| The Branch of Quality Systems (BQS) operates an Organic Blind Sample Project (OBSP).
One of the goals of the project is to document bias and variability for the National
Water Quality Laboratory (NWQL) through the use of blind quality assurance (QA) samples. From these summaries, data users can be informed of the NWQL's performance on QA
samples that parallel their own environmental samples.
All data is provisional and may change if the OBSP deems necessary. A red analyte name is an indication of a permanently estimated compound . |
