P&R tested the water in the "swimming pond" recently, and I am pleased to say it is much better than when it was first tested (around June 1).
Even though the pond still tests positive for BGA, the expert who did the testing feels it would be safe to reopen it for dog swimming. However, P&R feels it would be prudent (their phrase was "abundance of caution") to keep the pond closed at least through the summer, since it is possible spells of hot weather may bring elevated levels of BGA.
