Most Current Recovery vs Concentration Charts for NWQL LS 4437

The recovery versus concentration charts provide OBSP recovery information for every analyte at different concentrations for every schedule OBSP assesses.

The black line on the chart describes the median recovery of the data.

The charts and data that you might secure from this U.S. Geological Survey (USGS) web page (identified as "OBSP") have not received official USGS approval and as such are provisional and subject to revision. The charts and data are released on the condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from its authorized or unauthorized use.
