The boil water advisory has been lifted but another E-coli contamination is still possible that's what City Manager Ron Olson told the city council Tuesday afternoon.
As Action 10 News first reported the E-coli contamination that led to our recent advisory came from Flour Bluff likely from a homeowner who's violating city ordinance.
The problem is the city doesn't know who, meaning another contamination could happen but the city is working on a possible solution.
The water department says the contamination came from a sprinkler system or water well that's improperly connected to the main system.
There are 126 registered wells in Flour Bluff and most of them don't have backflow preventers, a device the keeps that water from entering the public supply.
Not having a backflow preventer violates a city ordinance.
It would take time to figure which wells are improperly connected, so the city is considering a mass installment of prevention devices on the service lines of every home that has a well.
It's unclear if homeowners will have to pay for these installations.
Ron Olson the City Manager of Corpus Christi said "We need to protect the public water system first. We need to worry about enforcement after we have that under control."
Addressing the water wells would just be a start.
There's also tons of sprinkler systems without backflow preventers in homes that don't have water wells and those need to be fixed.
