To help managers, planners, and regulators determine when and where surface waters are likely to be adversely affected by organonitrogen herbicides; various data on the distribution of these compounds in the lower Kansas River basin are analyzed. It has been found that atrazine was the most frequently detected herbicide, it was found in the highest concentrations, and was most likely to exceed the maximum contaminant level. Methods to decrease the amount of atrazine that enters surface waters have been initiated.
