I fully addressed your question, you just didn't want to hear the answer because it disagrees with your worldview.
The bottom line is, in the worst pipeline burst in American history, the oil only traveled about
40 miles downstream, according to NOAA figures:

Meanwhile, Standing Rock's new water supply is
75 miles downstream from the pipeline. Considering that the oil would have to travel 35 more miles than it did in the single worst pipeline burst this country has ever seen in order to reach the Mobridge facility, and considering that pipelines are less accident-prone to begin with than other methods of transporting oil, how likely do you think it is that this pipeline will a.) burst and b.) poison their drinking water? I would say it's not very likely.
Your other questions are simply moving the goalposts. You know full well that you're wrong on this, so you want to declare victory and quickly change the subject. At this point, you're just Gish Galloping. And you have the nerve to call others "intellectually dishonest."
