Cadmium: Key FindingsCadmium: Key Findings
Use of cadmium has changed dramatically over the last 20 years – (75% used for Ni-Cd batteries)
Cd flows through the economy larger than inputs to the harbor – discrepancy between IE & MB assessments
Assumption that discrepancy could be explained by battery recycling put to the test (survey)
Survey finding: low recycling rates for regionDiscrepancy explained by MSW management
practices – NYC exports to other regions; NJ does notCampaign to increase battery recycling rates based on
precautionary principle System boundary - Impacts are not always regionalImpacts on Harbor depend on current practices
PCBs: Industrial Ecology analysisPCBs: Industrial Ecology analysis
US PCB production (1929-1975) = 568,000 T 77% of PCBs produced for use in closed systems (transformers, large & small capacitors)10% semi-open applications (hydraulic, heat transfer fluids)13% open applications (paint, carbonless paper)
Production generally prohibited since 1977
PCB in closed applications – use permitted
Last account of PCBs in use conducted in 1980s:70% of PCB transformers at non-utility facilities ~ 79,000 T30% of PCB transformers at utilities ~34,000T80% of PCB contaminated transformers at utilities ~ 120T85% of PCB large capacitors at utilities ~ 40,000TSmall capacitors: 870M in 1977 (ea. w/ 0.05 lb; total = 20,800T)

Small PCB CapacitorsSmall PCB CapacitorsOver 100 million small PCB capacitors produced in US
PCB capacitors sold in the watershed: 5.2M – 5.8M Average quantity: 24 grams each~ 120 - 140 tons PCBs in small capacitors in watershed
High uncertainty about their fate If only 10%-30% still in use - 12-14 tons PCBs
Small PCB capacitors are not regulated as hazardous waste and may be sent to landfills or municipal waste incinerators
Landfills that accept “fluff” material (e.g.metal shredding) have higher concentrations of PCBs in leachate
Limited funding for PCB small capacitors collection programs
Limited public awareness about household products containing PCBs
Products containing PCBsProducts containing PCBs

Inadvertent Production of PCBs:Inadvertent Production of PCBs:
PCB 11 or 3,3’-dichlorobiphenyl is a significant congener in ambient waters in the NY/NJ Harbor, Long Island Sound, and the New York Bight. PCB 11 is estimated to represent 10 to 20% of total PCBs entering the NY/NJ Harbor Inadvertent production of PCB 11 is related to pigment manufacturing. The effluent at various NY & NJ wastewater treatment facilities are dominated by PCB 11
Federal rules state that non-Aroclor PCB concentrations discharged to water from manufacturing or processing sites are limited to less than 0.1 ppm for any resolvable gas chromatographic peak
Contaminated Sites: Superfund, Contaminated Sites: Superfund, Brownfields and LandfillsBrownfields and Landfills
179 Superfund sites in region (64 in NY & 115 in NJ)550 Brownfields sites in NJ (at least 34 sites in NY, but no information to assess whether they have PCBs)60 contaminated landfills in NJ (no information for NY)26 “other contaminated sites” in NJClean up schedule of Superfund sites has slowed down to less than half the rate of the 1990s when an average of 87 sites were being cleaned each year. In 2003 only 40 Superfund sites were cleanedFunding drying up – taxpayers money being requested to fund Superfund program in 2005Remobilization of PCBs from contaminated sites:

PCBs: Mass balance findingsPCBs: Mass balance findingsOngoing releases from upriver (including the Hudson
River Superfund Site) account for ~50-55 % of PCB inputs to the Harbor

Parking Lot SealantsParking Lot SealantsBackground:
• Sealants used to protect asphalt surfaces (i.e. parking lots and driveways).
• Two types of sealant: Asphalt based and Coal-tar based. (coal-tar sealants predominately used east of the Rockies)
• Concern with coal-tar and asphalt based sealants:
• Contain PAHs
• Abrade from surface over time and are transported via runoff.
• Data:
•Peter VanMetre, U.S. Geological Survey
• Robert P. DeMott, Pavements Coating Technology Center
Parking Lot Sealants, cont.Parking Lot Sealants, cont.
Problem: how do yields change over time?
Parking lot Sealants
Yield (µg PAH/m2 /rain event) = 946 (according to Mahler et al, 2005)
Coal tar sealant consumed in the watershed area (gallons/yr) = 5,800,000
Can we calculate a release in the watershed?
25 kg PAH for 1 rain event in the watershed.
~118 days of rain per year in watershed area
What if only asphalt based sealant was used?
11 kg PAH for 1 rain event in the watershed.
