Recent reviews have concluded that there is no basis for changing the standards set by the EPA in 1971, even though the data base was insufficient then for a quantifiable, scientific definition of clean air. Examination of data shows that the United States does not have a sulfur dioxide problem. (Author/BT)

This circular provides current information for homeowners who must repair or replace existing on-lot sewage disposal systems. Site requirements, characteristics and preparation are outlined for a variety of alternatives such as elevated sand mounds, sand-lined beds and trenches, and oversized absorption area.
