During the 1978 irrigation season, 14 ground water samples were collected in the Central Platte region of Nebraska, an area known to have high nitrate-nitrogen (NO-N) levels, and analyzed for the presence of 13 pesticide residues. Atrazine levels ranged from 0.06 ..mu..g/liter to 3.12 ..mu..g/liter and were correlated to NO/sub 3/-N concentrations with a coefficient of r = +0.55. Nitrate-nitrogen concentrations were measured as indicators of deep percolation from irrigated lands and ranged from 17.1 mg/liter to 34.3 mg/liter. Alachlor levels ranged from <0.01 ..mu..g/liter to 0.71 ..mu..g/liter. The amounts of 2,4-D were indeterminate because of experimental problems. Levels of the herbicides silvex and EPTC were below the limits of detectability. Levels of the oragnochlorine insecticides endrin, ..gamma..-BHC (lindane), dieldrin, DDT and its primary metabolite DDE, heptachlor and its primary derivative heptachlor epoxide, and methoxychlor were all below the detectable limits of 0.005 and 0.010 ..mu..g/liter.
