Evaluation of detention-basin performance in the Piedmont region of North Carolina
Technical Report
·
OSTI ID:6970877
Results are summarized of a stormwater sampling program conducted on three existing urban wet detention ponds in the Piedmont region of North Carolina in the city of Charlotte. These ponds were not originally designed for water-quality control. A total of eleven storm events was monitored. Runoff samples were analyzed for total suspended solids, total and ortho phosphorus, total Kjeldahl and ammonia nitrogen, and metals of iron, zinc, copper, and lead. The removal efficiency of pollutants for each detention pond was computed as the percent difference of the total pollutant mass entering and leaving the detention pond. A U.S. EPA model was employed to derive a relationship for estimating the size of detention ponds to achieve targeted levels of water-quality improvement.
