stations,urban stormwater runoff andseptic systems;

Radioactive contaminants,

which may be naturally occurringor be the result of oil and gasproduction and mining activities.

Other contaminants,

in order to ensure that tap wateris safe to drink, EPA prescribesregulations that limit the amountof certain contaminants in waterprovided by public water systems.FDA regulations establish limits forcontaminants in bottled water,which must provide the sameprotection for public health.

In addition to the informationalsection of the Water QualityReport, we have included for yourreview several tables. The tableswill give you a better picture ofthe contaminants that weredetected in your water and thecontaminants that were tested forbut not detected.

(Continued from page 1)

means to lessen the risk ofinfection by cryptosporidium andother microbial contaminants areavailable from the Safe DrinkingHotline: (1-800-426-4791).

The sources of drinking water(both tap water and bottledwater) include rivers, lakes,streams, ponds, reservoirs, springsand wells. As water travels overthe surface of the land or throughthe ground, it dissolves naturallyoccurring minerals and in somecases, radioactive material, andcan pick up substances resultingfrom the presence of animals orfrom human activity. Possiblecontaminants consist of:

Microbial contaminants,

such as viruses and bacteria,which may come from sewagetreatment plants, septic systems,agricultural livestock operationsand wildlife;

COUNTRY CLUB HILLS MUNICIPAL SEWER USE ORDINANCEEvery year there are over 15,000 sewer overflows in Illinois. Many of these are directly related to

the improper disposal of oil and grease into household drains. Grease blocks sewer pipes and causes

wastewater to back up into homes and businesses.

Dumping oil and grease into municipal sewer lines is preventable by following the instructions on

the other side of this card. For further information on the City sewer use ordinance, visit our web site

at countryclubhills.org, then go to Municipal Codes, Chapter 18, Combined Water & Sewer System,

Article 6 - Sewer Regulation, or call the Water Department at 708-799-1390.

WATER QUALITY REPORT

MCLG: Maximum Contaminant Level Goal, orthe level of a contaminant in drinking waterbelow which there is no known or expectedrisk to health. MCLGs allow for a margin ofsafety.

MCL: Maximum Contaminant Level, or thehighest level of a contaminant that is allowedin drinking water. MCLs are set as close to theMCLGs as feasible using the best availabletreatment technology.

TT:Treatment Technique or a required processintended to reduce the level of a contaminantin drinking water.

Level Found:This column represents anaverage of sample result data collected duringthe CCR calendar year. In some cases, it mayrepresent a single sample if only one samplewas collected.

Range of Detections:This columnrepresents a range of individual sampleresults, from lowest to highest that werecollected during the CCR calendar year.

Maximum Residual Disinfectant LevelGoal or MRDLG:The level of a drinkingwater disinfectant below which there is noknown or expected risk to health. MRDLGs donot reflect the benefits of the use ofdisinfectants to control microbialcontaminants.

Maximum Residual Disinfectant Levelor MRDL:The highest level of a disinfectantallowed in drinking water. There is convincingevidence that addition of a disinfectant isnecessary for control of microbialcontaminants.

Date of Sample - If a date appears in the“Date of Sample” column, the Illinois EPArequires monitoring for this contaminant lessthan once per year because theconcentrations do not frequently change. If nodate appears in the column, monitoring forthis contaminant was conducted during theCCR calendar year.

AL – Action Level. The concentration of acontaminant which, when exceeded, triggerstreatment or other requirements which awater system must follow.

nd – Not Detectable at testing limits.

n/a – not applicable.

ppm – parts per million - or one ounce in7,350 gallons of water.

ppb – parts per billion - or one ounce in7,350,000 gallons of water.

pCi/l – picocuries per liter, used to measureradioactivity.

NTU – Nephelometric Turbidity Unit, used tomeasure cloudiness in drinking water.

%<0.5 NTU – Percent samples less than 0.5NTU.

#pos/mo – number of positive samples permonth.

