Um..there is another problem with water screening now days. The Clean Water
Act has required most construction sites to create sedimentation ponds to
prevent waste water from carrying sediments down stormdrains and creeks. This also
applies to archaeology water screening and the City of San Diego has required
sedimentation ponds, sandbagging, and runoff collection areas. There is a
saying in the Navy that you cant scoop a bucket of water and then drop it back
into the sea without getting Clean Water Act compliance reports.
