CORRECTIVE ACTION:

Nineteen cleaning products have been sampled and analyzed for phosphorus. Of these products three have been identified as possible major phosphorus contributors. These products are a)

Power Pac Degreaser b) Husky Bowel cleaner and c) Septin disinfectant. A meeting with Building Maintenance was held on December 4, 1985. The problem relating to cleaning products was discussed. Building Maintenance agreeded to provide a list of all products used and the monthly volumes of each. Building maintenance is to restrict use of the above three products to minimal levels until alternate products can be procurred.

Our Engineering Department is evaluating treatment systems that can reduce the total phosphorus to within permit limitations.

We recognize that a ferric chloride treatment system has been approved by the Department, however, there may be adverse biological reaction with the installation of this type of system.
