Thank you for the link -- that is pretty wild.<p>&#x27;So the Virginia Tech researchers took 30 different readings at various flow levels. What they found shocked them: The lowest reading they obtained was around 200 ppb, already ridiculously high. But more than half of the readings came in at more than 1,000 ppb. Some came in above 5,000 -- the level at which EPA considers the water to be &quot;toxic waste.&quot;&#x27;
