“…Three exposure scenarios were modeled based on common exposure pathways of nonpotable uses of reclaimed water , and pathogens of concern for these applications . Toilet flushing, consumption of lettuce irrigated with recycled wastewater, and accidental ingestion of water used for ground irrigation (i.e., golf courses and public parks) were chosen as exposure scenarios.…”

“…7,15 A quantitative microbial risk assessment (QMRA) would not only provide insights of the magnitude of the risk but also offer guidance for policy decision-making to establish water quality criteria for water reuse in light of the AR risks. 16,17 Through the steps of hazard identification, exposure assessment, dose−response assessment, and risk characterization, the likelihood of risk (i.e., infection, illness, or death) can be quantified and better understood. Previously established dose− response models or exposure scenarios are helpful in this framework, especially when paired with a collection of pathogen concentration data for specific locations or water fixtures.…”

Antibiotic-resistant bacteria (ARB) have become a major threat to public health and modern medicine. A simple death kinetics-based dose−response model (SD-DRM) was incorporated into a quantitative microbial risk assessment (QMRA) to assess the risks of exposure to reclaimed wastewater harboring antibiotic-resistant E. coli, Legionella pneumophila, and Mycobacterium avium for multiple exposure scenarios. The fractions of ARB and trace antibiotics present in the body were incorporated to demonstrate their impact on infection risks. Both ARB and antibiotic susceptible bacteria, ASB, are assumed to have the same dose−response in the absence of antibiotics but behave differently in the presence of residual antibiotics in the body. Annual risk of L. pneumophila infection exceeded the EPA 10 −4 pppy (per person per year) benchmark at concentrations in reclaimed water greater than 10 3 −10 4 CFU/L, depending on parameter variation. Enteropathogenic E. coli infection risks meet the EPA annual benchmark at concentrations around 10 5 −10 6 total E. coli. The results illustrated that an increase in residual antibiotics from 0 to 40% of the minimum inhibitory concentration (MIC) reduced the risk by about 1 order of magnitude for E. coli but was more likely to result in an untreatable infection.

“…Surface water in watercourses is exposed to pollution by humans, industry, agriculture, transport and the like [1,2]. Water quality is becoming a criterion and its assessment is a requirement for the determination of the water source for different areas of the economy and for households [3,4]; thus, the continuous monitoring of processes leads to the elimination of pollution of surface and groundwater [5,6] and a need for reliable and sustainable water management [7,8]. Recently the water management approach has changed because of intensive climate changes [9][10][11].…”

The sustainable management of river basins is a comprehensive problem involving not only environmental quality but also socio-economic aspects. The primary objective of the study is to propose a sustainable management model of a river basin based on a clear identification of the good water quality in the river basin applicable for any river basin. The proposal is based on a monitoring of the quality of surface water in the basin, a quantitative and qualitative analysis of pollution, a questionnaire survey on the sewer systems and wastewater treatment in the basin and the diffuse sources of water pollution. For a better outline, a case study of Hornád river basin, Slovakia, was carried out. Two methodologies were applied: SWOT analysis for identification of indicators and the priorities and AHP analysis for a prioritization of the decisions. These analyses can be carried out for any activity based on identification of indicators and the priorities of the defined indicators to promote sustainable development. Based on the findings and the results of the analyses the model for managing the development of surface water quality in the basin was proposed. Generally applicable principles of sustainable development, accepting legislation in the field of water management, considering the quality of surface water in the basin, the impacts of wastewater discharges into the recipient, the identification and evaluation of positive and negative aspects of surface water quality, and the implementation of the proposed measures and post-implementation monitoring of qualitative development were covered in and by the proposed model.
