2 – MPCA Bacterial Impairment Standard: 126 E. coli/100mL (geometric mean of 5 samples in 30 day period); no individual samples greater than 1260 E. coli/100mL
3 – EPA 2012 Recreational Water Quality Criteria – Recommendation 1 (Estimated illness rate = 36/1000)
4 – Based on typical range/value for water reuse programs in other states
5 –Useful for distribution system design, but often used a general indicator parameter, too.
6 – TSS guidance provided by Cathy Tran, DLI
7 – Per Table R.3b.6 in Metropolitan Council Stormwater Reuse Guide
8 – Suggested by Bruce Wilson. Per Table R.3b.5 in Metropolitan Council Stormwater Reuse Guide
9 - Recommendation from Anita Anderson on 12/6/2012 email as temperature impacts bacterial growth
10 –Per Tables R.1a.1 and R.3b.5 in Metropolitan Council Stormwater Reuse Guide
