What are the current plans in place to address the problem?

By far the most effective way to address this contamination problem is to construct a community-wide sewer system and stop disposing human sewage into the ground above the contaminated aquifer.

Without a plan for a sewer system, MPH staff would be required to revise the regulations in the SMA in a way that will continually decrease nitrate levels until the monitoring wells show concentrations at or near what staff see in any other area of Missoula County.

While a sewer system may result in a monthly charge to residents, it will be much more affordable than each property owner having to pay thousands of dollars to upgrade their individual septic system. Depending on the location and required level of nitrate treatment, septic system modifications and installations easily cover the range of $10,000 to $80,000. MPH is very aware this is not financially reasonable for residents, which makes a sewer system even more critical.

MPH is working with the Sewer District and community to find a solution to this problem. Staff want to fully understand the community’s characteristics and concerns and have spent a significant amount of time reaching out to a diverse group of potential stakeholders. Staff hope our outreach efforts result in a strong group of partners who can assist and share expertise. We all have a clear, common goal: ensuring Seeley Lake residents live in a safe and healthy environment, and that the natural resources in this area are protected.
