Description Four sites on Bellingham’s Padden Creek were sampled for pesticides six times in 2001 and 2003 to complement water quality efforts in the watershed as part of the Whatcom Watersheds Pledge Program. Concentrations of the 19 detected pesticides were low.

The pesticides were as follows:
*Fourteen herbicides: dichlobenil, diuron, MCPP, 2,4-D, trichlopyr, pentachlorophenol, prometon, dicamba, simazine, MCPA, lenacil, terbuthylazine, atrazine, and bromoxynil
*Two herbicide breakdown products: 2,3,4,6-tetrachlorophenol and 2,6-dichlorobenzamide
*Two fungicides: chlorothalonil and 4-nitrophenol (fungicide breakdown product)
*One insecticide: diazinon.

Diazinon and chlorothalonil exceeded criteria for the protection of aquatic life during the 2001 sampling events.
