Ok so the first batch I ran the rinse was clear after filtering. This time is very different. After filtering the left over "mostly water" is a blue green. What metals could exist in mostly water.
History - Processed 50-60 pounds of high end AV connectors in sulfuric cell. First was the sludge that came from the cell. Rinsed, filtered dissolved in hcl and bleach... result normal.
2nd batch History - after the items were processed I just thru them all in a pail to be rinsed at a later date. That date was today. about 2 - 3 weeks after original processing. After I rinsed them all down with tap water (to rinse residual gold out of crevasses and so on) and filtered the water was an interesting blueish green color... I am baffled? What could be insolution this time that was not last time?
