Scott County Snapshot Sampling Results – October 8, 2002 (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
*Parameter measured at Davenport Water Pollution control long-term sites only.
**Parameter measured at non-Davenport water Pollution Control long-term sites only.
The following pesticides were also analyzed at the 42 Davenport water Pollution control long-term sites in October 2002, however, no detections were reported:    cyanazine, alachlor, metribuzin, butylate, trifluralin, acetochlor, simazine, ametryn, EPTC, prometon, propachlor, dimethenamid.
