Blue Earth County discontinued in-house water testing in 2010. As a convenience to residents, Blue Earth County worked out an arrangement with Minnesota Valley Testing Laboratories (MVTL) to provide these water testing services. MVTL water test kits can be picked up in the Property & Environmental Resources Department at 410 S. 5th Street, 2nd Floor, Monday-Friday, 8:00 am to 5:00 pm. However, Monday is the only day of the week that samples can be dropped off for pickup and testing by MVTL. For other testing options, refer to the Yellow Pages, under Laboratories-Testing, or go to the MN Department of Health website for a list of Accredited Laboratories.
