About this file
This is a system monitoring form for the Valley Park TCE Site Groundwater Extraction System, a remediation operation focused on managing contaminated groundwater. The form provides a standardized inspection checklist and data collection template for personnel conducting routine monitoring and maintenance of the extraction and treatment system. Key components monitored include extraction well operations, flow rates, water levels, antiscalant metering systems, sediment bag filters, air stripper performance, and variable frequency drive (VFD) settings. The form tracks physical component readings against typical operating ranges, such as extraction well flow rates of 178 to 182 gpm, water level depths of 35 to 50 feet below top of casing, and air stripper pressure readings of 35 to 42 inches of water. Site personnel are required to conduct daily system status checks and monthly maintenance tasks including antiscalant level verification, air stripper tray inspections, monitoring well gauging at locations MW-55 and MW-56, and equipment runtime documentation through the SiteLink Controls remote monitoring system.
The form establishes specific setpoints and control parameters for automated operation, including pump on levels at 50 feet below top of casing, dosing pump settings at 50 percent manual setpoint with 200 gpm automatic setpoint, and VFD frequency commands between 37 to 42 Hz. Inspectors must verify that appropriate indicator lights are illuminated and switch positions are set to designated AUTO/OFF configurations to ensure proper system function. The document was last revised on March 13, 2020, and serves as the operational record for ongoing groundwater remediation activities at this contaminated site, supporting both compliance documentation and system optimization through continuous performance monitoring.
