SWANSEA WATER DISTRICT’S

2016 DRINKING WATER QUALITY REPORT

 

PORTUGUESE SUB-POPULATION LANGUAGE STATEMENT

(ESTE ORIGINAL É IMPORTANTE E DEVE SER TRADUZIDO IMEDIATEMENTE.)

THE SWANSEA WATER DISTRICT (PUBLIC WATER SUPPLIER IDENTIFICATION NUMBER 4292000) FURNISHES THIS REPORT ANNUALLY IN ACCORDANCE WITH THE PROVISIONS OF THE SAFE DRINKING WATER ACT. THE REPORT DETAILS INFORMATION ABOUT YOUR WATER SUPPLY.

 

THE SWANSEA WATER DISTRICT HAS TEN (10) WELLS WITH THREE TREATMENT PLANTS DISTRIBUTED THROUGHOUT ITS SERVICE AREA. THESE WELLS PUMP GROUNDWATER FROM THE SAND AND GRAVEL AQUIFER WITH ONE (1) DERIVING ITS WATER SOURCE FROM FISSURES IN BEDROCK. ADDITIONALLY, THE DISTRICT NOW OPERATES A DESALINATION FACILITY WHICH CONVERTS SALT WATER FROM THE PALMER RIVER INTO DRINKING WATER. TYPICALLY, YOU SHALL RECEIVE WATER FROM THE WELL OR TREATMENT PLANT LOCATED CLOSEST TO YOUR LOCATION. HOWEVER, THIS MAY CHANGE AT ANY TIME BECAUSE WATER QUALITY VARIES SLIGHTLY BASED ON THE CHARACTERISTICS OF THE SOURCE WATER WHEN IT COMES FROM ANOTHER WELLSITE DUE TO WATER DEMAND AND MAINTENANCE SCHEDULING.

 

ALL OF THE WATER PRODUCED BY THE DISTRICT IS TREATED FOR CONTROL OF PIPING CORROSION, CHLORINE FOR CONTROL OF BACTERIAL GROWTH AND FLUORIDE FOR PREVENTION OF DENTAL CAVITIES.

 

THE SOURCES OF DRINKING WATER FOR BOTH TAP WATER AND BOTTLED WATER THROUGHOUT OUR COUNTRY INCLUDE RIVERS, LAKES, STREAMS, PONDS, RESERVOIRS, SPRINGS AND WELLS. AS WATER TRAVELS OVER THE SURFACE OF THE LAND OR THROUGH THE GROUND, IT DISSOLVES NATURALLY OCCURRING MINERALS AND, IN SOME CASES, RADIOACTIVE MATERIAL. IT ALSO CAN PICK UP SUBSTANCES RESULTING FROM THE PRESENCE OF ANIMALS OR FROM HUMAN ACTIVITY. THESE FOREIGN MATERIALS ARE REFERRED TO AS CONTAMINANTS.

 

CONTAMINANTS THAT MAY BE PRESENT IN SOURCE WATER BEFORE TREATMENT INCLUDE:

 

MICROBIAL CONTAMINANTS SUCH AS VIRUSES AND BACTERIA, WHICH MAY COME FROM SEWAGE TREATMENT PLANTS, SEPTIC SYSTEMS, AGRICULTURAL LIVESTOCK OPERATIONS, AND WILDLIFE.

 

INORGANIC CONTAMINANTS SUCH AS SALTS AND METALS, WHICH CAN BE NATURALLY OCCURRING, OR RESULT FROM URBAN STORMWATER RUNOFF, INDUSTRIAL OR DOMESTIC WASTEWATER DISCHARGES, OIL AND GAS PRODUCTION, MINING, OR FARMING.

 

PESTICIDES AND HERBICIDES WHICH MAY COME FROM A VARIETY OF SOURCES SUCH AS AGRICULTURE, URBAN STORMWATER RUNOFF, AND RESIDENTIAL USES.

 

ORGANIC CHEMICAL CONTAMINANTS, INCLUDING SYNTHETIC AND VOLATILE ORGANIC CHEMICALS, WHICH ARE BYPRODUCTS OF INDUSTRIAL PROCESSES AND PETROLEUM PRODUCTION AND, CAN ALSO COME FROM GAS STATIONS, URBAN STORMWATER RUNOFF, AND SEPTIC SYSTEMS.

