All treatments showed some reduction in runoff volume, but the homeowner treatment with rainwater harvesting showed a significant reduction of 43% compared to 19% and 14% for the ET and SM treatments.<\/p>\n

The concentrations of pollutants in the runoff for pH, EC, nitrate nitrogen, orthophosphate, and total suspended solids were also compared. There were no specific trends of concentration reduction in any of the treatments for any of the pollutants since this BMP is mainly a volume reduction BMP.<\/p>\n
