Paul;

Yes it is however, there is a paucity of details. Are these just 
shells or intact organisms scallops? The report says, in part, "They 
discovered the shells' shape and chemical makeup neutralizes pH and 
also helps filter out coliform bacteria, sediment and heavy metals." 
(Emphasis added).

Anyone have any insights?
