ABSTRACT
Groundwater in shallow aquifers that supply water to dugwells in crystalline
terrain of the Visakhapatnam region, Andhra Pradesh, have higher concentrations
of flouride (F) than those of borewells from deep aquifers. Factors for
variation in F content between the two aquifer water types are discussed.
The relative merits of the shallow water for potability are pointed out
with respect to F concentrations and public health.
