Details: SUMMARY: Filter Material Recommendations DETAILS: The City of St Paul owns and operates a water system which supplies approximately 400 people through 153 connections. The City has a groundwater sourced system with 1 permanent well and 1 emergency well and a pressure filter plant for iron and manganese removal. The Circuit Rider was contacted by Lee Koch due to poor filter performance with the removal of manganese. The filter media is near the end of its useful life. In addition, the wells have been experiencing significant sanding, which is likely interfering with the media performance. Previously provided recommendations regarding operations of the filters. Based on raw water quality, made preliminary recommendations regarding treatment plant media replacement. Also, recommended that the City investigate other treatment types, based on the high TOC and manganese levels found in the source water. ACTION NEEDED: Meet with city staff to formulate strategy for moving forward with treatment improvements.
