Partially treated or untreated wastewater caused or contributed to a fish kill in the Pearl River Saturday resulting in the death of several thousand fish, according to a press release from the state Department of Environmental Quality.

Biologists with the state Department of Wildlife and Fisheries investigated the report and surveyed 45 miles of the river from Richardson Landing to the entrance of the West Pearl River Navigation Canal, according to the release.

The fish found dead included paddlefish, American eels, catfish and shad.

DEQ took water samples that have been sent to a laboratory for study. Results from those tests should be available in four to five days, according to the release.

According to the state Department of Health and Hospitals, there is no impact on drinking water from community water systems since none of them use water from the river.

DHH is telling people they should not come in contact with discolored water in the river, and they should never collect dead or floating fish to eat.

Crews with the state Department of Wildlife and Fisheries, U.S. Fish and Wildlife Service and DEQ are continuing to survey the river on Monday.
