Environmental justice issues are understood to exist and persist throughout the country and across the world; environmental hazards frequently impact poor and minority populations disproportionately more than non-Hispanic Whites (herein referred to as White) and upper income communities. With much of the world urbanizing, increasing numbers of people interact with urban streams. Throughout these interactions, urban streams can impact the health and well-being of surrounding communities. This study addresses a gap in the literature by assessing the quality of natural resources by race and class, where past studies have examined access to green space, activity of anglers, and drinking water quality. The following study contributes to this body of work by investigating if recreational water quality of urban streams, as measured by E. coli levels, is correlated to the composition of surrounding communities. Existing data from local and federal agencies that collect water quality data, as well as data from the U.S. Census Bureau, is utilized to determine if those neighborhoods that have proportionately larger minority and low-income populations are associated with lower overall water quality for four cities. Mixed effect multilevel linear regression models suggest that those who rent are most potentially exposed, with an average increase of 0.00655 MPN/100mL / CFU/100mL in average log transformed E. coli for every one percent increase in renters in the combined city models and an average increase of 0.00855 MPN/100mL in average log transformed E. coli for every one percent increase in renters in Austin in models run by city. Occupied housing is also shown to be significant, with an average increase of 0.02300 MPN/100mL / CFU/100mL in average log transformed E. coli for every one percent increase in occupied housing in combined city models. Asian populations showed a negative relationship with E. coli in Austin in by city models, where there is an average decrease of 0.03025 MPN/100mL in average log transformed E. coli for every one percent increase in the Asian population. The Hispanic population is close to significance in two models, showing a positive relationship with E. coli, but is only statistically significant in one by city model in Los Angeles.
