Weekend of E. Coli

Channel 7 reports that this weekend's boil-water order in Woburn, Massachusetts(1) has been rescinded after the smoking squirrel(2) was discovered inside the suspect water tank:

That tank is being taken care of, and the mayor has an interesting theory at what caused the problem, a small animal was found inside the tank.
Crews disinfected the water supply by pumping in additional chlorine to affected areas.

(1) PlagueBlog recommends against drinking the water in Woburn, Mass. under any circumstances, boiled or not, boil order or not, brown or not, eating through the pipes or not, for at least a hundred years.

(2) "Smoking squirrel" is a term of art and should not be taken literally. The report did not specify the animal found.
