2017 Water Quality Report

In 2017, the Center for Environmental Research and Coastal Oceans Monitoring (CERCOM) visited 9 locations in the Great South Bay to monitor for dissolved oxygen (DO), pH, salinity, clarity and temperature. These parameters are critical in determining long-term water quality conditions for Long Island's ecosystem health.

Figure 1

Tables shown represent each year's (2014-2017) site and total water quality parameter averages. Each of the 9 sites monitored in the Great South Bay has its own yearly specific average. Those averages make up the years' total average, as shown in the last column.

The graph shows the trend for the Great South Bay's dissolved oxygen levels from 2014-2017. The dissolved oxygen values (both surface and bottom values of DO) for 2017 have been robust overall and outstandingly consistent. Graph shows a general increasing trend.

Figure 3

The graph shows a four-year trend for the Great South Bay's pH levels. pH levels range from 6.02 to 8.06. pH levels are collected from 9 locations within the Bay.
