Evaluation of methods for diagnosing contamination in rural wells
Three diagnostic procedures were tested to determine their potential usefulness in identifying the extent of pesticide and nitrate-nitrogen contamination in rural wells. Daily sampling revealed little temporal variability in the quality of water from the monitoring wells or the contaminated water supply wells. The monitoring wells, though limited in number, identified one water supply well that was producing water with much poorer quality than the shallow aquifer was capable of producing. The chloride tracer test was successful in distinguishing contaminant entry via preferential flow from that through matrix flow in two of the case study wells. Nitrate-nitrogen and herbicide data showed little variability during the 8-hr period of well drawdown.
