2014 Water Quality Report for Harbor Beach Water Treatment Plant

Transcription

1 This reprt cvers the drinking water quality fr the Harbr Beach Water Treatment Plant fr the calendar year This infrmatin is a snapsht f the quality f the water prvided t yu in Included are details abut where the water cmes frm, what it cntains, and hw it cmpares t EPA and State standards. The Harbr Beach Water Treatment Plant (HBWTP) btains water frm Lake Hurn, ne f the quality surces f fresh water in the wrld. The State perfrmed an assessment in f ur surce water in The surce water area fr the Harbr Beach intake includes 17 ptential cntaminant surces. These cntaminant surces, cmbined with the highly sensitive intake leads t a highly susceptible determinatin fr the Harbr Beach water supply intake. The final assessment reprt is available fr review at the water plant. Cntaminants and their presence in water: Drinking water, including bttled water, may reasnably be expected t cntain at least small amunts f cntaminants. The presence f cntaminants des nt necessarily indicate that water pses a health risk. Mre infrmatin abut cntaminants and ptential health effects can be btained by calling the EPA s Safe Drinking Water Htline ( ) Vulnerability f sub-ppulatins: Sme peple may be mre vulnerable t cntaminants in drinking water than the general ppulatin. Immun-cmprmised persns such as persns wh have undergne rgan transplants, underging chemtherapy, peple with HIV/AIDS r ther immune system disrders, sme elderly, and infants can be particularly at risk frm infectins. These peple shuld seek advice abut drinking water frm their health care prviders. EPA/CDC guidelines n apprpriate means t lessen the risk f infectin by Cryptspridium and ther micrbial cntaminants are available frm the Safe Drinking Water Htline. Surces f Drinking Water: The surces f drinking water (Bth tap water and bttled water) include rivers, lakes, streams, pnds, reservirs, springs, and wells. As previusly stated, ur water cmes frm Lake Hurn. As water travels ver the surface f the land r thrugh the grund, it disslves naturally ccurring minerals, and in sme cases radiactive material, and can pick up substances resulting frm the presence f animals r humans. Cntaminants that may be present in surce water include: Micrbial: such as viruses and bacteria, which may cme frm sewage treatment plants, septic systems, agricultural livestck peratins, and wildlife Inrganic: such as salts and metals, which can be naturally ccurring r result frm urban strm runff, industrial r dmestic wastewater discharges, il and gas prductin, mining and farming Pesticides and herbicides: which may cme frm a variety f surces such as agriculture and residential use Radiactive: which can be naturally ccurring r be the result f il and gas prductin and mining activities Organic chemicals: including synthetic and vlatile rganic chemicals, which are by-prducts f industrial prcesses and petrleum prductin, and can cme frm gas statin, urban strm water runff, septic systems In rder t ensure that tap water is safe t drink, EPA prescribes regulatins that limit the amunt f certain cntaminants in water prvided by public water systems. FDA regulatins establish limits fr cntaminants in bttled water which prvide the same prtectin fr public health.

2 The table belw lists all the drinking water cntaminants that we detected during the 2014 calendar year. The presence f these cntaminants in the water des nt necessarily indicate that the water pses a health risk. Unless therwise nted, the data presented in this table is frm testing dne January 1 December 31, The State allws us t mnitr fr certain cntaminants less than nce per year because the cncentratins f these cntaminants are nt expected t vary significantly frm year t year. All f the data is representative f the water quality, but sme may be mre than ne year ld. Terms and abbreviatins used belw: Maximum Cntaminant Level Gal (MCLG): The level f a cntaminant in drinking water belw which there is n knwn r expected risk t health. MCLGs allw fr a margin f safety Maximum Cntaminant Level (MCL): The level f a cntaminant that is allwed in drinking water. MCLs are set as clse t MCGLs as feasible using the best available treatment technlgy Maximum Residual Disinfectant Level (MRDL): The level f disinfectant allwed in drinking water. There is cnvincing evidence that additin f a disinfectant is necessary fr cntrl f micrbial cntaminatin. Maximum Residual Disinfectant Level Gal (MRDLG): The level f drinking water disinfectant belw which there is n knwn r expected risk t health. MRDLGs d nt reflect the benefits f the use f disinfectants t cntrl micrbial cntaminants N/A: Nt Applicable ND: Nt Detectable at testing limit ppb: parts per billin ppm: parts per millin r milligrams per liter pci/l: piccuries per liter (measure f radiactivity) Actin Level (AL): The cncentratin f a cntaminant which, if exceeded, triggers treatment r ther requirements that a water system must fllw Treatment Techniques (TT): A treatment technique is a required prcess intended t reduce the level f a cntaminant in drinking water Nephelmetric Turbidity Unit (NTU): nephelmetric turbidity unit is a measure f the clarity f water.

Lead in drinking water is primarily frm materials and cmpnents assciated with service lines and hme plumbing. The Harbr Beach Water Treatment Plant is respnsible fr prviding high quality drinking water, but cannt cntrl the variety f materials used in plumbing cmpnents. When yur water has been sitting fr several hurs, yu can minimize the ptential fr lead expsure by flushing yur tap fr 30 secnds t 2 minutes befre using water fr drinking r cking. If yu are cncerned abut lead in yur water, yu may wish t have yur water tested.
