Andy,

This is the stuff I think we tried using and Jason said did nothing. We may want to revisit this after we remove biosolids this summer. We should take a sludge judge reading after removal and introduce this stuff and then do another judge prior to next year’s removal to see if we have any impact.

Regards,
