Effects of Corrosion Inhibitors on Antibiotic Resistance in Drinking Water Distribution Systems

Key Takeaways Antibiotic‐resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in environments such as drinking water distribution systems (DWDS) could increase the likelihood of pathogenic antibiotic resistance. A recent study aimed to quantify effects of three corrosion inhibitors on bacterial antibiotic‐ and metal‐resistance abundance in a source water serving several water treatment plants. Study results suggested that corrosion inhibitors such as orthophosphates likely have a significant role in bacterial communities and the prevailing levels of ARB and ARGs in DWDS.
