I'd have to question that, too. I work for my local township, in the same building for the past eleven years. Not ONCE has the water been tested in all that time. In fact, when I started seeing brown water coming up in the toilets and water fountain, they replaced a backflow pump that hadn't been serviced in what the plumbers described as "probably thirty years." Even after replacing the pump, they advised me to disconnect the water fountain and NEVER drink any of the water in the building.
