SUMMARY

California. Water samples showed no detects of fenoxycarb, hydramethylnon, pyriproxyfen, dimethoate, and methidathion. Bifenthrin was detected in two samples at 0.495 and 0.778 parts per billion (ppb) at nursery sites F and G, respectively. Chlorpyrifos was detected in one sample at 0.06 ppb. Diazinon was detected in two samples at 0.059 and 0.06 ppb at sites F and E, respectively. Malathion was detected in one sample of nursery runoff at 0.07 ppb. Toxicity was tested at San Diego Creek at Campus Drive, an integrated site. This site was not significantly toxic (5 % mortality) to Ceriodaphnia dubia in the water collected. Additional water and sediment samples were collected from a mitigation filter strip planted with Canna to mitigate offsite movement of insecticides and nitrates. Bifenthrin and chlorpyrifos were detected in all water samples with a general trend of declining concentrations as the water passed through the filter strip. Sediment samples were positive for bifenthrin and chlorpyrifos with detections ranging from 776 to 1470 ppb and 27 to 80 ppb, respectively. SCOPE OF THIS MEMORANDUM This memorandum reports results of water sampling conducted by the Department of Pesticide Regulation (DPR), under interagency agreement with the California Department of Food an
