Indicate the sample time,total purge volume and water level reading as the last row of parameter readings. <br /> f# <br /> Note:The final row of readings should list the time sampling was completed and an estimate of the total volume of water removed. Water measurements should be recorded at each well easing <br /> volume. In the.,Qbservati"s field,note which reading applies to the values recorded at sampling. <br /> r — <br />
