Clark estimated the remediation work would take about one year the company does not yet have a cost estimate. "We were able to contain it so that no more water was leaking," said Christopher Clark, Xcel's president for Minnesota. Once the leak was discovered, Xcel began diverting the water to an in-plant water treatment system - a step that is continuing. "Our goal is to remove the source, the contamination that is down there as much as possible," he said. ![]() Xcel is paying for sampling, pumping and temporary treatment, Koudelka said. Water is being pumped out of wells on site both to remove the contamination and control its underground flow. Xcel and the state are actively managing the site to make sure an underground plume of tritium doesn't begin to drift beyond the property, including to the nearby Mississippi River, said Kirk Koudelka, an assistant commissioner at MPCA. ![]()
