Over the past year, our lab has been compiling the arsenic results from drinking water samples that we've received from wells in the Brainerd Lakes Area. The results have shown some interesting trends with arsenic popping up in high concentrations in several areas including Brainerd, Baxter, Nisswa, Breezy Point, and Merrifield. Overall, we found that 10% of wells tested contained arsenic levels over the federal drinking water standard of 10.0 parts per billion.
A drinking water study completed with the Pelican Lakes Association also found that in the Pelican Lake area, wells that are completed just below a clay layer at least 10 feet thick can have higher levels of arsenic than other wells.
