A Batesburg-Leesville man received a sentence of house arrest, five years on probation and a large fine after pleading guilty to violating the federal Clean Water Act.
John Ashley Mabus, 44, was sentenced Thursday after making the plea in May.
His company, Mabus Construction Co. Inc., was digging a ditch for a sewer line in January 2008 near the Clearwater Finishing Industrial Facility, an abandoned textile mill in North Augusta. When water from a lagoon contaminated with heavy metals began leaking into the ditch, Mabus directed employees to pump about 4 million gallons of water and sludge into Little Horse Creek over three days in order to continue work on the ditch.
Little Horse Creek is a tributary of the Savannah River.
Mabus was ordered to eight months of house arrest and five years of probation, served concurrently, and he must pay a $7,500 fine.
