COLLECTION OF GROUNDWATER SAMPLES. Groundwater samples will be collected using low-flow techniques in accordance with U.S. EPA guidance (EPA/540/S-95/504, April 1996). The following general procedures will be followed during groundwater sampling events. • For monitor xxxxx with a depth to water measurement of less than 20 feet below ground surface (bgs), disposable polyethelene tubing will be inserted into the well to a depth where the tubing intake is at the approximate midpoint of the screened interval. The tubing will then be attached to a non-submersible peristaltic pump for purging and sampling; • Xxxxx with depth to water measurements greater than 20 feet below ground surface will be sampled with either a dedicated QED bladder pump or a deconned stainless-steel Monsoon pump. Both of these options are equipped with polyethene tubing and are either set at the midpoint of the screened interval or inserted, depending on pump type used; • All purging will be at a set flow rate generally less than 0.5 L/min (within a range of 0.1 L/min to 0.5 L/min); • The desired drawdown created by the purging process is less than the U.S. EPA recommended 0.1 meter (0.33 feet). In instances where drawdown exceeds 0.1 meter (0.33 feet), a purge rate of less than 0.5 L/min will be maintained; and • Water quality indicator parameters, such as pH, temperature, conductivity, dissolved oxygen, oxidation reduction potential and turbidity will be collected using an In-Situ Aqua Troll 600 (or equivalent) water quality meter. The Aqua Troll utilizes the Vu Situ Android application where all water quality parameters are monitored and user is notified when all parameters are stable. When all parameters are stabilized or after 45 minutes of purging, whichever occurs first, a sample will be collected. Sampling personnel will record all measurements in a field logbook immediately after collection. Low flow purging reports are generated by the Vu Situ application and can be printed for reporting purposes. Ground water samples will be collected immediately after low-flow sampling and parameter stabilization occurs using the appropriate pump and tubing. The submersible pump will be decontaminated between each well using liquinox and plant potable water. A final distilled water rinse will also be conducted. Purge water and decontamination water will be placed in plastic 30 drum or 20-liter carboys and discarded in the plant’s wastewater treatment system. If the wastewater treatment system is not available, purge and deconta...
