SALT LAKE CITY (AP) -- Manmade chemical compounds known as PCBs are showing up in fish at Utah Lake, but it's still unclear where they're coming from.

The Utah Division of Water Quality had hoped to have some answers this fall from a study of the lake's bottom sediments. But the results released Tuesday didn't pinpoint one source.

State officials say levels of PCBs were relatively low in the sediments, meaning they likely aren't a key source for PCBs showing up in fish at the lake.

They say it's possible the PCBs aren't coming from a new source, but are simply being passed from one animal to another in the lake's food chain.

Meanwhile, a fish consumption advisory for catfish and carp caught at Utah Lake remains in effect.
