Federal agents have visited a company that cleaned up and hauled chemicals from the site of a spill that contaminated 300,000 West Virginians' water.
U.S. Attorney Booth Goodwin confirmed that FBI investigators were at Diversified Services LLC in St. Albans on Thursday. Goodwin could not comment on why they were there.
Diversified Services received almost $433,000 from Freedom Industries in January, according to court documents. The company had worked for Freedom Industries well before the incident, however.
The spill spurred a water-use ban for days.
Freedom is also nearing a March 15 deadline to start tearing down its tanks at the Charleston site of the spill, per state orders.
Some witnesses, including state environmental inspectors, have already appeared in front of a federal grand jury for the Freedom investigation.
