Abstract
Objectives:
Although wastewater monitoring for virus detection has increased in communities worldwide, public awareness, understanding, questions, and concerns about wastewater monitoring are largely unknown. We assessed awareness, knowledge, and support for wastewater monitoring for detection of viruses and bacteria among US residents and elicited questions and concerns from residents about its use.
Methods:
We conducted a survey among a racially and ethnically diverse sample of residents in Colorado, Maryland, Missouri, Nebraska, and Texas to assess awareness, knowledge, and support of wastewater monitoring. We also asked an open-ended question to elicit further questions and concerns from survey participants about wastewater monitoring. Two independent reviewers coded the responses to the open-ended question.
Results:
Among 516 survey participants (52% White, 31% Black, 27% Hispanic ethnicity), 289 (56%) were aware that local public health departments and federal health agencies tested sewer water yet 334 (65%) knew “little or nothing” about wastewater monitoring. After participants were exposed to a brief description of the wastewater monitoring process, 80% “supported” or “strongly supported” wastewater monitoring to detect viruses and bacteria. When we analyzed responses to the open-ended question on wastewater monitoring, 3 broad categories and 9 subcategories of questions and concerns about wastewater monitoring emerged: (1) how wastewater monitoring works (mechanics, accuracy, cost, safety), (2) what is done with the findings generated by wastewater monitoring (public accessibility, government trust, public health response), and (3) what protections were in place against misuse of findings (privacy, fairness).
Conclusions:
Proactive public education is needed to increase understanding, build support, and prevent disinformation about wastewater monitoring. Local systems are needed to share findings rapidly, clearly, and simply.
