BABOOSIC LAKE WASTEWATER
DISPOSAL FEASIBILITY STUDY
TOWN OF AMHERST, NH
The Town of Amherst owns two parcels of land with a total of 1.5 acres in the vicinity of Baboosic Lake in Amherst, NH. The potential for inadequate or failing on-site subsurface disposal systems exists, thereby threatening the water quality for Baboosic Lake. The objective was to determine the feasibility of utilizing these parcels of land for a community wastewater disposal system that would serve selected residents in the vicinity of the Lake.
