A decade of monitoring micropollutants in urban wet-weather flows: What did we learn?

Water Research, Journal Year: 2022, Volume and Issue: 223, P. 118968 - 118968

Urban wet-weather discharges from combined sewer overflows (CSO) and stormwater outlets (SWO) are a potential pathway for micropollutants (trace contaminants) to surface waters, posing threat the environment possible water reuse applications. Despite large efforts monitor in last decade, gained information is still limited scattered. In metastudy we performed data-driven analysis of measurements collected at 77 sites (683 events, 297 detected micropollutants) over decade investigate which most relevant terms 1) occurrence 2) risk aquatic environment, 3) estimate minimum number data be monitoring studies reliably obtain concentration estimates, 4) provide recommendations future campaigns. We highlight prioritized due their high critical levels compared environmental quality standards. These top-listed include contaminants all chemical classes (pesticides, heavy metals, polycyclic aromatic hydrocarbons, personal care products, pharmaceuticals, industrial household chemicals). Analysis 30,000 event mean concentrations shows fraction (> 50%) were below limit quantification, stressing need reliable, standard procedures. High variability was observed among events sites, with differences between micropollutant classes. The required reliable site (error bandwidth 1 around "true" value) depends on individual micropollutant. median 7 CSO (2 31, 80%-interquantile) 6 SWO (1 25 80%-interquantile).

Addressing the challenges of combined sewer overflows

Environmental Pollution, Journal Year: 2023, Volume and Issue: 343, P. 123225 - 123225

Europe's ageing wastewater system often combines domestic sewage with surface runoff and industrial wastewaters. To reduce the associated risk of overloading treatment works during storms, to prevent backing-up into properties, Combined Sewer Overflows (CSOs) are designed networks release excess discharge rivers or coastal waters without treatment. In view growing regulatory scrutiny increasing public concern about their excessive frequencies potential impacts on environments people, there is a need better understand these allow prioritisation cost-effective solutions.We review: i) chemical, physical biological composition CSOs discharges; ii) spatio-temporal variations in quantity, quality load overflows spilling receiving waters; iii) ecosystems economies. Despite investigations illustrating frequency CSOs, data spill loading pollutants too few reach representative conclusions, particularly for emerging contaminants. Studies appraising also scarce, especially contexts where multiple stressors affecting waters. Given costs addressing problems, but likely long-term gains (e.g. economic stimulation as well improvements biodiversity, ecosystem services, health wellbeing), we highlight here bolster evidence gaps. We advocate no-regrets options alleviate CSO problems taking consideration costs, carbon neutrality, benefit community well-being. Besides pragmatic, risk-based investment by utilities local authorities modernise systems, include more systemic thinking, linking policy makers, consumers, regulators, shift from issues integrated catchment solutions aim reducing contributions drainage water consumption; broader societal responsibilities example through improved regulation, behavioural changes consumption disposal waste networks, greater cost-sharing use.
