The current arsenic level of the raw water at your system is 29 itg/L. The maximum contaminant level (MCL) as stated in the SDWA is 10.4 µg/L.

On August 16, 2007 three separate emails were received from Michael Kuruvilla outlining possible corrective actions, including a forwarded email from Ron Moorse, Wayzata city administrator, stating that city water is to be available to the Montessori school property by fall of 2007. MDH accepts this email as sufficient documentation that city water hook up will be available in the near future. We accept the connection to the City of Orono water supply as your plan of action provided the following conditions are met: 1. Continue to post public notice as outlined in the April 25, 2007 NOV at all potential drinking water taps. The public notice certification form has not yet been received by MDH office; please submit that form as soon as possible. If you do not have the copy of this form (enclosed in the original NOV) please contact me for a replacement copy. As part of the public notice requirements we are asking that a letter explaining the water quality issue be sent to each parent. We have attached a draft copy of a letter that can be used. 2. As an interim measure, continue supplying purchased bottled water as outlined in the April 25, 2007 NOV. Receipts must be kept, and made available for review by DWP. 3. It is understood that the connection to city water will take place before December 31, 2007. DWP must be notified if connection to city water is delayed beyond this date. 4. Plan and specification covering the water service line to be installed is to be submitted to the Department of Labor and Industry prior to the any construction.
