Table 3.7.

Water quality guidelines (WQG) used for evaluation of 1997 RMP results. Dissolved trace element water quality criteria are from the Proposed California Toxics Rule (U.S. EPA, 1997). Total trace element water quality criteria are from the Basin Plan (SFBRWQCB, 1995). Organic compounds are listed on a total (dissolved + particulate) basis. Units are in µg/L. Bold and italicized values are hardness dependent criteria and were calculated using a hardness value of 100 mg/L.

^A	Silver value is the instantaneous maximum.
^B	Nickel saltwater value is 24-hour average.
^C	Selenium values are region-specific criteria as outlined in the National Toxics Rule - 1992: values are for total recoverable selenium results and freshwater criteria apply to the whole Estuary.
^D	Zinc saltwater value is 24-hour average.
^E	Chlorpyrifos and mirex are not listed in the proposed CTR but EPA criteria do exist for them.
^F	Total PAHs is not listed in the proposed CTR but an EPA criterion does exist for it.
