WV Utility: 2 Changed Filters Show No Chemical Contamination< < Back to
The water company impacted by a January chemical spill says water treated with two replaced filters shows no chemical contamination.
However, the company still has six or seven weeks-worth of changing 14 other filters found to contain traces of a spilled chemical. The chemical found in treated water late last month was 2,000 times less concentrated than federal health officials deem safe to drink.
West Virginia American Water began replacing filters April 1 after finding trace chemicals were flowing off them into the distribution system for 300,000 people.
The company has said previous tests couldn't detect the chemical at such low concentrations.
The company says new filters will cost more than $1 million.
The Jan. 9 chemical spill at Freedom Industries spurred a tap-water ban for up to 10 days.
