Baseline Hydrologic Monitoring Plan — Hansen Project 27
3.2 Monitoring Frequency and Duration
Six surface water stations near the Hansen portion of the Project are monitored quarterly for water quality
and flow rates, while the six stations the northern portion of the Project are monitored annually (Table 6).
The quarterly and annual periods are shown in Table 8.
Table 8. Surface Water Monitoring Frequency
3.3 Surface Water Monitoring Procedures
Sample collection, sample handling, laboratory analysis, and field data collection are conducted in
accordance with strict environmental protocols for water quality sampling. Standard Operating Procedures
(SOPS) for baseline water quality monitoring have been developed in accordance with best practices for
ensuring precision, accuracy, reliability, and repeatability of the data collected. Appendix A provides SOPs
for calibration of field instruments. Appendix B provides procedures for equipment decontamination.
Samples will be collected in decontaminated 1 -liter bottles using a swing - sampler and extendable fiberglass
pole. Samples will be collected from the midpoint of the stream, and manually depth- integrated to obtain a
sample that is considered representative of the entire creek at that location. Standard Operating Procedures
and forms for surface water monitoring are provided in Appendix C.
Samples for dissolved metals and TDS are field - filtered through a 0.45 µm filter using a peristaltic pump
and dedicated (disposable) tubing. Samples are stored on ice for shipment to ACZ Laboratories (ACZ) of
Steamboat Springs, Colorado, a NELAC - certified analytical lab, via express carrier.
Surface water samples are also collected for QA /QC purposes, as outline in the Quality Assurance Project
Plan (QAPP) (Appendix G). For each sampling round (winter, spring, summer, and fall), one blind
duplicate surface water sample is collected. Duplicate QC evaluation procedures are described in the
QAPP.
3.4 Analytical Suite
Surface water is analyzed for field parameters (Section 3.4. 1) and laboratory parameters (Section 3.4.2).
The surface water analytical suites were developed based on Colorado instream water quality standards for
the specified reaches, Colorado Basic Standards for surface water, EPA drinking water standards, and
