An ecologically planned community (The Woodlands, Texas) has adopted a unique water management plan designed to avoid adverse water quality and hydrological effects due to urbanization while benefiting from the existing natural drainage. Data on water quantity and quality were collected during dry weather and during stormwater runoff. To supplement the prime study site, stormwater samples were also collected at watersheds in the Houston area. Parameters monitored during the reporting period were as follows: rainfall, streamflow, chemical oxygen demand (COD), soluble organic carbon (SOC), biochemical oxygen demand (BOD), ammonia (NH3), nitrate (NO3), nitrite (NO2), total Kjeldahl nitrogen (TKN), orthophosphates (ortho-P), total phosphorus (TP), dissolved oxygen (DO), pH, turbidity, total suspended solids (TSS), and specific conductance. Data were analyzed for water quality relationships in an effort to predict pollutant loads according to land use. Significant relationships were observed between total volume of runoff and total load of various pollutants. The load-runoff relations are a function of the type of land use activity in the watershed and have been used to simulate stormwater quality responses.
