HYDROLOGIC data collected between 1970 and 1975 show (a) that saline seeps are sustained by local recharge, i.e. by soil water that percolates past the root zone of the adjacent upslope landscape, (b) that seep development is closely related to recent climatic and cultural events, and (c) that hydraulic control can be quickly accomplished with interceptor drains. Effluents from two drains were saline with nitrate concentrations consistently high enough to be hazard-ous to health of humans and livestock.
