Land use is directly linked to coastal water quality for island communities. Excess nutrients and runoff from agriculture and industry can change coastal microbial communities, introduce wastewater, and promote pathogens and harmful algae. We surveyed microbial communities across a range of impacted watersheds on Tutuila, American Samoa, measured these changes, and identified microbial indicators for impacted watersheds. This work addressed knowledge gaps in tropical island ecology and built upon ties with local and federal managers on Tutuila to better address sources of tainted freshwater to the coast and identify watersheds at greater risk of harmful blooms and reef degradation.
