Page 1 of 2 LOW-FLOW GROUNDWATER SAMPLING PROTOCOLS A static water level measurement will be taken prior to commencing any purging and sampling activities. The groundwater level will be measured using an electric water level indicator. The depth to water will be measured from a datum marked on the rim of the riser pipe to an accuracy of +0.01 feet. The static water level measurements will be recorded in the field logbook. A micro-purge low-flow method will be used for well purging prior to sampling. This method is used to provide for representative samples while minimizing purge water and minimizing disturbance of sediment in the well that may be caused by over-pumping. The procedure to be used is as follows: • Prevent decontaminated equipment from contacting the ground surface by using new plastic sheeting or by placing tubing/pumps in clean storage tubs. • Slowly lower the decontaminated pump into the well until the pump intake is in the middle of the screen interval. Measurement of the water level in the well is needed prior to well purging. The pump tubing will be clearly marked with depth increments to facilitate accurate determinations of pump depth. • Secure the tubing to the wellhead when the pump is at the desired depth. • The dedicated polyethylene lined tubing will be secured so purging will take place from the approximate midpoint of the monitoring well screen. • Turn pump on and slowly increase to a flow rate of 100 ml to 500 ml per minute, and discharge directly into bucket until turbidity has decreased. Check water level periodically to monitor drawdown in the well as a guide to flow rate adjustment. The goal is minimal drawdown (
Page 2 of 2 Purging will be performed at a rate to minimize drawdown and to minimize the risk of the well going dry during purging. If the well does go dry during purging, samples will be collected after sufficient groundwater enters the well. Upon stabilization of field parameters during well purging, samples will be collected directly from the pump discharge. Samples will be collected in order of decreasing volatility: such that if analyses include VOCs, then a sample will be collected first for VOCs analysis (containers include preservatives). Field quality assurance/quality control (QA/QC) samples (equipment blanks, trip blanks, and field duplicates) will be collected at the frequency specified in the Field Quality Control Samples SOP or as otherwise specified. The samples will be collected in appropriate laboratory supplied containers, preservative added depending on the analysis, cooled to 4°C, packed and hand delivered to the analytical laboratory. All containers will be furnished by the analytical laboratory according to US EPA protocols. \\ilch-itfs01\V3il_Chi\ADMIN\STD OPERATING PROCEDURES\SOPs Source Docs\5.0 Data Gen and Acq\5.1 Field SOPs\Protocols\Groundwater Well Installation & Sampling\Low-flow GW Sampling Protocol.doc
