Ground water blank frequency table

This table describes the frequency and laboratory schedules for
quality-control blank samples collected at ground water sites.

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

[X indicates sample was collected, 2751 - major inorganic constituents, 2752 - nutrients, 0172 - trace elements in filtered water, 2085 - dissolved organic carbon, 2020 - volatile organic chemicals, 2001 - pesticides in filtered water analyzed by gas chromatography/mass spectrometry, 2050 - pesticides in filtered water analyzed by liquid chromatography/ultraviolet light absorption spectrometry]
