Hundreds of dead greyhounds reportedly buried in the 1970's across from the Seabrook, New Hampshire dog track were speculated to be the cause of E. Coli bacterial contamination recently discovered in the town's water supply...

Two wells near the track were found to be the cause of the contamination. One resident claimed 1,000 greyhounds were buried at the site in the 1970's. Water Superintendant Warner Knowles questioned that figure but said he had no firm numbers. Both wells are now permanently closed.
