The Louisiana 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, potentially leading to the formation of carcinogenic byproducts known as trihalomethanes (THMs). These byproducts have been linked to increased cancer risks, particularly bladder cancer, raising concerns about the long-term health implications for Louisiana residents.

The resolution calls for the Department of Health to revise its regulations on chlorine levels to align with current scientific evidence and federal guidelines. It emphasizes the need for consultation with independent scientists, environmental health experts, and local water authorities to develop updated disinfection guidelines that ensure microbial safety while minimizing health risks and economic burdens on local water systems. The resolution aims to address both public health and financial challenges faced by under-resourced water authorities in Louisiana.
