Goals of Phase I Data Analysis Gather available data Analyze existing data Potential source inventory Identify data gaps Develop monitoring plan

E. coli standard Water quality standard changed in 2008 from fecal coliform to E. coli E. coli standard : Not to exceed 126 organisms per 100 milliliters as a geometric mean of not less than five samples representative of conditions within any calendar month, nor shall more than ten percent of all samples taken during any calendar month individually exceed 1,260 organisms per 100 milliliters. The standard applies only between April 1 and October 31.

Gather Available Data, 1999-2008 Water Quality Data Flow Data Initial data request Initial data gathering • MPCA (STORET), • USGS, MetCouncil (WOMP) MetCouncil, USGS, MDH, Data request MDA, water utilities • Watershed organizations, Follow-up request counties, municipalities, and • Watershed organizations, townships counties, municipalities, and townships
