Quality assurance and quality control are fundamental to data integrity, yet adequate controls are often not in place to meet the sampling objectives. RiverMetrics™ can develop Standard Operating Procedures for instrumentation and sampling methods, and the company can visit field sites and sediment laboratories to determine if QA&QC methods are in place, and if they are satisfactory.
