Once water quality standards are approved, states are tasked with monitoring their surface waters to determine where impairments occur, and watershed plans called Total Maximum Daily Loads (TMDLs) are developed to direct water quality improvement efforts including changes to allowable bacteria loading by point sources and recommendations for changes to practices that reduce nonpoint-source contributions to bacteria loads.

Of specific interest are the red regions of the middle column, indicative of purple non-sulfur bacteria (e.g. ''Rhodospirillaceae | PH indicator | Myers-Briggs Type Indicator | Indicator value | Indicator | gram-positive bacteria | Economic indicator | ''E. coli'' bacteria | Coliform bacteria | Bomb Power Indicator |
