Comparison of sewage sludges of New York City and Philadelphia 

 show that Philadelphia sludges can more readily be used in land 

 application systems than those from New York City. The 

 essential difference is the metal content. The availability of 

 large areas of strip mine spoils in Pennsylvania also enhances 

 the need for this type of sludge management program. Even 

 though these mine spoil areas exist, we believe that residents 

 in some of these areas are becoming more reluctant to receive 

 this gift from Philadelphia. The elimination of available 

 application land may cause Philadelphia to reevaluate their 

 alternatives. 



As stated previously New York City is more than willing to 

 participate in the search for answers that will ultimately lead 

 to environmentally sound sludge management programs. Toward 

 this end, we were happy to provide this response at this time 

 and will gladly provide assistance in any future inquiries.
