All it takes is someone to dump mercury down the toilet, and I've got this problem again. |
We think that someone, a customer, was disposing of a mercury-containing substance into the system. It has nothing to do with plant's design or operation. |
We took a look at dentists' offices and industrial customers and sampled at strategic locations. It's hard to know exactly where it comes from. We went business to business in certain areas, asked them if they use mercury compounds and told them they can't dispose of it down the sewer. |
