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?
