The House Concurrent Resolution urges the Louisiana Department of Health to conduct a comprehensive review of the health and environmental impacts of chlorine levels in public water systems. It highlights concerns regarding the elevated chlorine concentrations mandated by the department, which were increased in 2013 to address public health issues related to harmful microorganisms. The resolution points out that the current chlorine levels are significantly higher than both previous legal minimums and federal recommendations, and it raises alarms about the potential formation of carcinogenic byproducts, specifically trihalomethanes (THMs), as a result of excessive chlorine use.

The resolution calls for the Department of Health to revise its regulations to align with current scientific evidence and federal guidelines, while also considering the distinct treatment needs of surface and ground water. It emphasizes the importance of consulting with independent scientists, environmental health experts, and local water authorities to develop updated disinfection guidelines that ensure microbial safety without imposing undue health risks or financial burdens on local water systems. A copy of the resolution is to be transmitted to relevant state officials, including the governor and the secretary of the Louisiana Department of Health.
