Caption:  The Source Table wq_petaluma_diazchlor_ptp_1998.xls.db shows water quality monitoring results from the Petaluma River watershed during 1998. The parameters analyzed included diazinon (ppb and ng/L), chlorpyrifos (ppb and ng/L), electrical conductivity (µmhos/cm), pH, and temperature (C). Note that values of diazinon and chlorpyrifos below 30 ng/L should be considered "non-detect," due to the practical laboratory reporting limit. Data were collected by Petaluma Tree Planters. See COMMENTS column for notes on sampling events.

 50 rows of a possible 4247 have been displayed.
