Muscatine County Snapshot Sampling Results – May 13, 2003 (continued).
mg/L = milligrams per liter (or parts per million – ppm); µg/L = micrograms per liter (or parts per billion – ppb)
CFU/100 ml = Colony Forming Units per 100 milliliters of water
The following pesticides were also analyzed at the 13 sites, however, no detections were reported: alachlor, metribuzin, butylate, trifluralin, simazine, EPTC, prometon.
