Sampling And <br /> Analytical'Protocol <br /> The following protocols have been developed to increase the accuracy and comparability <br /> groundwater monitoring data. The purposes of establishing and following.the fied protocols <br /> the <br /> {I) to reduce sources of error that can be introduced duringP ols are <br /> �P�g and, (2) t® collect samples <br /> in a consistent manner so that data sets are'con le. Therefore, project goals for <br /> comparability and include followuig the Procedures described in this <br /> recti®n to the <br /> Cdent_possible. When field conditions necessitate a change from the established <br /> n chin protocols, the <br /> ger be implemented with maintenance of sampling :accuracy and daia set <br /> ,comparability as priorities. Any modification to the standard procedures delineated. <br /> tkts <br /> protocol necessitated by field conditions and the reasons gill be noted on the in <br /> Report(See Section 2.7).. Technicians Daily <br /> Depth To Water Measurements <br /> Depth to water mets will be made in all'the wells at the site prior to initiating <br /> and�P�g, including.wells that.are not to be sampled. .ZTxe Purgong <br /> P moments will be made four <br /> tunes a Year prior to initiating each sampling round. There are no p1=0mGt=Mt the site. The <br /> depth to water Measurements will be made consecutively,iris short a time as possible, to reduce.: �,) <br /> potential errors due to daily variations in the water table. <br /> -to-water (DTVI) will be m _in the well to within 1/100 of a foot using a <br /> conductivity-based water level indicator.' Measurements will be taken from the north ormarked <br /> side of the top of casing of each well. These mmia on die <br /> casings, have been surveyed by a <br /> 'eY rehaOe to mean.sea level ). In wells with dedicated pumps,the water level <br /> probe is inserted into the well through a hole in the well <br /> cable cap. The conductivity probe and <br /> will be <br /> in dein before and after mmiutibg the first well, and after each <br /> subsequent well. The same water level indicator will be used in each well. Depth to water <br /> MeasureM=t will be recorded on a field obsavation.sheet <br /> Monitoring Well Purging Prior To Sampling <br /> Groundwater-samples will ba collected from existingmonitoring wells at Forvrard LandfillAACr <br /> g the water ` gin <br /> o the well.
