Stormwater from four watersheds in the Houston area was monitored over a three year period. Land use in the watershed included undeveloped forest, developing forest, fully-developed residential and mixed commercial-residential. Chemical parameters monitored included suspended solids, oxygen demand, organic carbon, nitrogen, phosphorus, dissolved oxygen, pH, specific conductance and chlorinated hydrocarbons. Indicator and pathogenic bacterial species were enumerated as well as aquatic and edaphic algae species. Disinfectant demand and algal bioassays were also conducted. Relationships have been developed between stormwater runoff quality, quantity and land use in an effort to predict pollutant loads. The Storm Water Management Model (SWMM) was modified to describe the processes occurring in the watershed.
