Notes:
: A survey of 34 open hand dug wells was performed in the Senegal River basin of West Africa. Nitrate concentrations were determined on the well water samples over a six-month period. With the exception of two wells, the wells indicated varying levels of nitrate contamination. The range of concentrations was 0.10 to 880 mg/I as nitrate. These data when compared to physical characteristics, land use, and age using a chi-square analysis did not suggest any strong association. The fact that these wells are open and in a semiarid climate may be of such importance that the previously considered factors are of minor relative importance. Contamination may be primarily the result of foreign matter entering the well mouth.