In most cases, the “Level Found” columnrepresents an average of sample result datacollected during the reporting year. The“Range of Detections” column represents arange of individual sample results, from lowestto highest that were collected during thereporting year. If a date appears in the “Date ofSample” column, the Illinois EPA requiresmonitoring for this contaminant less thanonce per year because the concentrations donot frequently change. If no date appears inthe column, monitoring for this contaminantwas conducted during the reporting year.

TurbidityTurbidity is a measure of the cloudiness of thewater. We monitor it because it is a good indicatorof water quality and the effectiveness of ourfiltration system and disinfectants.

FluorideFluoride is added to the water to help promotestrong teeth. The Illinois Department of PublicHealth recommends an optimal fluoride range of0.9 mg/l to 1.2mg/l.

LeadIf present, elevated levels of lead can cause serioushealth problems, especially for pregnant womenand young children. Lead in drinking water isprimarily from materials and componentsassociated with service lines and home plumbing.We cannot control the variety of materials used inplumbing components. When your water has beensitting for several hours, you can minimize thepotential for lead exposure by flushing your tapfor 30 seconds to 2 minutes before using water fordrinking or cooking. If you are concerned aboutlead in your water, you may wish to have yourwater tested. Information on lead in drinking

water, testing methods, and steps you can take tominimize exposure is available from the SafeDrinking Water Hotline or athttp://www.epa.gov/safewater/lead.

SodiumThere is not a state or federal MCL for sodium.Monitoring is required to provide information toconsumers and health officials that are concernedabout sodium intake due to dietary precautions. Ifyou are on a sodium-restricted diet, you shouldconsult a physician about this level of sodium inthe water.

Voluntary TestingThe Chicago Water Department monitors forcontaminants which are proposed to be regulatedor for which no standards currently exist butwhich could provide useful information inassessing the quality of the source water or thedrinking water.

The Department of Water Management has addedtesting methods to those already performed toassess water quality. The objective of the additionaltesting is to detect changes in water quality in atimely manner. Protocol for screening watersamples for toxicity from chemicals and also forscreening water samples for the presence ofendospores has been developed.

2014 Voluntary MonitoringSince the end of the official monitoring period inNovember 2008 of the Long Term 2 EnhancedSurface Water Treatment Rule (LT2ESWTR), theCity of Chicago has continued monitoring forCryptosporidium, Giardia and E. Coli in its sourcewater as part of its water quality program. To date,Cryptosporidium has not been detected in thesesamples, but Giardia was detected in 2010 in oneraw lake water sample collected in September2010. Treatment processes have been optimized toprovide effective barriers for removal ofCryptosporidium oocysts and Giardia cysts in thesource water, effectively removing these organismsin the treatment process. By maintaining lowturbidity through the removal of particles fromthe water, the possibility of Cryptosporidium andGiardia organisms getting into the drinking watersystems is greatly reduced.

WATER QUALITY REPORT

The City of Chicago Department of WaterManagement (CDWM) has completed a waterquality study to monitor some compoundsthat have not historically been considered tobe contaminants of concern, but have beenrecently documented at trace concentrationsin our nation’s waterbodies. This study,completed in the years 2009 - 2011, includescompounds known as Endocrine DisruptingChemicals (EDCs) and Pharmaceuticals &Personal Care Products (PPCPs), which areconsidered to be emerging contaminants.EDCs are compounds with potential tointerfere with natural hormone systems.PPCPs are a group of compounds consistingof prescription or over-the-countertherapeutic drugs, veterinary drugs, andconsumer products such as sun-screen,.lotions, insect repellent, and fragrances. The

reader is encouraged to visit the UnitedStates Environmental Protection Agency(USEPA) website to learn more about EDCs(http://www.epa.gov/ncer/science/endocrine/) and PPCPs(http://www.epa.gov/ppcp/).In 2014, CDWM has also monitored for

hexavalent chromium, also known aschromium-6, and continues to do soquarterly. USEPA has not yet established astandard for chromium-6, a contaminant ofconcern which has both natural andindustrial sources. Please address anyquestions or concerns to DWM’s WaterQuality Division at 312-742-7499. A list ofdetected contaminants from the monitoringstudies and additional information is postedon the City’s website which can be accessedat the following address below:
