Project: Well Number: in Tracy, CA M LJ is Job #/Description: Prepared By: Purging/Sampling 2 & 4" Monitoring Well ©ate. QED MP-SP Bladder Pump BRU 3 / 17 / 2-3 Micro-Purge Sampling Log Sampling Protocol: Flow rate must be within 200 to 300 milliliters per minute. Flow rate must be steady while maintaining a DTW drawdown of less than 0.33 feet. A minimum of one system volume (VS) must be purged prior to recording the water-quality indicator parameters if using a dedicated pump. Monitor and record parameters every three to five minutes. Stabilization for 3 consecutive measurements of pH, conductivity, ORP, DO, and turbidity is required before sampling. Do not sample from flow-through cell.
