ST. HELENA (KCBS) – Thousands of gallons of a chemical used as a disinfectant spilled onto the ground at a water treatment plant in St. Helena Saturday afternoon.

CalFire Captain Tom Knecht said that the leak was reported at about 4:20 p.m. at the plant on Sage Canyon Road.

“Approximately 11,000 gallons of sodium hypochlorite escaped its tank into its secondary containment field,” said Knecht. “The chemical started leaking through the secondary containment field at a rate of around five gallons a minute. Our fire department hazmat team responded and they diked off the leak from the secondary containment, that was spilling onto the ground.”

Knecht said there were no injuries and no danger to the public from the spill and crews were able to pump the chemical into portable storage tanks.

The chemical is essentially a strong bleach. Officials said it did not enter either Lake Hennessey or Conn Creek, which are both nearby.

The water treatment plant is owned by the city of Napa.

Officials are still investigating what caused the leak.

    Really. They should have said ,”11,000 gallons of chlorine(used to treat and disinfect ground water” have spilled. Instead they hype it up, sodium hypchlorate, aka bleach, aka chlorine.

    The FBI and DEA fabricate evidence, steal from suspects and use murder to close those bad cases.
    How is it that 12 of the 9/11 terrorists could live for 2 weeks just 2 miles from NSA head quarters in Maryland.
    This after several of them had taken flight simulator lessons on Jumbo jet trainers and several of them where on State department terror watch lists.
    There is evidence that employees from DoD, CIA and DOJ accepted bribes from Al Quida.
    If DoJ and DoD employees where more concerned with doing their jobs than enriching themselves by stealing from suspects and taking bribes, then there might have been more a chance that 9/11 had never happened.

    With very long term harassment the FBI and DEA are intentionally creating their own terrorists and criminals when evidence of any supposed crime does not support their investigation/harassment of a suspect.
