CONSUMER CONFIDENCE REPORT <br />PWSID: 1020035 <br />AL—Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other requirement <br />which a water system must follow. <br />90th Percentile Level—This is the value obtained after disregarding 10 percent of the samples taken that had the highest <br />levels. (For example, in a situation in which 10 samples were taken, the 90th percentile level is determined by <br />disregarding the highest result, which represents 10 percent of the samples.) Note: In situations in which only 5 <br />samples are taken, the average of the two with the highest levels is taken to determine the 90th percentile level. <br />pCi/I—PicoCuries per liter (a measure of radioactivity). <br />ppm—Parts per million, which can also be expressed as milligrams per liter (mg/I). <br />ppb—Parts per billion, which can also be expressed as micrograms per liter (µg/1). <br />nd—No Detection. <br />N/A—Not Applicable (does not apply). <br />Contaminant <br />(units) <br />MCLG <br />MCL <br />Level Found <br />Typical Source of Contaminant <br />Range <br />(2014) <br />Average/ <br />Result* <br />Alpha Emitters <br />(pCi/l) <br />0 <br />15.4 <br />nd-5.7 <br />5.7 <br />Erosion of natural deposits. <br />Barium (ppm) <br />2 <br />2 <br />N/A <br />.1 <br />Discharge of drilling wastes; Discharge from metal <br />refineries; Erosion of natural deposits. <br />Combined Radium <br />(pCi/l) <br />0 <br />5.4 <br />nd-1.3 <br />1.3 <br />Erosion of natural deposits. <br />Fluoride (ppm) <br />4 <br />4 <br />.72-1.3 <br />1.11 <br />State of Minnesota requires all municipal water <br />systems to add fluoride to the drinking water to <br />promote strong teeth; Erosion of natural <br />deposits; Discharge from fertilizer and aluminum <br />factories. <br />Haloacetic Acids <br />(HAAS) (ppb) <br />0 <br />60 <br />N/A <br />1.2 <br />By-product of drinking water disinfection. <br />TTHM (Total <br />trihalomethanes) <br />(ppb) <br />0 <br />80 <br />1.8-1.9 <br />1.9 <br />By-product of drinking water disinfection. <br />2 <br />
