pressing questions surrounding the death is how could a body enter the drinking supply and remain undetected for a day and a half without sounding alarm? the answer was in the tank, the sensor defined to warn of water displacement wasn't working. so, when she fell or was pushed into the water tank, no alarm sounded to warn something weighing 175 pounds entered the water. it could have been 175 pounds of a bilogical weapon as a body. this violation led to further questions. if a body con contaminates one million gallons of water without alarm, what else could be in the drinking supply? in light of the never attacks in nearby manhattan, the chemicals like chlorine, a deadly gas used as a chemical weapon in the first world war, were they used properly and secure? the pbwc is a typical facility and one had to wonder, are water supplies in the facilities vulnerable to contamination by natural, accidental, or deliberate poisenning? who monitors american water, and how good a job are they doing? the issues raised by the death led to broader questions and forced people to consider a resource nay had
