Informing ASR Treatment Practices in a Florida Aquifer through a Human Health Risk Approach

Aquifer storage and recovery (ASR) can augment water supplies hydrologic flows under varying climatic conditions. However, imposing drinking regulations on ASR practices, including pre-treatment before injection into the aquifer, remains arguable. Microbial inactivation data—Escherichia coli, Pseudomonas aeruginosa, poliovirus type 1 Cryptosporidium parvum—were used in a human health risk assessment to identify how time of recharged Floridan enhances pathogen inactivation, thereby mitigating risks associated with ingestion. We quantitative microbial evaluate for gastrointestinal infection (GI) disability-adjusted life years (DALYs) per person year. The developing GI no longer exceeded suggested annual threshold (1 × 10−4) by days 31, 1, 52 80 each pathogen, respectively. DALYs year World Health Organization 10−6) 27, <1, 43 72. In summary, aquifer yields significant reduction risk. findings emphasize that considering caused geochemical conditions within zones, is critical recharge treatment processes.
