Table 1 0. Middle Atlantic Pollution Sources Affecting Harvest Limited- 

 Acreage, 1990 a ' b 



a. Acres are times 1,000; % is percent of all harvest-limited acreage in state. 



b. Since the same percentage of a shellfish area can be affected by more than one source, the percentages shown above 

 cannot be added. They will not sum to 100. 



took place in Buzzards, Great South, 

 Delaware, and Chesapeake bays, and 

 the Potomac, Chester, and Choptank 

 rivers. Declines were particularly 

 significant in the latter two rivers which 

 contain Maryland's major oyster seed 

 beds. However, Virginia's major 

 seed-producing area, the James 

 River, had an increase of over 1 1 ,000 

 acres of approved waters, almost all 

 upgraded from conditionally approved 

 status. 



All states except Delaware conducted 

 sanitary surveys and reclassification 

 activities between 1985 and 1990 that 

 resulted in slight increases in condi- 

 tionally approved waters. In Mary- 

 land, 63,000 acres were reclassified 

 from approved to conditionally ap- 

 proved during the period. New Jersey 

 was the only state to upgrade its 

 estuarine shellfish-growing waters 

 primarily on the basis of improved 

 water quality resulting from the 

 construction of new regional sewage 

 treatment plants and ocean outfalls.
