In Sandy, Utah, a do not drink advisory was lifted for 600 residents previously cautioned not to drink from their kitchen taps. Why?
Elevated levels of copper and lead.
The contamination occurred when supply employees inadvertently released undiluted fluoride into their water system for about two days.. The town authority is facing backlash because of its late notification of residents of the potential contamination quickly.
According to The Deseret News, an investigation into the town’s water quality began Feb. 6 when residents reported a potential problem. The state was then notified Feb. 8. Approximately 150 residents reported possible symptoms from drinking contaminated water. Several dogs fell ill as well. While Sandy officials announced Feb. 15 that the water was safe to drink again, the do not drink advisory was reissued until lab results were able to determine the amount of lead and copper concentrations.
Test results from two homes revealed lead levels 26 times higher than the federal threshold and copper levels 22 times higher, according to Utah Division of Drinking Water Director Marie Owens.
“Unfortunately, I don’t think we’ll ever be able to know exactly what the homes were exposed to during the 44-hour time frame that the fluoride event was happening,” Owens said. “We can’t go back and retroactively sample that.”
While the do not drink advisory was lifted Feb. 17, many residents still have questions regarding the quality of their water. Residents are questioning whether they need to replace their pipes and copper fittings and have asked the town to test their drinking water.
“What condition are my pipes in right now? What condition is my water heater in now that I’m not going to be continually exposed?” said Jodi Monaco, resident. “I just want to know. All of us just want to know.”
To their credit, he town is paying for water tests and asks residents to collect water samples. Sandy has been cited by the Utah Division of Drinking Water for failure to adequately notify the public about potential contamination. The agency must be notified of contamination within 24-hours.
“Once I became aware this was more than just a localized event, which was how it was presented to me originally… it was sort of an all-hands-on-deck approach,” said Mayor Kurt Bradburn. “We put everything out on social media. We activated our emergency protocol so we could literally take people door to door and make sure we spoke to them, gave them water, gave them notice. But the point is, we could have done that sooner. And that’s what I deeply apologize on behalf of all residents that we didn’t do that sooner.”
Ian: So.. is this an isolated incident? Unfortunately, no. Here in Australia we were alerted to high fluoride levels on the Gold Coast some years back when the water authority was implementing their new desalination plant.
The Big Question
The question remains: can an off-the shelf water filter cope with this kind of incident. In our view, it's a no. But there is hope. The UltraStream, (our invention) is an extremely high level performance water filter with a design brief of finding and incorporating the world's best filtration media. It's not just talk. We've tested its fluoride reduction over the life of the filter and received a reading of 97% removal.
