Dissolved chlorpyrifos concentrations in water
(ppq) at 16 RMP stations sampled in January, April,
and August 1997.
= not analyzed,
= below detection, and Q = outside the QA limit.
Concentrations ranged from below detection to 900
ppq (see Appendix B for MDLs). The highest
concentration was sampled at Sacramento River (BG20)
in April. Average concentrations were highest (595
ppq) in the Southern Sloughs in August and lowest
(54 ppq) in the Southern Sloughs in January. There
are no water quality criteria for dissolved chlorpyrifos.
