About this file
This is a system monitoring form for the Valley Park TCE Site Groundwater Extraction System, documenting inspection procedures and operational parameters for a contaminated groundwater remediation facility. The form captures real-time operational data for the extraction well, antiscalant metering system, sediment bag filters, and air stripper blower components. Inspections are conducted to verify that system components operate within established ranges, including flow rates (178-182 gpm), extraction well water levels (35-50 feet below top of casing), pressure gauges (8-15 psi), and air stripper pressure (35-42 inches of water). The form includes checkpoints for routine monthly maintenance tasks such as antiscalant level verification, air stripper tray inspection and drainage, Fernco fitting adjustments, and monitoring well gauging at designated locations (MW-55 and MW-56). System status is documented both upon arrival and departure, with operators required to record all readings, verify control panel illumination patterns, and confirm proper switch positions on automated equipment.
The monitoring form establishes operational setpoints and control parameters managed through SiteLink Controls, including water level controls, dosing pump setpoints at manual (50 percent) and automatic (200 gpm) modes, and variable frequency drive settings (37-42 Hz). Runtime hours are tracked for the SVE and fan systems, ASP-10 blower, P-10 well pump, and DP-VLS pump to monitor equipment utilization and maintenance schedules. The form includes verification checkboxes requiring operators to confirm that all indicator lights and switch positions match required configurations, with notation space for any deviations or issues encountered. This standardized inspection document was revised on March 13, 2020, and serves as both an operational record and compliance documentation for ongoing groundwater remediation activities at the site.
