The Town of Bernalillo began injecting ferric chloride, an iron compound, into its water supply Thursday at two troubled arsenic treatment facilities, Mayor Jack Torres announced Thursday evening.
It is the Town’s latest attempt to bring arsenic levels down to federal and state drinking water standards, Torres said.
The effects of the iron treatments in combination with the Town’s existing aluminum-based treatment system will be tested for 24 days.
After 24 days, water quality lab reports will be analyzed to decide whether to use both iron and aluminum treatments, or to scrap the aluminum-based system entirely, according to a Town press release and a Corrective Action Plan prepared by the Town’s new water system engineering firm, Wilson & Company.
Former project engineer Ramesh Narasimhan operated the Town’s troubled water system between 2008 and 2010 without state approval and in violation of state law, according to the state Environment Department.
Narasimhan was fired by the Town in February.
