A new environmental report says that improvement for habitat areas in the Delaware Inland Bays has stalled.
It also reports that the water quality in the bays is still rated fair or poor.
WBOC says that the report by the Delaware Center for the Inland Bays found the largest non-point source of nutrient pollution came from fertilizers, animal waste and storm water runoff.
But the report notes that of the original 13 point sources of discharges into the bay are only two left.
These are the Allen Harim plant near Indian River and the wastewater treatment plant for Rehoboth Beach which is supposed to be shut down in 2018.
Chris Bason, executive director of the Center told WBOC that he is optimistic about continuing improvements in the bays.
But he also notes that the state is seeing the effect of climate change on the inland bays including shoreline erosion and flooding.
