Other anticipated high priority problems are excessive nutrient and sewage inputs to estuaries, principally from land-based sources. The health of estuary ecosystems is threatened by: 1. increased nutrients and algal blooms 2. loss of habitat and biodiversity 3. contaminants and pollutants 4. accelerated rates of sedimentation 5. disturbance of acid sulfate soils 6. changes to freshwater and tidal flows 7. invasive species 8. climate change. These activities can contribute to unsafe drinking water, beach and shellfish bed closings, harmful algae blooms, declines in fisheries, loss of habitat, fish kills , and a host of other human health and natural resource problems. In many coastal areas, the estuaries have been affected by human activity for hundreds of years, making it difficult to establish “natural” baselines of water and sediment quality standards.
