Alluvial aquifer.

Conditions in the alluvial aqui-fers (fig. 9) indicate that ammonia in shallow urban ground water originates, at least partly, from deg-radation of organic matter most likely derived from human activi-ties. Substantial amounts of organic matter are available in the soil, silt, and clay above the aquifer and dis-solved in water within the aquifer.
