600 Town Center Parkway – Lino Lakes, MN 55014-1189 <br />City Hall: 651-982-2400 – www.ci.lino-lakes.mn.us <br /> <br />Dear Residents, <br /> <br />Every Lino Lakes resident is receiving this letter to notify users of a consumption advisory regarding the municipal <br />water supply. This notice affects approximately 5,000 households and businesses that currently use the municipal <br />water supply. In addition, the nearly 1,500 properties with private wells may be affected. <br /> <br />The City is dedicated to providing clean and safe drinking water to residents. Testing by the Minnesota <br />Department of Health (MDH) shows the City’s municipal water supply continues to meet all Safe Drinking Water <br />Act standards. <br /> <br />MDH conducted additional testing in 2019 as part of a study of unregulated contaminants. This testing showed <br />that some of our wells have manganese levels above MDH’s recommended health guidelines. <br /> <br />The Issue: Manganese <br />Manganese is a naturally occurring element found in rocks and soil and is often found in Minnesota ground and <br />surface water. Your body needs some manganese to stay healthy, but too much can be harmful. Learn more by <br />visiting the MDH webpage at www.health.state.mn.us and searching for Manganese in Drinking Water. <br /> <br />Manganese is unregulated and does not have an enforceable standard. However, the MDH recommended health <br />guidelines are: <br /> <br />1) If you have an infant who drinks tap water or drinks formula made with tap water, a safe level of <br />manganese in your water is 100 parts per billion (ppb) or less. <br /> <br />2) If you have an infant who never drinks tap water or formula made with tap water, a safe level of <br />manganese in your water is 300 ppb or less. <br /> <br />3) If everyone is more than one year old, a safe level of manganese in your water is 300 ppb or less. <br /> <br />The City requested testing from MDH to better understand manganese levels for all City wells. The most recent <br />results are as follows: <br />Well #1 158 ppb Well #4 84 ppb <br />Well #2 527 ppb Well #5 143 ppb <br />Well #3 322 ppb Well #6 408 ppb <br /> <br />The City’s municipal water supply is a mixture of water from all six wells. The water mixes in water mains and <br />towers, and then travels to customers’ taps. The City cannot know the level of manganese at any given drinking <br />water tap. <br /> <br /> <br />(OVER) <br /> <br />
