The shelf valley may be acting as a conduit as suggested by the higher R values observed on the southern flank of the valley. Alternatively the fine material may simply be dispersing in a broad pattern offshore and accumulating in the topographic lows. Regardless of the mechanism involved the observed distribution strongly suggests that a significant proportion of the dumped sewage sludge is being trans- ported away from the coastline into deeper water. In addition to the data of figs. , samples from the MESA substrate monitoring program (locations shown in fig. ) and recently collected samples from the south shore of Long Island (locations shown in fig. ) have also been analyzed for TOC and carbohydrates. Pre- liminary results (Table and ) indicate that pockets of black mud, rich in TOC (~5%), do exist within 1^ miles of the Long Island beach. This TOC concentration is similar to that found close to the actual dump- site. Within one-half mile of the beach other pockets of mud were found to contain sediments having a TOC concentration of approximately 2%. The more extensive sandy sediments in the immediate vicinity were observed to have a TOC varying from to fl00<* Roy,,,., ° "'»» control.
