Total DDT concentrations in water (ppq) at 16 RMP stations sampled in January, April, and August, 1997. Concentrations ranged from 100 to 3,519 ppq (see Appendix B for MDLs). The highest concentration was sampled at San Jose (C-3-0) in January and the lowest at Golden Gate (BC20) in August. Average concentrations were highest (1,755 ppq) in the Northern Estuary in January and lowest (204 ppq) in the Central Bay in August. Water quality objectives do not exist for total DDTs, although individual compounds have criteria.
