Elkhorn utility officials reported finding elevated levels of arsenic in a water sample from October, but the public is not at immediate risk, according to a Facebook post Monday morning.
In a follow-up post a few hours later, utility officials assured residents that city water currently “meets the federal drinking water standard for all contaminants, including arsenic.”
Residents do not need to use an alternate water supply, such as bottled water, according to the post. If someone has specific health concerns, however, city officials recommend consulting a doctor.
A sample from Oct. 26 showed levels of arsenic above the state’s “maximum contaminant level” in the city’s drinking water.
In their follow-up Facebook post, utility officials clarified that the Oct. 26 sample from Well 9 was representative of water that had not been treated for arsenic. Officials said a state Department of Natural Resources engineer ordered well operators to take the sample knowing that the arsenic removal treatment wasn’t operating.
Elkhorn officials said they would have notified the public immediately if there was an immediate risk.
“Since the results of this testing were reported, the WDNR needs to be transparent with the information and let it follow the regulatory process in the Wisconsin Administrative Code, even though it is not representative of the facility,” the post states.
“January 26, 2019, testing confirms that the water from the entry point of Well 9 ... is compliant with the arsenic standard.”
City officials urged people to share the information with others who drink city water, including those who might not have gotten notices in the mail, such as people in apartments, nursing homes, schools and businesses.
