Two environmental groups say if an Indiana aluminum smelter doesnt clean up its act theyll sue. The Sierra Club and the Environmental Integrity Project announced their intent to sue the Alcoa Warrick smelter for water pollution violations on Tuesday.

Every five years, the EPA is supposed to review new pollution control technology and set stricter limits for pollutants as those treatments improve. But the standards for facilities like BP's Whiting Refinery in northwest Indiana havent been updated since the '80s.

Workers on the barge were transferring fuel from a cargo tank to another fuel tank. The tank was overfilled and up to 800 gallons of fuel spilled into Burns Harbor.

Extreme water levels and stronger storms are not only threatening homes and beaches along Lake Michigan they could also send toxic waste into communities and the lake.

PFOS and PFOA are two types of the group of industrial chemicals called PFAS. PFAS have been linked to cancer, problems with the immune system, and developmental issues in children.

The EPA wants to inject the groundwater in and around the site with material that will make the harmful chemicals in the water less toxic.

The site of the old Cities Service Refinery now houses a CITGO oil storage facility and vacant property owned by Oxy USA. The EPA found groundwater in the center of the site had high levels of fuel chemicals like benzene, which can cause blood cancers.

Indiana has the most polluted rivers and streams of any state. That’s according to a new report by the Environmental Integrity Project.
