designation for dredge spoil disposal. The New England Division of the COE recently has 
been monitoring the area as part of their DAMOS Project. 
Recently estimated loadings from all sources for the following pollutants into 
Massachusetts Bay are listed below: 
SOURCE TONS PER YEAR 
PCBs 4,400 
Chlorinated hydrocarbons 2,100 
Petroleum hydrocarbons 1,760 
Cadmium 88 
Copper 1,760 
The critical issues that face Massachusetts Bay as perceived from EPA's point 
of view are the following: 
1. Cumulative impacts of large municipal wastewater discharges 
relative to the loadings of metals, toxic contaminant, and 
organic enrichment. 
2. The incidence of fish disease throughout the Bay and possible 
indications of stressed biological communities within 
Massachusetts Bay and Boston Harbor. 
3. The cleanup of Boston Harbor, of which the following speakers 
will give much more detail. 
EPA Region I feels that a constituency that transcends localized interest 
needs to be developed for the environmental issues facing Boston Harbor and 
Massachusetts Bay . 
I would like to thank you, and I will be happy to take some time for questions. 
Question and Answer Discussion 
Dr. Brown: What do you think the best route would be to develop such a 
constituency in the next two years? 
K. Castagna: Well, as you mentioned in introductory remarks, there's been a 
tremendous amount of media attention on the cleanup of Boston Harbor. I think what 
would be useful is more public information on the interaction of Boston Harbor and 
Massachusetts Bay and how the Harbor and the state of pollution in the Harbor affect the 
Bay on the whole. The Bay, itself, is conceived of as a regional resource, and as we noted, 
many beaches and recreational facilities are in both the Harbor and the Bay itself.
