About this file
This is a system monitoring and inspection form for the Valley Park TCE Site Groundwater Extraction System, a remediation facility addressing trichloroethene (TCE) contamination. The form documents operational status, physical component readings, and maintenance activities required at regular intervals. The monitoring checklist captures data on extraction well performance, antiscalant metering systems, sediment bag filters, air stripper equipment, and variable frequency drive (VFD) settings. Inspectors record system status upon arrival and departure, measure flow rates (target range 178-182 gpm), water levels, pressure readings across multiple components, and antiscalant inventory. Monthly maintenance tasks include checking antiscalant levels, inspecting outfall conditions, maintaining air stripper trays, and gauging monitoring wells MW-55 and MW-56. The form also requires verification of control panel indicator lights and switch positions to ensure proper operational configuration.
The document includes specific operating ranges and setpoints for all monitored components, including extraction well pressure (8-15 psi), air stripper pressure (35-42 in H2O), and water level thresholds (50-58 feet below top of casing). Personnel conducting inspections must document readings through the SiteLink Controls online platform and verify that automated systems are functioning correctly. This monitoring form, last revised March 13, 2020, serves as the primary documentation tool for ongoing operational oversight and regulatory compliance at this groundwater remediation site, ensuring consistent performance of extraction, treatment, and air stripping systems.
