About this file
This is a groundwater extraction system monitoring form for the Valley Park TCE (trichloroethylene) Site, used by the responsible environmental agency or contractor to document operational status and performance metrics during routine inspections and maintenance visits. The form captures physical component readings, system status upon arrival and departure, and operational parameters for the extraction well, antiscalant metering system, sediment bag filters, and air stripper blower. Key monitored components include the E+H flow meter (178-182 gpm typical operating range), extraction well water level (35-50 feet below top of casing), pump pressure (8-15 psi), antiscalant metering rate (~0.03 gal/day), bag filter pressure differentials across multiple stages (3-9 psi pre-filter to 2.5-7 psi post-filter), and air stripper pressure (35-42 inches of water). The form includes both daily inspection checkpoints and monthly maintenance tasks such as antiscalant level verification, air stripper tray inspection, drain procedures, and monitoring well gauging for wells MW-55 and MW-56.
The form integrates data from the SiteLink Controls remote monitoring system (https://sitelink.newterra.com/), which tracks flow meter readings, water level control setpoints, dosing pump settings, and equipment runtimes for the blower and extraction well pump. Standard operational setpoints include water level control at 58 feet below top of casing (LC-10), pump activation at 50 feet, and automatic dosing pump settings at 200 gpm. The monitoring protocol requires documentation of system verification checkpoints, such as confirming that ASP-10 blower and VFD pump status lights are properly illuminated and switch positions are set to specified configurations (AUTO, OFF, OFF, OFF, AUTO). This systematic inspection and data collection process supports ongoing groundwater remediation operations and ensures the extraction system maintains optimal performance within established operational parameters.
