This sample (taken from the Appomattox river) was collected at 9:00 am on 01/14/16. Distance from Hercules chemical plant is less than .25 miles.
1) Aminopyrazole derivatives @ 410.92 nm
2) dipyrrometheneboron difluorides (BDP)
Suspected organophosphates, but I need to fashion a better prep for detection in the sample.
protocol question: Sampling-Are you sampling upstream of the suspect site to ensure no previous C(ontamination)? What is your sampling CONTROL?