 

RADIOACTIVE CONTAMINANTS ARE NATURALLY OCCURRING.

 

ALL DRINKING WATER, INCLUDING BOTTLED WATER, MAY REASONABLY BE EXPECTED TO CONTAIN AT LEAST SMALL AMOUNTS OF SOME CONTAMINANTS.  THE PRESENT OF CONTAMINANTS DOES NOT NECESSARILY INDICATE THAT THE WATER POSES A HEALTH RISK. MORE INFORMATION ABOUT CONTAMINANTS AND POTENTIAL HEALTH EFFECTS IS AVAILABLE BY CALLING THE ENVIRONMENTAL PROTECTION AGENCY’S (EPA) SAFE DRINKING WATER HOTLINE AT (800) 426-4791.

 

IN ORDER TO ENSURE THAT TAP WATER IS SAFE TO DRINK, EPA PRESCRIBES REGULATIONS THAT LIMIT THE AMOUNT OF CERTAIN CONTAMINANTS IN WATER PROVIDED BY PUBLIC WATER SYSTEMS. WE TREAT OUR WATER ACCORDING TO EPA’S REGULATIONS. FOOD AND DRUG ADMINISTRATION REGULATIONS ESTABLISH LIMITS FOR CONTAMINANTS IN BOTTLED WATER THAT MUST PROVIDE THE SAME PROTECTION FOR PUBLIC HEALTH.

 

SOME PEOPLE MAY BE MORE VULNERABLE TO CONTAMINANTS IN DRINKING WATER THAN THE GENERAL POPULATION. IMMUNO-COMPROMISED PERSONS SUCH AS PERSONS WITH CANCER UNDERGOING CHEMOTHERAPY, PERSONS WHO HAVE UNDERGONE ORGAN TRANSPLANTS, PEOPLE WITH HIV/AIDS OR OTHER IMMUNE SYSTEM DISORDERS, SOME ELDERLY PERSONS, AND INFANTS CAN BE PARTICULARLY AT RISK FROM INFECTIONS. THESE PEOPLE SHOULD SEEK ADVICE FROM THEIR HEALTH CARE PROVIDERS ABOUT DRINKING WATER. EPA/CDC (CENTERS FOR DISEASE CONTROL) GUIDELINES ON APPROPRIATE MEANS TO LESSEN THE RISK OF INFECTION BY CRYPTOSPORIDIUM AND OTHER MICROBIOLOGICAL CONTAMINANTS ARE AVAILABLE FROM THE SAFE DRINKING WATER HOTLINE (800-426-4791).

OTHER SAMPLING EVENTS

 

TOTAL ORGANIC CARBON/UV254:

 

THE DISTRICT USES THIS MONITORING TECHNIQUE AS A MEASURE OF THE EFFECTIVENESS OF OUR TREATMENT PROCESS TO CONTROL THE FORMATION OF DISINFECTION BY-PRODUCTS WHICH ARE REGULATED AND SHOWN IN THIS REPORT.

 

 

SECONDARY CONTAMINANTS:

 

THESE WATER QUALITY PARAMETERS ARE SAMPLED ANNUALLY, AS RECOMMENDED BY THE MASSACHUSETTS DEPARTMENT OF ENVIRONMENTAL PROTECTION, BUT NOT REQUIRED.

 

THE PARAMETERS ARE CONSIDERED A NUISANCE BECAUSE OF AESTHETIC EFFECTS SUCH AS STAINING OF FIXTURES AND LAUNDRY AND DISCOLORATION OF THE WATER SUPPLY.

 

SOME OF THE DISTRICT'S SOURCES HAVE ELEVATED CONCENTRATIONS OF IRON, MANGANESE AND COLOR INTENSITY, WHICH HAS BEEN REMEDIED BY TREATMENT. HOWEVER, ACCUMULATED SOLIDS REMAIN IN THE DISTRIBUTION SYSTEM PIPING WHERE AN EFFORT TO REMOVE THESE SOLIDS CONTINUES WITH THE DISTRICT’S COMPREHENSIVE WATER SYSTEM FLUSHING PROGRAM THROUGHOUT THE YEAR WITH NOTICE PROVIDED THROUGH YARD SIGNS AND OTHER MEDIUMS.

