SOP for Surface Water Sampling — Hansen Project 6
3.7 Flow Rate
After collecting surface water samples, the surface water flow rate will be measured to ascertain the surface
water flow conditions at the time of sample collection. The surface water flow rate should be measured and
recorded according to the procedures described in the SOPs for Stream Flow Measurement (Appendix D).
4. SAMPLE HANDLING
Sample containers and preservatives are specified in the QAPP and in the Baseline Hydrologic Monitoring
Plan. All samples will be labeled and handled as described in the QAPP. The analytical suite is specified in
the Baseline Hydrologic Monitoring Plan.
5. DOCUMENTATION
5.1 Field Sampling Data
The following field sampling data will be collected at each sample location. A blank field sampling data sheet
is attached with this SOP. Items not applicable to the sampling will be labeled as not applicable (NA). The
data includes the following:
• Sampling location
• Date and time of sampling
• Person performing sampling
• DO, conductivity, temperature, pH, and ORP results
• Color (describe), odor (describe), turbidity (Y/N or visual estimate of cloudiness)
• Sample ID number
• Number of samples taken
• Preservation of samples
• Record of any QA/QC samples from site
• Any irregularities or problems which may have a bearing on sampling quality.
5.2 Field Notes
Field notes will also be kept during sampling activity. The following information will be recorded in the bound
fieldbook using waterproof ink:
• Names of personnel
• Weather conditions
• Date and time of sampling
• Location and sample station number
• Sketches of channel geometry or sample location, as appropriate
• Stream characteristics, flow, post - storm, snow melt present, physical objects that may affect
Water quality, flow
• Times that procedures and measurements are completed
• Decontamination times
• Calibration information
• Calculations
6. DISCUSSION
The overall objective of the surface water baseline monitoring program is to obtain samples which accurately
depict the chemical water quality at each station. Surface water samples should be collected prior to flow
measurement, to avoid channel bottom disturbance and collect the most representative sample. Where multiple
