is a chapter of 10369544 Artificial recharge of groundwater
In a rapid-infiltration land treatment system, wastewater is treated as it percolates through the soil. The wastewater is applied to moderately and highly permeable soils (such as sands) by surface spreading in level basins or by sprinkling. Treatment is accomplished by biologic, physical, and chemical means within the soil. The need for definitive information on the extent of soil treatment during rapid infiltration has been recognized. Rapid infiltration is effective in removing many wastewater constituents such as suspended solids, BOD, ammonium-nitrogen, phosphorus, bacteria, and virus and is less effective in removing other constituents such as nitrate-nitrogen, trace organics, and trace minerals. The constituents addressed in this chapter include trace organics, inorganics (those covered by drinking water standards), and microorganisms. For these three classes of constituents, the health effects, removal mechanisms, and removals in existing rapid-infiltration systems are discussed. (See also W87-08137) (Lantz-PTT)
