I� <br /> L <br /> replacement for the South Tracy#I well. Further, since 2006, the Granite#3 well replaces the Brown's <br /> L <br /> #I well for water quality monitoring purposes, as the Brown's#I well was vandalized in 2005. Lastly, <br /> from 1994 to 1997,the Koster irrigation well was sampled periodically(depending on the availability of a <br /> tractor engine for the pump). <br /> Samples from the water quality network wells are analyzed for electrical conductivity(EC),total <br /> dissolved solids(TDS), pH, general minerals(calcium, magnesium, sodium,potassium, sulfate, chloride, <br /> total alkalinity [including hydroxide,carbonate, and bicarbonate alkalinity], and total hardness), nitrate, <br /> L nitrite, fluoride, boron, and metals [copper, iron, manganese, and zinc]). Samples from the Hall and <br /> Faulkner domestic wells are also analyzed for coliform bacteria(SM 9221 B [I 5-tube] procedure with <br /> fecal confirmation). Phosphorus sampling was discontinued in 1998. <br /> LTeichert's ongoing monitoring and reporting activities are inclusive of(and exceed)activities specified in <br /> Granite's approved Groundwater Monitoring Plan(LSCE, 2009). Specifically, Granite's approved <br /> Groundwater Monitoring Plan stipulates: <br /> L1. Semi-annual groundwater level measurements in five shallow wells(Hall,Rustan,Thoming, <br /> Koster, 4S/6E-5A1), one composite well (Pett),and four deep wells(South Tracy#3,Granite <br /> L #4, Brown's#1, Brown's New). <br /> 2. Semi-annual groundwater quality retrieval from one shallow well(Hall)and three deep wells <br /> (South Tracy#3, Granite#3, and Brown's New). Groundwater quality laboratory analyses shall <br /> consist of the same constituents listed above for Teichert's compliance monitoring activities <br /> l minus nitrite, fluoride,total hardness, and bacteriological analyses. <br /> v <br /> 7 <br /> v <br /> v <br /> k <br /> 4 <br /> tr <br /> ©LLJ-K p FF b SCALNIANIP41 <br /> CONSULTING ENGINEERS <br />
