SOP No. 22.0 Purging and Sampling Monitoring Well <br />7. To determine the number of gallons required to purge the well, multiply the number of <br />gallons in one well volume (calculations above) by three. Record the minimum purge <br />volume in the field log book. <br />8. Purge the well using either a clean disposable bailer or a decontaminated pump (see <br />below for equipment-specific instructions). <br />9. Affix a sample label to each sample container and complete all required information <br />(sample no., date, time, sampler's initials, analysis, preservatives). Place clear tape over <br />label. Record sample number, well number, date, time, and the sampler's initials in the <br />field book. <br />10. Collect the groundwater samples after purging is complete. <br />11. Complete chain-of-custody forms with appropriate sampling information. <br />12. Complete both front and back of the groundwater monitoring data log (attachment) for <br />each monitoring well or sampling point upon return from the field, using data from the <br />field book. <br />Purim with a Bailer <br />1. Ensure that fine sediment has been removed by well development. <br />2. Determine the volume of water in well casing. <br />3. Tie a slip knot around the neck of the Teflon bailer. This should be done with clean <br />sample gloves. <br />4. Release the bailer down into the well until the bailer is completely submerged below the <br />water surface. Loop free end of bailer rope around wrist to prevent bailer loss down well. <br />5. When the bailer is full, retrieve it from the well. Do not allow bailer or bailer rope to <br />come into contact with the ground surface. Place plastic sheeting around the well if <br />necessary. <br />6. Measure water quality parameters after the first well volume has been removed (see SOP <br />"Field Parameter Measurements"). Record water color, smell, suspended particulates, <br />discoloration of casing, casing diameter and material, any unusual occurrences during <br />sampling, and any pertinent weather details in the field log book. <br />7. Bail the well at a uniform rate, measuring water quality parameters after the collection of <br />each original casing volume. <br />8. Dispose of the contents of the bailer in an appropriate container for later disposal in <br />compliance with federal and state laws. <br />9. Attempt to remove a minimum of three well volumes before sampling. <br />a. If unable to remove 3 well volumes, purge until well is dry, or as nearly dry as <br />possible. <br />b. Measure the field parameters again as soon as enough water has returned to measure. <br />c. Bail the well down again when it has recovered at least one half of the original casing <br />volume. <br />4/23/07 Page 3 of 7 R Squared Inc. <br />Attachment A
