Abstract:This report presents an evaluation of wastewaters derived from concrete placement and maintenance and the
preparation of best management practices (BMPs). Investigation and documentation of existing practices was done
to ensure application to real situations and enhancement of constructability for all BMPs. Laboratory analysis of
test specimens was done to provide characterization of factors that are likely to positively or negatively influence
concrete wastewater composition. Evaluation of sedimentation and filtration through and absorption by sand and
geotextile materials provides a simulation of the known control techniques. Development of a constituent
occurrence and control model with a strong statistical base achieved through experimental replication supports
development of BMPs that are both environmentally protective and constructible.
