DRAFT 8-17-07 Table 1 Well Water Iron and Manganese Data In order to minimize customer complaints and improve aesthetic quality of water supplied to customers, many communities in our region install and operate water treatment plants which remove the iron and manganese from their ground water supply. Although the City of Lino Lakes currently is in compliance with the Primary Drinking Water Regulations, the construction of a Water Treatment Plant would allow the City to supply finished water which meets both the Primary and Secondary Drinking Water Regulations. The current level of water quality complaints is not perceived as sufficient in numbers to justify water treatment at this time. As the customer base continues to expand, the City should expect the number of water quality complaints to increase. The City should also anticipate and be prepared to provide water treatment to remove iron and manganese as the customer base expands and the water system financial capabilities increase. Water treatment will improve consumer satisfaction with the City's water supply.
