| The National Field Quality Assurance Program (NFQA) was created in 1979 to provide quality-assurance reference samples to field personnel who make water quality field measurements. The program monitors the proficiency of alkalinity, pH, and specific conductance measurements determined by water quality field analysts. Nationwide, hundreds of field measurements are made daily by USGS field-analysts. The data reported by the NFQA program provides a confidence level to these field measurements by testing the proficiency of the instruments and the field-analyst to measure prepared test samples. The proficiency data obtained through the NFQA should be reflected in the data collected by the field-analyst on a daily basis. The data produced by the NFQA program also documents the precision of the method for alkalinity, pH, and specific conductance. |
