I don't know for sure but I suspect that there might be some sort of effect
perhaps not as great as for sea water. The source of the water would have
some role - if the lake, river etc was fed by an ancient aquifer then
probably there would be some problem....Discrepancies in dates on carbonates
in general are a phenomenon - ostrich eggshell for instance seems to produce
dates which differ from allied charcoal ones by regrettably varied amounts.
