Bill > S00149

This bill requires the New York State Department of Health and Department of Environmental Conservation to establish a maximum contaminant level of 0.35 parts per billion (ppb) for 1,4-Dioxane, a synthetic industrial chemical, in various water sources. Specifically, the Department of Health will set this standard for potable (drinking) water supplies, while the Department of Environmental Conservation will set the same standard for ground water and runoff water from wastewater and water supply treatment plants. The bill mandates that these standards be implemented as quickly as possible, potentially through emergency rules if the commissioners determine such action is necessary to protect public health. 1,4-Dioxane is a potentially harmful chemical used in industrial processes that has raised environmental and health concerns due to its potential carcinogenic properties and persistence in water systems. The bill aims to establish a uniform, low-level standard to minimize public exposure to this contaminant across different types of water sources in New York State.