 

CURRENTLY, THE UNITED STATES ENVIRONMENTAL PROTECTION AGENCY HAS ESTABLISHED A LIFETIME HEALTH ADVISORY FOR MANGANESE OF 300 PPB TO PROTECT AGAINST CONCERNS OF POTENTIAL NEUROLOGICAL EFFECTS, AND ONE-DAY AND TEN-DAY HEALTH ADVISORY OF 1000 PPB FOR ACUTE EXPOSURE.

 

 

 

THE DISTRICT’S CONCENTRATIONS IN PPB ARE AS FOLLOWS:

 

MIDWOOD WELLFIELD/MIDWOOD DRIVE    82-399 (SEASONAL USE)    7/22/16 AND 10/27/16

MAKER WELLFIELD/BUSHEE ROAD                                                  28             4/5/16

HORNBINE WELLFIELD/HORNBINE ROAD                                       5               4/5/16

 

 

 

 

SYNTHETIC ORGANIC COMPOUNDS AND OTHER REGULATED OR UNREGULATED COMPOUNDS:

 

A MONITORING WAIVER HAS BEEN ISSUED TO THE DISTRICT FOR SYNTHETIC ORGANIC COMPOUNDS BECAUSE OF THE EFFECTIVENESS OF THE WELLHEAD PROTECTION MEASURES AND RELATED ACTIVITIES.

 

HOWEVER, SAMPLING DATA IS MAINTAINED FOR SYNTHETIC ORGANIC COMPOUNDS AND OTHER REGULATED OR UNREGULATED COMPOUNDS PARTICULARLY THOSE ANALYZED UNDER THE UNREGULATED CONTAMINANT MONITORING RULE, PHASE 3, WHICH TOOK PLACE IN 2015, SO ANY PERSON OR PERSONS WHO IS INTERESTED IN THE RESULTS OF ANY OF THESE ANALYSES IS WELCOME TO VISIT THE WATER DISTRICT OFFICE, DURING REGULAR BUSINESS HOURS, WHERE THIS MATERIAL IS AVAILABLE FOR REVIEW.

 

ABOUT OUR DETECTIONS AND EXCEEDANCES:

 

SODIUM – SODIUM–SENSITIVE INDIVIDUALS, SUCH AS THOSE EXPERIENCING HYPERTENSION, KIDNEY FAILURE, OR CONGESTIVE HEART FAILURE, SHOULD BE AWARE OF THE LEVELS OF SODIUM IN THEIR DRINKING WATER WHERE EXPOSURES ARE BEING CAREFULLY CONTROLLED.

 

VOLATILE ORGANIC COMPOUNDS – THE EPA REQUIRES US TO MONITOR FOR THESE CONTAMINANTS BUT DOES NOT SET LIMITS ON MANY OF THEM.  SOME OF OUR WATER IS PROCESSED THROUGH TREATMENT FACILITIES WHICH ALLOWS THE WATER TO COME INTO CONTACT WITH COATINGS THAT, EVEN THOUGH APPROVED FOR USE FOR POTABLE WATER IMMERSION, DO LEACH THESE COMPOUNDS.

 

LEAD AND COPPER – THE DRINKING WATER SUPPLY THAT THE DISTRICT DERIVES FROM GROUNDWATER IS NATURALLY CORROSIVE TO LEAD AND COPPER PIPING.  TO OVERCOME THIS CONDITION THE DISTRICT ADDS TWO CORROSION CONTROL CHEMICALS (SODIUM HYDROXIDE AND SODIUM CARBONATE) AT EACH OF THE SOURCES OF SUPPLY.

 

ALTHOUGH THE DISTRICT IS COMPLIANT WITH THE LEAD AND COPPER RULE IT IS POSSIBLE THAT SOME HOMES MAY STILL HAVE ELEVATED LEAD LEVELS.

