The laboratory will be notified they will be responsible for filtering dissolved <br /> samples prior to placing a bottle order. <br /> 3.2.4.2 Static Water Levels <br /> Static water levels in the wells will be measured and recorded using a water level well <br /> sounder prior to any pumping of the well. The measurement location at the top edge <br /> of the casing will be marked with permanent ink pen and should be touched up with <br /> fresh ink at each sampling event. <br /> 3.2.4.3 Purging <br /> Monitoring wells will be purged prior to sample collection. Either a low-flow submersible <br /> pump or polyurethane bailers will be used to purge the wells and collect samples, <br /> depending on the required purge volume. Pumps will be decontaminated prior to being <br /> placed in each well, whereas new bailers will be used and disposed of for each well. <br /> Removal of three well casing volumes will occur prior to sampling. The static volume <br /> of water in the well will be calculated using the following equation: <br /> V = r2h(0.163) <br /> Where <br /> V = static volume of water in well (in gallons) <br /> r = inner radius of well casing (in inches) <br /> h = length of water column (in feet) which is equal to the <br /> total well depth minus depth to water. <br /> 0.163 = a constant conversion factor that compensates <br /> 12 <br />
