Impact/Purpose:
Aerobic biotreatment systems can treat multiple reduced inorganic contaminants in groundwater, including ammonia (NH3), arsenic (As), iron (Fe), and manganese (Mn). This study assessed the treatment performance and microbial communities within 7 pilot- and full-scale groundwater biotreatment systems in the United States that treated < 0.03-3.79 mg NH3-N/L, < 4-31 µg As/L, < 0.01-9.37 mg Fe/L, and 2-1220 µg Mn/L with different reactor configurations. Influent NH3, Fe, Mn, and total organic carbon concentrations differentiated the biofilters to a similar magnitude, but influent NH3 had the greatest effect on the microbial communities. Aerobic groundwater biofilters are complex, and improved understanding could lead to engineering enhancements. This study may be of interest to engineers and scientists involved in drinking water treatment and biological treatment processes.