 

“IF PRESENT, ELEVATED LEVELS OF LEAD CAN CAUSE SERIOUS HEALTH PROBLEMS, ESPECIALLY FOR PREGNANT WOMEN AND YOUNG CHILDREN.  LEAD IN DRINKING WATER IS PRIMARILY FROM MATERIALS AND COMPONENTS ASSOCIATED WITH SERVICE LINES AND HOME PLUMBING. SWANSEA WATER DISTRICT IS RESPONSIBLE FOR PROVIDING HIGH QUALITY DRINKING WATER, BUT CANNOT CONTROL THE VARIETY OF MATERIALS USED IN PLUMBING COMPONENTS.  WHEN YOUR WATER HAS BEEN SITTING FOR SEVERAL HOURS, YOU CAN MINIMIZE THE POTENTIAL FOR LEAD EXPOSURE BY FLUSHING YOUR TAP FOR 30 SECONDS TO 2 MINUTES BEFORE USING WATER FOR DRINKING OR COOKING. IF YOU ARE CONCERNED ABOUT LEAD IN YOUR WATER, YOU MAY WISH TO HAVE YOUR WATER TESTED. INFORMATION ON LEAD IN DRINKING WATER, TESTING METHODS, AND STEPS YOUR CAN TAKE TO MINIMIZE EXPOSURE IS AVAILABLE FROM THE SAFE DRINKING WATER HOTLINE OR AT http://www.epa.gov/safewater/lead.”

 

 

 

PERCHLORATE

PERCHLORATE INTERFERES WITH THE NORMAL FUNCTION OF THE THYROID GLAND AND THUS HAS THE POTENTIAL TO AFFECT GROWTH AND DEVELOPMENT, CAUSING BRAIN DAMAGE AND OTHER ADVERSE EFFECTS, PARTICULARLY IN FETUSES AND INFANTS. PREGNANT WOMEN, THE FETUS, INFANTS, CHILDREN UP TO THE AGE OF 12, AND PEOPLE WITH HYPOTHYROID CONDITION ARE PARTICULARLY SUSCEPTIBLE TO PERCHLORATE TOXICITY.

 

TRIHALOMETHANES AND HALOACETIC ACIDS (DISINFECTION BY-PRODUCTS)

THIS YEAR THE DISTRICT EXCEEDED THE MCL, ALSO KNOWN AS THE LOCATIONAL RUNNING ANNUAL AVERAGE, OF 80 PPB FOR TOTAL TRIHALOMETHANES AT THE WATER STORAGE TANK ON SHARPS LOT ROAD WHICH REQUIRED PUBLIC NOTICE.

 

THE DISTRICT HAS TAKEN CORRECTIVE ACTIONS TO RETURN TO COMPLIANCE, HOWEVER, THIS TYPE OF TANK ALLOWS FOR LONG STORAGE TIMES FOR THE WATER HELD IN THE TANK AND MAY REQUIRE A MIXING SYSTEM IF THE PROBLEM IS PERSISTENT.

 

THE MCL IS BASED UPON EXPOSURE OF DRINKING 2 LITERS OF WATER EVERY DAY FOR SEVENTY YEARS SO THE HEALTH RELATED LANGUAGE THAT IS REQUIRED IN THIS REPORT IS THAT SOME PEOPLE WHO DRINK WATER CONTAINING TRIHALOMETHANES AND HALOCETIC ACIDS IN EXCESS OF THE MCL OVER MANY YEARS MAY EXPERIENCE PROBLEMS WITH THEIR LIVER, KIDNEYS, OR CENTRAL NERVOUS SYSTEMS, AND MAY HAVE AN INCREASED RISK OF GETTING CANCER.

 

ABOUT OUR TREATMENT TECHNIQUES:

 

THROUGHOUT THE 2016 YEAR THE DISTRICT OPERATED THREE WATER TREATMENT FACILITIES, AN IRON REMOVAL FACILITY USING A DIATOMACEOUS EARTH PROCESS, A DISSOLVED AIR FLOATATION FACILITY THAT REMOVES IRON, MANGANESE AND ORGANICS INCLUDING COLOR, AND THE DESALINATION FACILITY WHERE CONVERTING SALT WATER TO POTABLE WATER REMOVES ALL PROBLEM CONSTITUENTS.

