Perhaps they chose not to elaborate and make an overly technical article but I'm curious to know what the alternative method is. With the amount of pollutants and crap that have been created, I don't see any good option.

It seems lose-lose to me. Take time to test samples and develop a "safe" method of pumping water out and it will only deepen the criticisms of being slow to respond. Damn the samples and pump the water and you're an eco-terrorist.
