NBMA - Biosolids Quality Committee

Biosolids Quality Committee

Purpose
The Biosolids Quality Committee (formerly Pretreatment/Source Control) provides information to agencies and the public on ways to achieve cleaner biosolids through process control. The Committee encourages participation of current (active and inactive) and potential members at meetings, conferences, and workshops. It promotes comprehensive program implementation by members to reach the public.
