TABLE 1. GROUNDWATER SAMPLING ANALYTE LIST6
An independent, certified laboratory will analyze the groundwater samples. The analytical
results will be returned to NS for review and compilation. If any given water quality
parameter is deemed to have a reading which differs from historical baseline data, NS may
require the laboratory to re -analyze the parameter in question. If subsequent testing in the
well indicates additional elevated readings for the same parameter, NS will notify the BLM
of the situation. If the anomaly appears to be significant, the regional historical water -
quality data from Solvay, Shell E&P, C -b Tract, C -a Tract, WPX, and USGS may be utilized to
determine the significance of the anomaly. In addition, the data may be used to determine
whether additional sampling frequency and analyses are required. Water quality sampling
will focus on the affected aquifer at the nearest down -gradient monitoring well. Weekly
manual water levels may be obtained for wells sampled for water quality. One or all of the
regulatory agencies—BLM, DRMS, and EPA—will be consulted to develop site-specific
