The City of Atlanta performed several lab studies which led to a successful field trial. Previous treatment of zinc ortho phosphate left the distribution system clogged with corrosion tubercles and higher than desired lead / copper results. The studies using SeaQuest showed:
- A 94% reduction in standing pipe loop lead release
- A 60% reduction in standing pipe loop copper release
- A 56% reduction in mild steel corrosion coupon rates
- A complete cleanout of several sections of distribution pipe with no impact on water clarity
The results were achieved without the addition of lime or caustic to boost the natural pH.
