I wonder why there isn't similar protests to remove the existing (and quite old) hundreds (maybe over a thousand) miles of various pipelines running over the same aquifer. I would be much more comfortable with a brand new pipeline built with the latest and greatest materials, tech, and engineering versus one that is a few decades old.
IF the pipeline companies took proper care of their pipelines...IF they performed the appropriate maintenance, and IF quality control was all it's supposed to be...then maybe you'd be right.
BUT, these companies do the bare minimum to take care of their pipelines all over the country. Material specs are cheated when possible, maintenance is an absolute joke...then throw Mother Nature into the mix, and you have the makings of a deadly accident and/or environmental disaster.
Just a few small examples:

ExxonMobil spokeswoman Pam Malek said the pipe leaked an estimated 750 to 1,000 barrels of oil for about a half-hour before it was shut down. Other Exxon officials had estimated up to 42,000 gallons of crude oil escaped.
In all, a relatively small amount of oil...but in an area that's nearly unspoiled...

This rupture of a natural gas pipeline in a residential area killed 8 people and torched 38 homes. Why? Because PG&E scrimped on maintenance, used sub-standard pipe, didn't maintain the proper gas line pressures, and the welds weren't properly inspected. Further inspection of PG&E system pipelines have revealed that many other pipelines in the state are in bad condition.

The Prudhoe Bay oil spill (2006 Alaskan oil spill) was an oil spill that was discovered on March 2, 2006 at a pipeline owned by BP Exploration, Alaska (BPXA) in western Prudhoe Bay, Alaska. Initial estimates said that up to 267,000 US gallons (6,400 bbl) were spilled over 1.9 acres (7,700 m2), making it the largest oil spill on Alaska's north slope to date.[1]
The cause? Lack of maintenance:
One of the reasons for the pipeline failure was an insufficient level of corrosion inhibitor, a liquid which resists corrosion of pipeline by the corroding liquid, which is water.[10] John Dingell read from an internal BP email that said budgetary constraints would force the end of a programme to inject corrosion inhibitor directly into the pipeline system.[9] The process of injecting corrosion inhibitor directly into a pipeline, though costly, is much more effective than injecting in a process plant.
Does the USA NEED oil and natural gas? You betcha we do...but we need it produced in a safe, (relatively) environmentally clean manner. Oil and gas exploration has always been a dirty business. Not much is going to change that process, but the wastes can be better managed, pipelines can be built to much better standards, and they can be maintained to much higher standards.
I worked a few large pipeline jobs. The contractors cut corners everywhere they possibly can. Whether it's in x-raying welds, proper pipe coatings, ensuring that the pipelines are properly bedded to prevent nicks and cuts in the coatings, (to prevent external corrosion) or in how the pipe is handled...they all do whatever they can to save a few bucks here and there.