 

ALL OF THE DISTRICT’S FACILITIES INCLUDING THE GROUNDWATER SOURCES WITHOUT TREATMENT USE SODIUM HYPOCHLORITE (COMMONLY KNOWN AS CHLORINE BLEACH) AS A PRIMARY DISINFECTANT. WITH A DOSAGE OF ONE (1) MILLIGRAM PER LITER (OR PPM) RESULTING IN RESIDUAL CONCENTRATIONS THROUGHOUT THE DISTRIBUTION SYSTEM BEING MUCH LESS.

 

DISINFECTION DOES NOT STERILIZE THE WATER, BUT IT DOES DESTROY HARMFUL ORGANISMS. STERILIZATION KILLS ALL MICROORGANISMS, EVEN THOUGH MOST ARE NOT HARMFUL, AND IS TOO COSTLY TO USE ON A ROUTINE BASIS.

 

CHLORINE DESTROYS ORGANISMS BY PENETRATING CELL WALLS AND REACTING WITH ENZYMES. DISINFECTION WITH CHLORINE HAS BEEN PROVEN EFFECTIVE AT ENSURING THAT WATER IS FREE OF HARMFUL ORGANISMS AND SAFE TO DRINK.

 

ALL CHEMICALS USED IN THE DISTRICT’S WATER TREATMENT PRACTICES HAVE TO MEET PERFORMANCE STANDARDS ESTABLISHED BY THE AMERICAN WATERWORKS ASSOCIATION.

 

THE DISTRICT ADDS FLUORIDE TO THE PUBLIC WATER SUPPLY TO IMPROVE DENTAL HEALTH AND PREVENT TOOTH DECAY. THE ADDITION OF FLUORIDE WAS APPROVED BY VOTE OF THE DISTRICT IN 1968 AND THE PRACTICE OF FLUORIDATION BEGAN IN 1969.

 

FLUORIDE IS A NATURALLY OCCURRING ELEMENT IN MANY WATER SUPPLIES IN TRACE AMOUNTS. IN OUR SYSTEM THE FLUORIDE LEVEL IS ADJUSTED TO AN OPTIMAL LEVEL AVERAGING 0.7 PARTS PER MILLION (PPM OR MG/L) TO IMPROVE ORAL HEALTH IN CHILDREN. AT THIS LEVEL, IT IS SAFE, ODORLESS, COLORLESS, AND TASTELESS.  OUR WATER SYSTEM HAS BEEN PROVIDING THIS TREATMENT SINCE 1969. THERE ARE OVER 3.9 MILLION PEOPLE IN 140 MASSACHUSETTS WATER SYSTEMS AND 184 MILLION PEOPLE IN THE UNITED STATES WHO RECEIVE THE HEALTH AND ECONOMIC BENEFITS OF FLUORIDATION.

 

THE SWANSEA WATER DISTRICT HAS BEEN THE RECIPIENT OF A WATER FLUORIDATION QUALITY AWARD FROM THE UNITED STATES CENTERS FOR DISEASE CONTROL AND PREVENTION FOR THE 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 , 2014 AND 2015 YEARS!

 

ABOUT WATER SUPPLY SECURITY:

 

THE SWANSEA WATER DISTRICT TAKES WATER SUPPLY SECURITY VERY SERIOUSLY AND REQUESTS THAT YOU CALL THE SWANSEA POLICE DEPARTMENT IMMEDIATELY AT 508-674-8464 IF YOU OBSERVE ANY UNUSUAL OR SUSPICIOUS ACTIVITIES ON OR NEAR OUR FACILITIES OR VEHICLES.

 

SOURCE WATER PROTECTION:

 

THE SWANSEA WATER DISTRICT IS ALWAYS DILIGENT IN IDENTIFYING ANY SIGNIFICANT SOURCE OF CONTAMINATION IN THE RECHARGE AREAS OF THE PUBLIC WATER SUPPLY. ADDITIONALLY, A SUMMARY OF THE WATER SYSTEM’S SUSCEPTIBILITY TO POTENTIAL SOURCES OF CONTAMINATION WAS PREPARED BY THE MASSACHUSETTS DEPARTMENT OF ENVIRONMENTAL PROTECTION WHICH IS AVAILABLE FOR REVIEW AT THE DISTRICT OFFICE DURING REGULAR BUSINESS HOURS.

