Bottom Line – WASA’s biosolids land application program is still Bottom Line – WASA’s biosolids land application program is still viable and cost effective – BUT the long-term viability MAY be viable and cost effective – BUT the long-term viability MAY be impacted by further public concern and anti-biosolids groups.impacted by further public concern and anti-biosolids groups.
