A discussion on the issue of salinity
Salinity, the saltiness of the water, was a major water quality issue for 24 of the 74 assessed basins (32% of basins) in the nlwra 2001 high levels of salinity occur in catchments where a large proportion of land has been cleared increased salinity in ground and surface water will worsen the irrigation salinity problem that many farmers.

As some discussion of the results, salinity will increase over the entire 200-km length of the lower st johns river due to sea-level rise in general, risen offshore water levels will enable more saline waters to flux into the river, while subsequently pushing back on the freshwater discharge coming down from upriver, which together will cause salinity in the river to increase the salinity.
