Alert from the City of Gloucester:
Caution Regarding Sewer Treatment Disks — Update March 15, 2011
Thousands of discharged disks from the Hookset, NH wastewater treatment plant have washed up on local shores including Coffins Beach, Wingaersheek Beach, Long Beach and private areas along the coastline.
The city is formulating its clean up plan, and in all likelihood will require the assistance of citizen volunteers.
If disks are handled, rubber gloves must be worn and hands should be washed or sanitized immediately afterwards. Disks can be placed in plastic bags and dropped off at the Dept. of Public Works on Poplar St. for disposal.
Please keep pets away from the disks.
You can get further updates from the city of Gloucester website.

Good Morning Gloucester 
How disgusting and gross, and at first glance of the photo, I thought they were sand dollars.

I know it’s awful! I haven’t been to any beaches in a few days, I hope ours aren’t this bad. I’ll pick up any I see and bring them to the DPW.

Sad, I thought they were sand dollars too.

We found two at Niles Beach yesterday, so look for them in the Harbor as well. All plastic is bad, and I hope people will pick up other trash as well as these disks.
