Water testing kits

You can now pick up water sample kits at our office in Two Harbors to test your water. Collect your sample and then return it to our office the same day before 11 am and it will be sent out to RMB Environmental Laboratories. Results are typically sent within 2-3 business days. Tests include lead, arsenic, nitrates, and coliform bacteria, and cost between $12 and $27 per test.
