Plastic Mesh treatment disk about 2 inchs across.
Brenton Point RI Oct 15, 2011
On March 6th, 2011 the treatment plant at Hooksett, NH overflowed into the Merrimack River. Ordinarily this would have passed without notice except this overflow carried several million cute plastic disks with it. These tiny mesh disks provide bacteria a place to cling to while they go about removing phosphorous and other impurities. Eventually, they found their way down the river to the sea, where they began to show up on the beaches in New Hampshire, Massachusetts, Rhode Island, and Long Island in New York. There was no particular health problem as the sun and the scouring action of the surf pretty well cleaned them. I found this one on the beach at Brenton Point in Rhode Island on October 15, 2011 on a breezy Sunday afternoon. It’s one of the unexpected bonuses to Geocaching. Wendy and I found the geocache cleverly hidden on a bluff just above the beach.
