2 Persuald et al., 1992. 3 Detection limit. Average phenoxy acid concentration were substantially higher during precipitation events than during dry weather for both streams sampled. Similar concentrations of phenoxy acids were measured during precipitation events in the wet pond, while the dry pond had levels below baseline values measured in the two streams. For the phenoxy acid herbicides, for which CWQG were available, concentrations measured were generally below the guidelines for the Protection of Freshwater Aquatic Life.
