A highway construction project in the Houston area was monitored from preconstruction to near completion to determine the type of pollutants that leave the site. The effectiveness of temporary sediment controls (TSCs) for pollutant control was also monitored. Most nutrients and metals appeared to be negligible pollutants as their concentrations in stormwater leaving the site were relatively unchanged when compared to ambient levels in the receiving waters. Suspended solids and turbidity were the most significant measured parameters that were observed to change during rainfall. The results of the on-going work will be presented. Currently, the data indicate that there is little or no effect of construction on the receiving water for the sample sites analyzed to date.
