St Bernard Chlorine Monitoring - 2013

Monthly testing in St. Bernard’s water had always detected at least some minimal chlorine levels in recent years, according to DHH and parish documents. But chlorine at certain sites at times dip below 0.5 mg/L, with many sites in Arabi, Violet and Yscloskey regularly hovering right around that dangerous threshold.

The deathly amoeba can survive and thrive in water that has chlorine levels at 0.4 milligrams per liter or below.

Recent tests by DHH found no chlorine at all at the sites where the amoeba was found.
