Details:	SUMMARY: Filter Operations Troubleshooting 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. Met with City Staff (Lee Koch and Frank Sinclair) regarding recent efforts made to increase filter performance. Reviewed operational procedures. Discussed need for filter media replacement, including the need to determine the optimum media for the city’s source water. Provided Mr. Koch with a list of water quality parameters for which to test to assist in determining the best filter media. ACTION NEEDED: Follow up with operational and media recommendations.
