Every three years the Grand Marais Public Utilities Commission (PUC) examines 10 houses to see if the water is within safe consumption levels for lead and copper as required by the State of Minnesota and Environmental Protection Agency (EPA).
“All of the samples were satisfactory,” said Water/Sewer Plant Manager Tom Nelson, following the completed testing.
Nelson gave his report to the PUC on Wednesday, September 21.
Lead is especially troublesome when it is found in drinking water. According to the EPA, the standard for acceptable lead levels in drinking water is 20 parts per billion. In children that have nutritional deficiencies (iron, calcium, zinc) shortcomings in these minerals encourage lead absorption. This shortage can impact the central nervous system because lead mimics calcium, which is essential in neurotransmission in the nervous system. And this, according to the EPA, can lead to havoc, causing the brain cells to misconnect with one another.
According to the EPA, when lead enters a water system, it is most often from lead solder used on chrome or brass-plated brass fixtures or faucets. If you have old valves, it might be a good idea to purchase a test kit or ask to have the city come and test your water.
Jason Edens of Minnesota Rural Renewable Energy Alliance visited the city’s water plant on Friday, October 7. He was there to assess whether or not a photovoltaic (solar electric system) could be installed on the roof of the plant and if that was practical, how much energy could this system generate and how much would the solar panels cost to purchase and install. He will get back to the PUC at the board’s next meeting.
