Any physical, chemical or biological condition that threatens the designated ...

  • Quality assurance and quality control technical note

    The primary activities taken to assure and control data quality are aptly called quality assurance and quality control. Determining the “true value” of a water quality measurement is an important fundamental of any QA/QC program. To determine the true value, many professionals apply a second means of measuring the parameter of interest, such as another instrument that is kept serviced ...

  • Lag time in water quality response to best management practices: a review

    Received for publication March 20, 2009. Nonpoint source (NPS) watershed projects often fail to meet expectations for water quality improvement because of lag time, the time elapsed between adoption of management changes and the detection of measurable improvement in water quality in the target water body. Even when management changes are well-designed and fully implemented, water quality ...

  • Water quality monitoring with hydrolab MS5
