: 1. Sediments
1. Sediment and suspended matter are the number one water pollutant based by weight
1: Levels nationally have risen rapidly due to accelerated erosion, construction & mining.
- reduce ability of organisms to find food,
- reduce photosynthesis, including that of important aquatic plants which sustain the ecosystems,
- clogs gills of fish and filters of filter feeders orgnanisms including shellfish
- carries pesticides, bacteria, metals and other toxins into the waterways and increases sediment loads,
- disturbs exisitn bottom sediments which are the feeding & spawning grounds of fish,
- silt fills lakes, reservoirs, harbors, an expensive and dangerous problem when flooding occurs
.Solution: actually quite simple.... this action is being implemented in many states now including MD......
"Govt. will pay farmers to help clean river
Considered the largest effort to revitalize an ailing river, the federal government will offer Illinois farmers up to $370 million to turn cropland into buffers against the sediment threatening to dry up the Illinois River.
Massive sediment buildups are jeopardizing both shipping and recreation on the 327-mile river that cuts a swath across Illinois.
Instead of traditional 10-year CRP contracts, the enhancement program pays more per acre for a minimum commitment of 15 years. The state will give bonuses to farmers willing to idle land even longer _ either 30 years or permanently.The state also will reward longer-term contracts by covering nearly all the costs of planting filters against silt runoff. The hope is more farmers will opt for trees, costlier but more effective than grasses.
Officials say up to 232,000 acres of the most floodprone and highly erodible riverside farmland could be returned to a more natural state in Illinois. Maryland and Minnesota are enrolling nearly 300,000 acres in the program; a half-dozen other states are readying proposals."
