Details:	SUMMARY: Late 2,4-D sample submittal DETAILS: Lake Oswego took quarterly samples, but the lab and WS did not report them to the state in the first two quarters of the year. Also, Kari looked into the possible source of the 2,4-D detection. She thinks that the initial flushes of post-summer 2007 were after the September sample, making it less likely that it was upstream tributary contamination. However, the herbicide applications near the sample station had not been applied few several months, making that possibility unlikely as well… Conclusion: unknown ACTION NEEDED: none
