| Summary: | 0.75, -0.67, and -0.63 where found between the sum of target 5.0 ppm N, and 0.5 ppm N for available phosphate, ammonium, ammonia), nitrate (plus nitrite), available phosphorus, total analytes and ammonium, available phosphorus, total Kjeldahl and nitrate, respectively. Ammonium concentrations were as area was naturally enhanced with elevated nutrient levels. as 75 ppm P during December, 1994. Available nutrient levels between the nutrient levels and the degradation of the brackish marsh impacted by an oil spill and fire in which the cleanup during the spill response. Sediment samples, collected over a period of one year, were analyzed for correlation coefficients suggest a strong interdependency declined over the period of the study indicating that the degradation of the oil. downstream where it was ignited inside a flooded house and either nutrient rich sediments from erosion due to the flood Flood waters during October, 1994, ruptured a group of from construction activities involved in building the high as 40 ppm N and available phosphorus levels were as high into the San Jacinto River near Houston. This spill traveled Kjeldahl nitrogen and total Kjeldahl phosphorus. Available nitrogen, and total Kjeldahl phosphorus, respectively. These nutrient concentrations were initially high and then declined nutrient levels provided favorable conditions for the nutrients and petroleum hydrocarbons. Natural levels were obtained by monitoring the nutrient values over a year after or ashes from the fire. Also, the disturbance of the site perturbations observed. During the study, the sum of total petroleum target analytes decreased from approximately 160 petroleum. The data suggest that the naturally elevated pipelines which released gasoline, diesel fuel and crude oil ppm to less than 10 ppm. Correlation coefficients of 0.76, sampling structures could have contributed to the system had been enriched. the event. Nutrients monitored include ammonium (plus Theories about the source of enrichment include deposition of This research involves a study of the natural recovery of a to presumed background levels of approximately I 0.0 ppm P, was allowed to bum for 7 days.
