The 106-Mile Dumpsite, a deep ocean site located 106 miles southeast of New York, receives sewage-treatment sludge from several municipalities in New York and New Jersey. The site is occupied predominantly by slope water, however, incursions of shelf water and warm-core rings occur periodically. Satellite infrared data are used to determine which water masses are present at the time of each dump. Records of sewage sludge dumping at the site are obtained from the U.S. Environmental Protection Agency (EPA). This report correlates data regarding volumes and dates of dumps at the site with information on the water masses present at each dump. It is the latest in a series of summaries covering the last fifteen years. A summary of the amounts of wastes received by each of the three principal water masses for 1990 is presented. In 1990, 2,164 X 106 gallons of sewage sludge were dumped at the 106-mile site. Approximately 70 percent(by volume) of the sludge was disposed of in slope water, 23 percent in shelf water, and the remaining 7 percent was received by warm-core rings.
