Fifty two stations were monitored over twelve weeks of each of the summers of 1988 through 1990 to provide the 79th, 80th, and 81st Annual Summer Water Quality Surveys of New York Harbor. Coliform bacteria continue to exhibit significant long-term improvements throughout the harbor due to water pollution control plant construction and upgrades. Only 4% of stations were out of compliance with coliform standards in 1990, with exceedances confined to waterways heavily impacted by combined sewer overflows (CSO's). In 1990, average summer dissolved oxygen (DO) met state standards at 94% of surface, and 85% of bottom sites; however many sites contravened DO standards at least once. While average DO compliance in 1990 was significantly better than any time since at least 1986, 1988 and 1989 were noticeably worse, particularly in waterways prone to phytoplankton blooms and density stratification. Nutrient and chlorophyll a concentrations displayed spatial trends.
