Livestock Runoff vs. Water Quality

Livestock Runoff vs. Water Quality:

Livestock Runoff vs. Water Quality Andrew Blair Scott Haines Teddy Hoover

Definition of Water Quality:

Definition of Water Quality Testing Parameters to determine water quality: pH, Temperature, Suspended Solids, Fecal Coliform , Turbidity, Dissolved Oxygen, and Nutrients Poor Water quality impacts the Bay’s health Industries Affected: Seafood, Recreation, Residential

History:

History Started with Food Security Act of 1985 CREP-1986 In 1998 The Chesapeake Bay Preservation act was created

Preventions:

Preventions Riparian Buffers have been implemented to help deter nutrient runoff and soil erosion.

Chesapeake Bay’s Economic Contributions:

Chesapeake Bay’s Economic Contributions 2 billion dollars in sales 1 billion dollars in income More than 41,000 jobs

Economic Contributions:

Economic Contributions Fishing, Tourism, property, and shipping rates? Recreation and Commercial fishing? Sports Fishing in Virginia?

Main Components:

Main Components Blue Crabs Oysters Stripped bass (Rockfish)

Blue Crabs:

Blue Crabs Profit 1/3 of nations harvest Average annual commercial harvest is 55 million pounds $70 million Recreational crabbing costs Loss “ The overall crab trend since the 1990s has been a decrease in landings despite increased crabbing effort” CBF Severe crabbing restrictions License buy back plan Lost Jobs and profits

Oysters:

Oysters PROFIT Late 1800’s to mid 1900’s, thousands of jobs were out there Catching, selling, shucking, shipping, etc. Until mid 1980’s, oysters were the leading commercial fishery in the bay LOSS Natural Filters Reefs provide habitat Overharvesting, disease, and pollution $4 billion loss 6 oyster houses Population down 99%

RockFish:

RockFish PROFIT Most popular commercial fish in the bay $50 million of economic activity LOSS Imposed Moratorium in 1989 “Fisheries declines since the 1990’s indicate that early progrs reducing pollution hasn’t been sustained.”

Other Economic effects:

Other Economic effects Public health concerns: “Consuming tainted seafood or waterborne disease effects the amount of recreational consumers using the bay”. Property Values EPA study that clean water can increase property value by 25% Drinking water and other utility costs Cleaner water would mean less money spent on water treatment plants Going Green and other investments would create jobs.
