Arcata Marsh Microbial communities 2020
These samples investigate the relationship between aquatic bacterial diversity and ammonia removal function in a wastewater secondary treatment constructed wetland system. Specifically, we took water samples across a system of 6 interconnected ponds, from August 2019 to February 2020, at the Arcata Wastewater Treatment Facility (AWTF), in Coastal Humboldt County (California, USA). We used 16S rRNA gene amplicon sequencing to measure bacterial diversity and composition, and an ammonia electrode probe to measure ammonia at the influx and efflux positions of each pond.
