SummarySummary

The system provided very good solids The system provided very good solids removal resulting in a reduction of total removal resulting in a reduction of total suspended solids by 80%, volatile suspended solids by 80%, volatile suspended solids by 67%, chemical oxygen suspended solids by 67%, chemical oxygen demand by 59%, and total nitrogen by 54%demand by 59%, and total nitrogen by 54%

SummarySummary

However, disproportionate deposition of runoff However, disproportionate deposition of runoff water increases surface soil nitrogen water increases surface soil nitrogen concentrations near the basin discharge tubesconcentrations near the basin discharge tubes

Elevation shifts of the inlets of the discharge tubes Elevation shifts of the inlets of the discharge tubes has caused disproportionate discharge to the VTAhas caused disproportionate discharge to the VTA
