It appears that the break-in to the Blackstone, Mass. water supply was the work of teens, rather than terrorists:
Two boys and a girl have been arrested in connection with the water supply scare in Blackstone. This comes as people there anxiously wait for test results to come back this afternoon. The system was shut down Tuesday after someone broke into the town’s water storage facility, sparking fears it may be contaminated.Police said all three suspects are 15 years old....
Police say the three teens broke into the facility Monday night. It houses a 1.3 million-gallon storage tank that supplies water to Blackstone and part of North Smithfield.
Someone cut barbed wire to enter the complex, cut the lines to an alarm, and then damaged an electrical panel and a vent at the top of the tank.
Authorities say the group left behind an empty, 5-gallon container that had an odor. Investigators were unsure whether it belonged to the water supply company that uses the facility.
OK, so it's not exactly Bierko dumping nerve gas into your home furnace, but the bad guys are watching. Since there's probably no way of securing every utility facility in the country against penetration, this sort of thing is going to have to be handled downstream through chemicals and filtration. Electrified and alarmed fences aren't a bad idea, though.
Neither is a decent stash of bottled water.
