Thesis (Ph.D.)--Columbia University, 2006.

Cl- and SO42- budgets were developed for the Cascade Brook watershed within Black Rock Forest, in the Hudson Highlands, NY. Additionally, temporal trends in [H+], [NO3 -], [NH4+] and wet deposition were examined. Patterns in Cl- wet deposition indicated that sources in addition to sea-salt aerosols contribute &sim; 24% of mean annual Cl- wet deposition. These additional sources probably include HCl emissions from: (1) coal fired generating stations; (2) waste incineration; and, (3) HCl production from sea-salt dechlorination. Cl- export budgets for Cascade Brook yielded a Cl- export-to-Cl - wet deposition ratio of 3:1 indicating that there was at least one significant source in addition to wet deposition contributing Cl- to Cascade Brook. We conclude that additional Cl- sources contributing appreciable amounts to Cl- export include dry deposition and mineralization of soil organic matter.

520 $a Cl- and SO42- budgets were developed for the Cascade Brook watershed within Black Rock Forest, in the Hudson Highlands, NY. Additionally, temporal trends in [H+], [NO3 -], [NH4+] and wet deposition were examined. Patterns in Cl- wet deposition indicated that sources in addition to sea-salt aerosols contribute &sim; 24% of mean annual Cl- wet deposition. These additional sources probably include HCl emissions from: (1) coal fired generating stations; (2) waste incineration; and, (3) HCl production from sea-salt dechlorination. Cl- export budgets for Cascade Brook yielded a Cl- export-to-Cl - wet deposition ratio of 3:1 indicating that there was at least one significant source in addition to wet deposition contributing Cl- to Cascade Brook. We conclude that additional Cl- sources contributing appreciable amounts to Cl- export include dry deposition and mineralization of soil organic matter.
520 $a Decadal trends (1981-2003) in precipitation chemistry near Cascade Brook indicate that SO42- wet deposition decreased by &sim; 37%; a pattern consistent with decreases in SO2 emissions upwind of Black Rock Forest. In addition, SO42- wet deposition per unit area represented &sim; 20% of local and regional SO2 emissions, indicating that appreciable amounts of S were probably deposited locally as dry deposition or as wet and dry deposition at sites beyond the northeastern USA. An independent estimate of S dry deposition near Cascade Brook, derived using a dry deposition inferential technique, indicated that S dry deposition contributed 50% as much S as SO42--S wet deposition. Finally, temporal patterns in Cascade Brook SO42- surface water export indicated that: (1) appreciable amounts of S are probably stored temporarily within the Glycerine Hollow wetlands; and (2) the &sim; 2.8-3.1 ratio of SO42- export-to-SO4 2- wet deposition suggested that sources other than wet deposition contribute significant amounts of S to the watershed. Using a watershed mass balance approach, we estimate an upper limit for S dry deposition of 14-17 kg S ha-1 yr-1, which was &sim; 3.5-4.3 times the amount of S dry deposition derived from the inferential technique (4.0 kg S ha-1 yr-1).
