Microorganisms In Milwaukee Rivers, Joseph Gergerich, Forest Stearns

Field Station Bulletins

Fecal coliform bacteria have long been used as indicators of water pollution (Standard Methods, 1976). However, factors that influence the coliform population in natural water bodies may alter the relationships between the coliform bacteria and fecal pollution and hence the usefulness of the organisims as indicators. This study examined the volunteer, non-native vegetation of urban Racine. Various sites were examined, some stable, others subject to continuous disturbance; plant communities were characterized and compared.
