From the Cañon City Daily Record (Rachel Alexander):
“As you are aware, the pool of water in the impoundment has diminished by evaporation to the extent that only the addition of base material has maintained the pool and consequently the head,” [Radiation Safety Officer Jim Cain] said in the letter. “In addition, introduction of base material to the pool has become inefficient and we have no means to improve the delivery.”
Steve Tarlton, of CDPHE, said the pH monitoring was necessary when the pond was in active use, but it is no longer operating. “Since they started dewatering the ponds, maintaining the pH is not critical,” he said. “The pH issue has gone away. We don’t want them to add water to the pond if they don’t have to. It makes sense to stop monitoring.”
CDPHE officials are looking at the monitoring issue in conjunction with the company’s dewatering plan and they expect to make a decision in the next few weeks.