 

LET'S TALK CONSERVATION:

 

THE BOARD OF WATER COMMISSIONERS SUPPORT AND PROMOTE WATER CONSERVATION. IT IS VERY SIMPLE TO REDUCE THE WATER USED IN YOUR HOME OR BUSINESS BY DISPLACING WATER IN THE TOILET TANK, NOT LETTING THE WATER RUN WHEN NOT IN USE OR SIMPLY PURCHASING A WATER SAVINGS KIT, AVAILABLE AT THE DISTRICT OFFICE  AND INSTALLING IT IN YOUR HOME.

 

ADDITIONALLY, STUDIES HAVE SHOWN THAT LAWN WATERING USES NEARLY HALF OF THE WATER AROUND MOST HOMES. MANY OF US TEND TO WATER TOO OFTEN AND LEAVE THE SPRINKLER ON TOO LONG. MOST LAWNS ONLY NEED TO BE WATERED ONCE EVERY THREE DAYS.

 

REMEMBER THAT THE MASSACHUSETTS WATER MANAGEMENT ACT HAS ESTABLISHED SIXTY-FIVE (65) GALLONS PER DAY PER CAPITA AS A PERFORMANCE STANDARD FOR RESIDENTIAL WATER USE THROUGHOUT THE COMMONWEALTH.

 

CROSS-CONNECTION CONTROL:

 

RESIDENTS SHOULD BE AWARE THAT PHYSICAL PIPING CONNECTIONS BETWEEN THE PUBLIC WATER SUPPLY AND ANY OTHER SOURCE OF WATER ARE PROHIBITED EXCEPT IN CASES WHERE A BACKFLOW PREVENTION DEVICE IS ALLOWED BY THE DISTRICT.

 

COMMERCIAL AND INDUSTRIAL USES ARE GOVERNED BY THE MASSACHUSETTS DRINKING WATER REGULATIONS, RESIDENTIAL USES ARE NOT. ALWAYS USE AN AIR GAP TO PREVENT BACKSIPHONAGE WHEN FILLING A POOL, WASHING A CAR OR ANY OTHER ACTIVITY WHERE A HOSE COULD BE LEFT SUBMERGED IN A SOLUTION BECAUSE BACKSIPHONAGE CAN AND WILL OCCUR.

 

ADDITIONALLY, REPORT ANY UNAUTHORIZED USE OF FIRE HYDRANTS, ESPECIALLY WHEN A BACKFLOW PREVENTION DEVICE IS NOT ATTACHED.

 

IF YOU HAVE ANY QUESTIONS ABOUT THIS REPORT OR THE PUBLIC WATER SUPPLY, CALL 508-676-9097 AND ASK FOR ROBERT A. MARQUIS, SUPERINTENDENT.

 

IF YOU WANT TO LEARN MORE ABOUT THE SWANSEA WATER DISTRICT IN GENERAL, YOU ARE WELCOME TO ATTEND ANY OF OUR REGULARLY SCHEDULED MEETINGS. THE DISTRICT’S BOARD OF WATER COMMISSIONERS MEETINGS ARE OPEN TO THE PUBLIC AND ARE HELD ON THE SECOND AND FOURTH MONDAY OF EACH MONTH IN THE DISTRICT’S BOARDROOM LOCATED AT 700 WILBUR AVENUE.

 

2017 WATER USE INFORMATION

 

THE MASSACHUSETTS WATER MANAGEMENT ACT REQUIRES THE DISTRICT TO PLACE SEASONAL LIMITS ON NON-ESSENTIAL OUTDOOR WATER USE BY A CALENDAR TRIGGER BETWEEN MAY 1ST AND SEPTEMBER 30TH OR BY A STREAMFLOW TRIGGER.

 

THE DISTRICT HAS SELECTED STREAMFLOW TRIGGERED RESTRICTIONS BASED UPON A UNITED STATES GEOLOGICAL SERVICE GAUGING STATION IN EAST PROVIDENCE, RHODE ISLAND AND SHALL ADVISE THE SERVICE POPULATION WHEN NO NON-ESSENTIAL OUTDOOR USE SHALL TAKE PLACE FROM 9 AM TO 5 PM.

 

TOGETHER, WE CONTINUE TO DO GOOD THINGS FOR SWANSEA!
