To sample or not to sample: A governance-focused decision tree for wastewater service providers considering participation in wastewater-based epidemiology (WBE) in support of public health programs

Wastewater-based epidemiology (WBE) provides value to public health monitoring and protection. Participation of public and private wastewater system operators in WBE efforts is critical to public health surveillance program success and sustainability. However, given the number of WBE solicitations wastewater service providers receive, the limitation of service provider resources, the concerns around privacy, ethics, and equity, and the fatigue associated with responding to COVID-19, operators are becoming more hesitant to participate in WBE efforts. While various ethical concerns and sustainability challenges associated with WBE have been documented, no efforts to date have investigated what factors should systematically influence the decision to provide samples to a WBE effort. Therefore, this study develops a decision-making tool for WBE teams to proactively monitor, manage, and avoid wastewater system operators' operational risks and potential liabilities. Ultimately, using this tool allows WBE program partners in academia, government, and industry to better understand wastewater system operators' needs and challenges surrounding data quality and use, public health ethics, and daily wastewater infrastructure operation.

Evaluation of Preparedness and Recovery Needs of Private Well Users After the Great Louisiana Flood of 2016

CONTEXT

The August 2016 Louisiana flood marked the second 500-year flood in the state in 1 year.

OBJECTIVE

The aim of this study was to identify private well user needs in the aftermath of the flood and to develop disaster planning and recovery recommendations for flood-prone well-reliant communities.

DESIGN

A descriptive cross-sectional study was conducted to collect information from a convenience sample of flood-impacted well users via surveys and water sampling kits, which were distributed to well users 9 to 11 weeks after floodwaters receded (n = 106).

SETTING

Surveys and kits were distributed at roadside flood response and recovery stations set up by local churches in French Settlement, Livingston Parish, Louisiana, an area at the epicenter of the flood-impacted area.

PARTICIPANTS

Subjects were included if they self-reported having a flood-impacted well.

MAIN OUTCOME MEASURES

Surveys collected information to characterize knowledge gaps, risk perceptions, flood impacts, resource accessibility, and well maintenance barriers. Well water tests evaluated total coliform and Escherichia coli.

RESULTS

Among those in low-risk flood zones (n = 22), 27% were in areas designated as having flooded. Among flood-impacted wells that were shock chlorinated after the flood (n = 16), 31.3% tested positive for total coliform and 12.5% for E coli. Only 26% of respondents received well-related information after the disaster.

CONCLUSIONS

Results highlight critical needs for disaster planning and well user education in flood-prone areas, changes to flood risk maps, and concerns with the efficacy of disinfection strategies. Information and resources needs for flood-impacted well users are presented and recommendations on how to improve flood preparedness and recovery are made.

Implications of SARS-CoV-2 on current and future operation and management of wastewater systems

While researchers have acknowledged the potential role of environmental scientists, engineers, and industrial hygienists during this pandemic, the role of the water utility professional is often overlooked. The wastewater sector is critical to public health protection and employs collection and treatment system workers who perform tasks with high potential for exposures to biological agents. While various technical guidances and reports have initially provided direction to the water sector, the rapidly growing body of research publications necessitates the constant review of these papers and data synthesis. This paper presents the latest findings and highlights their implications from a water and wastewater utility operation and management perspective. PRACTITIONER POINTS: Extrapolation from SARS-CoV-1 and MERS-CoV, as well as other surrogates, has helped predicting SARS-CoV-2 behavior and risk management. Data from treated wastewater effluent suggest that current processes are sufficient for SARS-CoV-2 control. Scientific evidence supports the possibility of fecal-oral transmission for SARS-CoV-2. Limited evidence supports the potential survival of infective SARS-CoV-2 on surfaces and in aerosols and the efficacy of control measures at reducing transmission. Protective practices and PPE can protect workers from SARS-CoV-2 and other pathogens found in wastewater.

Panic in the Streets-Pandemic and Protests: A Manifestation of a Failure to Achieve Democratic Ideals

America is at a critical crossroads in history as the COVID-19 pandemic expands. We argue that the failure to respond effectively to the pandemic stems from the nation's protracted divergence from the democratic ideals, we purport to value. Structural racism and class-based political and economic inequity are sustained through the failings of the nation's democratic institutions and processes. The situation has, in turn, fostered further inequity and undermined science, facts, and evidence in the name of economic and political interests, which in turn has encouraged the spread of the pandemic, exacerbated health disparities, and escalated citizen tensions. We present a broad vision of reforms needed to achieve democratic ideals which we believe is the most important first step to achieving true political representation, achieving a resilient and sustainable economy, and fostering the health of vulnerable communities, workers, and the planet.
