Integrated stochastic modeling of pharmaceuticals in sewage networks

Pierre Claude Jean Queloz, Sylvain Coutu, Timothée Noé Pouchon

Pharmaceuticals and particularly antibiotics can harm sensitive aquatic species. Their occurrence in urban wastewater systems is the consequence of five successive processes: (i) ingestion of the substance, (ii) accumulation in the urine, (iii) excretion, ...

Modelling the effect of fluctuating herbicide concentrations on algae growth

Sylvain Coutu, Pierre-Jean Copin

Herbicide concentrations fluctuate widely in watercourses after crop applications and rain events. The level of concentrations in pulses can exceed the water chronic quality criteria. In the present study, we proposed modelling the effects of successive pu ...

Substance flow analysis as a tool for mitigating the impact of pharmaceuticals on the aquatic system

Luca Rossi, Sylvain Coutu, Jonas Margot, Htet Kyi Wynn

Pharmaceuticals constitute an important environmental issue for receiving waters. A holistic approach, taking into consideration the sources of these compounds (hospitals, domestic use), discharges (wastewater effluent, combined sewer overflows) and relate ...

Temporal dynamics of antibiotics in wastewater treatment plant influent

David Andrew Barry, Luca Rossi, Sylvain Coutu, Htet Kyi Wynn, Vera Wyrsch

A yearlong field experimental campaign was conducted to reveal time scales over which antibiotic fluxes vary in the influent of a wastewater treatment plant (WTP). In particular, sampling was carried out to ascertain the amplitudes of monthly, daily and ho ...

Model falsification diagnosis and sensor placement for leak detection in pressurized pipe networks

Ian Smith, Sylvain Coutu, James-Alexandre Goulet

Pressurized pipe networks used for fresh-water distribution can take advantage of recent advances in sensing technologies and data-interpretation to evaluate their performance. In this paper, a leak-detection and a sensor placement methodology are proposed ...

A computational platform for integrated modelling of micropollution in the urban environment

David Andrew Barry, Luca Rossi, Sylvain Coutu, Timothée Noé Pouchon

Anthropogenic chemical contaminants are found routinely in our water resources. Although most of these compounds are usually present at low concentrations, they are of concern due to their ecotoxicity, antibacterial resistance and potential harm to human h ...

Temporal variability of antibiotics fluxes in wastewater and contribution from hospitals

David Andrew Barry, Luca Rossi, Sylvain Coutu

Significant quantities of antibiotics are used in all parts of the globe to treat diseases with bacterial origins. After ingestion, antibiotics are excreted by the patient and transmitted in due course to the aquatic environment. This study examined tempor ...

Modelling city-scale facade leaching of biocide by rainfall

David Andrew Barry, Luca Rossi, Sylvain Coutu, Chiara Rota

A methodology is presented for estimating, at the city scale, the amount of biocide released from facades during rain events. The methodology consists of two elements. First, leaching of a single facade is simulated using a two-region model, one region for ...

Methodology to account for uncertainties and tradeoffs in pharmaceutical environmental hazard assessment

David Andrew Barry, Luca Rossi, Sylvain Coutu

Many pharmaceutical products find their way into receiving waters, giving rise to concerns regarding their environmental impact. A procedure was proposed that enables ranking of the hazard to aquatic species and human health due to such products. In the pr ...
