In my last post, I discussed the solutions that innovative drilling and technology companies are using to reduce water consumption for fracking projects. These technologies are easier to build economies of scale because almost all fracking sites across the country can use similar technologies, once and if it is proven. However, in my research, it was interesting to learn that the wastewater treatment for drilling projects is a much tougher issue to tackle. There is no universal solution to treat drilling wastewater because the geology and chemical makeup of the produced water varies widely across sites and formations. But that has not stopped savvy businesses from creating innovative technologies to address this issue. Continue reading →
