Lawmakers will wait a month before considering controversial changes to Kentucky’s water quality standard for a substance called selenium.
Selenium occurs naturally in small amounts, but is released in heavier doses by some coal mines and can cause deformities in fish. There are currently two standards for selenium in water: one based on short-term exposure and another for long-term exposure. The proposal from the Kentucky Division of Water would essentially get rid of the first standard, and change the way the second is measured.
