NEW ORLEANS (AP) — Louisiana workers are checking records of more than 80 water treatment systems using the same disinfection process as two where a rare but deadly amoeba was found. They want to be sure they are keeping chlorine levels at recommended levels.

But state Sen. J.P. Morrell wants every parish and municipal water system statewide tested now. And he says current rules are too vague. He wants a specific amount of chlorine required.

The amoeba was found in water treated by St. Bernard Parish, where a boy was infected in August, and a DeSoto Parish district where a woman died in 2011.

J.T. Lane, head of Louisiana's public health office, says about 85 Louisiana systems use a mixture of chlorine and ammonia rather than the straight chlorine used in nearly 1,300 others.
