(Raymond, MN) — A state agency is telling the Burlington Northern Santa Fe railroad to track groundwater contamination following a derailment earlier this year in Minnesota. The state’s Pollution Control Agency found benzene in groundwater in Raymond after 23 B-N-S-F tanker cars derailed there in March. A spokesperson for the agency tells KSTP-TV that there is no risk to the community because the contaminated water is not being used. But there is some concern locally because the M-P-C-A didn’t notify officials in Raymond about the benzene. The railroad will monitor the extent of the contamination to determine if there is a risk that the benzene could reach a nearby creek.
