I am a citizen of Rockbridge County and have learned that there is little regulation of suspended solids in the Virginia water quality regulations.  I hope that this will change as the environmental damage that is caused by those suspended solids is severe.  Of course there are natural / environmental causes of turbidity but there needs to be some regulations crafted (for activities that can be regulated) in and around water bodies.  If monitoring detects a rise in non environmentally caused activities, then actions need to be taken to limit or regulate those activities.  Thanks!
