Water-Quality Assessment of the Sacramento River
Basin, California: Water-Quality, Sediment and Tissue
Chemistry, and Biological Data, 1995-1998
(Open-File Report 2000-391)

Quality Control
Spiked sample data: Ground Water

Pesticides in filtered water (0.7 micrometer glass fiber filter)
analyzed by gas chromatography/mass spectrometry

Number of significant figures do not reflect analytical method
reporting levels.

[Cannot Calculate - Recovery of pesticide cannot be calculated because of estimated analytical values]
