KENS 5 news reports that a new investigator is looking into the sewage spill that forced a Leon Springs restaurant to close.

The Texas Commission on Environmental Quality has taken over the investigation into how sewage found its way into the water well that supplies Fralo’s Art of Pizza.

At first, SAWS officials said no one was affected by the Aug. 19 overflow, but then 24 restaurant customers were sickened from E. coli.

Health department inspectors allowed Fralo’s to re-open this past weekend after water tests came back negative.

It’s still a mystery how the sewage got into the well.
