Aluminum in precipitation, streams, and shallow groundwater in the New Jersey Pine Barrens
Aluminum appears in waters of the New Jersey Pine Barrens at concentrations of 0-200 micrograms per liter (volume weighted average, 105 micrograms per liter) in precipitation; 100-800 micrograms per liter (volume weighted average, 345 micrograms per liter) in streams; and 0-3000 micrograms per liter (volume weighted average, 468 micrograms per liter, and excluding one very acid well, 329 micrograms per liter) in groundwater. These levels are 10 times greater than in most terrestrial waters, except for the acidified waters of New England and New York. The pH of precipitation in this study averaged 4.0; of groundwater, 4.6; and of streams, 4.1. The total (acid reactive) aluminum deposited in the McDonald's Branch basin was 140 mg per sq meter per year over the study period, May 1978 to May 1980. Stream and groundwater outputs were 149 and 110 mg per sq meters per year, respectively. Increased precipitation, streamflow, and decomposing organic matter caused higher Al inputs and outputs in summer. In streams Al may be transported as an organometallic complex with dissolved organic matter, humic and fulvic acids. Groundwater Al concentrations depend on Gibbsite solubility in mineral soils and are pH dependent. 12 references, 5 figures, 1 table.
