Dr. Knauss. I brought that point up with people in EPA and got 
the suggestion that they would at least consider it, but I am not 
aware of anything substantive that has been done along this line. 
Mr. ForsyTHE. Mr. Hughes? 
Mr. Hucues. Thank you, Mr. Chairman. 
Thank you, Dr. Knauss. I apologize for being late. 
I understand, however, in your direct statement that you do sup- 
port the 1981 recommendations of NACOA? 
Dr. Knauss. Yes; I continue to support the 1981 recommenda- 
tions. 
Mr. HuGues. Were you here during Mayor Koch’s testimony? 
Dr. KNauss. Yes, sir. 
Mr. HuGues. One of the things I requested from Mayor Koch for 
the record was the amount of hard metals, the amount of mercury 
and cadmium, in particular, and PCB’s that are going into the New 
York Bight out of New York City. Do you have that information, 
by chance? 
Dr. Knauss. The only information I have is the sort of material 
that NOAA has collected. We do not look for that information inde- 
pendently. 
Mr. HucHes. Would that be relevant to any studies that you 
have under way? 
Dr. Knauss. We presently have no studies under way with re- 
spect to the question of waste management, Mr. Hughes, other 
than the one we did last year. We have looked at it again and de- 
cided we still stand by our original recommendations. We have not 
made any other indepth study. 
Mr. Hucues. I understand that. My question was, Would that be 
relevant to your study? 
Dr. KNAuss. Yes. 
Mr. HuGHES. Do you have that information, by chance? 
Dr. Knauss. No; I do not. 
Mr. Hucues. You do not. OK. 
Part of your conclusion about the New York Bight is based on 
the fact that only 7 to 10 percent, I think, is the figure that has 
been used, of the overall pollution problem in the New York Bight 
is attributed to sewage sludge. That is projected to increase signifi- 
cantly as more waste water treatment facilities come on line. Have 
you factored that into your conclusions? 
Dr. Knauss. That is correct, sir. It seems to me, as we heard 
from New York City today, they are going to have two major sys- 
tems on line here in the next few years, which will indeed decrease 
the amount of untreated sewage which will flow into the New York 
Bight area. 
Mr. HuGues. The fact of the matter is sewage sludge is going to 
increase. It is not going to decrease. 
Dr. Knauss. That is right. The more secondary treatment plants 
we have in this country, the greater the amount of sewage sludge 
we will have to dispose of. 
Mr. Hucues. I agree. As I understand, basically your conclusion 
is that we should not phase out the New York Bight dumpsite, the 
12-mile site; that at the present time it is not in your judgment, 
sufficiently distressed to phase that out? 
Dr. Knauss. That is right. That is my personal view.
