Air and water quality continue to be concerns at Mammoth Cave National Park.
Two years ago... National Environmental Groups listed the park as one of the country's most five polluted.
Park Officials say coal-fired power plants and other industrial development has contributed to the problem.
Mammoth Cave's Park Superintendent says he must look beyond the park's boarders to protect it.
Staff often discuss air and water quality issues with developers and local government officials.
