S. has generally concentrated on disposal systems, although some efforts have been expended on treatment systems prior to disposal of wastewaters. Treatment studies have primarily centered on: 1. The effects of treatment on disposal 2. The performance of alternative treatment devices 3. Modifications to septic tanks. The influence of treatment efficiency on subsurface soil disposal has been studied by several investigators. There is general agreement that improved effluent quality can result in less-intensive clogging of coarser, unstructured soils, such as sands.

KREISSL 46 The initial effort was to develop an overall understanding of the state-of-the-art. This included analysis of wastewater characteristics, both in quantity and quality, transmission, treatment, and disposal. These efforts were directed at both on-site treatment and disposal and collection from small groups of homes to entire communities for centralized treatment. The remaining discussion relates only to the on-site treatment and disposal of domestic wastewater aspects of the USEPA research program.
