Attachment_2_-_Well_Parameters.pdf

This document is a technical specification table defining well parameters to be recorded in NPS reports and Wyoming Department of Environmental Quality (WYDEQ) GEM reports for monitoring well activities.

The table specifies 20 parameters that must be monitored across various well locations including LM, BC, GV, Moose, SJL, Moran, and AMK Ranch wells. Parameters are categorized into three types: basic well information (date, time, casing elevation, depth of well), water quality measurements (pH, specific conductance, air and water temperature), and chemical/biological analyses (ammonia, nitrate, chloride, phosphorus, total coliform, E. coli, and formaldehyde). For each parameter, the table identifies which monitor wells require testing, specifies the applicable analytical method (such as EPA 150.1, EPA 350.1, NIOSH 3500 Mod.), and establishes permit limits or upper control limits (UCL). Notable permit limits include pH of 6.5-8.5, ammonia as N at 0.50 mg/l, nitrate as N at 10.0 mg/l, chloride at 250 mg/l, total coliform at 1/100 ml, and formaldehyde at 7.29 mg/l. Several parameters including elevation of static water, top of casing elevation, and height of casing above ground surface are to be provided by NPS rather than newly measured.
