Water quality and groundwater levels were monitored in the area of a field where municipal wastewater is applied by spray irrigation. The area irrigated is 4 miles southwest of Tallahassee, Florida, on land covered in part by pine forest and in part by selected grasses and forage crops. Hydrologic and geologic data were collected from March 1972 through June 1981. Hydrologic data include groundwater levels, water quality, and spray-irrigation rates. Measurements of groundwater levels were made at 60 wells. Water-quality samples were collected at 1 municipal wastewater effluent site, 3 springs, 17 soil sites, and 64 wells. Water-quality data include.physical, chemical, and bacteriological analyses. Geologic data include geophysical logs and lithologic descriptions of 34 wells.

Increases in the concentrations of chloride and nitrate nitrogen in ground water have resulted from land application of secondary-treated municipal sewage southwest of Tallahassee, Florida. The increases occurred predominantly during periods of above normal application rates. This result is based upon a data-collection program which began in 1972, 6 years after the initial application of treated sewage. The data collection period for this report is 1972 through June 1981.
