TLDR
In this paper, a mechanistic simulation model predicting the response of water distribution systems (WDSs) operated with or without disinfectant residual toward accidental arsenic contamination is developed, based on a water distribution system model.Abstract:

Model-based investigation of the formation, transmission, and health risk of perfluorooctanoic acid, a member of PFASs group, in drinking water distribution systems.
TL;DR: In this paper, a new mechanistic model incorporating the derived knowledge about the zwitterionic/cationic FAs transformation to PFOA with the unsteady-state hydraulic characteristics of WDSs was developed.
Journal ArticleDOI
Contaminant Fate and Transport Modeling in Distribution Systems: EPANET-C
TL;DR: In this paper , the authors proposed EPANET-C, a computer-based tool for water distribution systems (WDS) quality modeling, which is based on EPANet-MSX.
Journal ArticleDOI
Control-Theoretic Modeling of Multi-Species Water Quality Dynamics in Drinking Water Networks: Survey, Methods, and Test Cases
TL;DR: In this paper , a host of novel state-space, control-theoretic representations of multi-species water quality dynamics are presented, which describe decay, reaction, and transport of chlorine and a fictitious reactive substance to reflect realistic complex scenarios in WDN.

Flexible decision-making framework for developing operation protocol for water distribution systems.
G. R. Abhijith,Avi Ostfeld +1 more
TL;DR: In this paper , a decision-making framework was developed to rank the possible water quality parameter-based operating alternatives (organic matter and residual chlorine levels at the source points) for WDS.

Contamination event diagnosis in drinking water networks: A review
Demetrios G. Eliades,Stelios G. Vrachimis,A. Moghaddam,Ioannis Tzortzis,Marios M. Polycarpou +4 more
TL;DR: A broad review of the theoretical, modeling, and computational developments in the area of contamination event diagnosis for water distribution systems is provided in this article , which is segmented into three main tasks, summarized as "Preparedness", "Event Detection and Isolation", and "Emergency Event Management".

Occurrence, genotoxicity, and carcinogenicity of regulated and emerging disinfection by-products in drinking water: a review and roadmap for research.
TL;DR: The brominated DBPs were the most genotoxic of all but have not been tested for carcinogenicity and highlighted the emerging importance of dermal/inhalation exposure to the THMs, or possibly other DBPs, and the role of genotype for risk for drinking-water-associated bladder cancer.

Comparison of arsenic(V) and arsenic(III) sorption onto iron oxide minerals: implications for arsenic mobility.
Suvasis Dixit,Janet G. Hering +1 more
TL;DR: The sorption data indicate that, under most of the chemical conditions investigated in this study, reduction of As(V) in the presence of HFO or goethite would have only minor effects on or even decrease its mobility in the environment at near-neutral pH conditions.
Journal ArticleDOI
Adsorption of arsenite and arsenate on amorphous iron hydroxide
TL;DR: In this paper, the authors measured the adsorption isotherms in solutions with ionic strengths of 0.01 at 25°C and measured over the arsenite and arsenate concentration range 10−7−10−3 M and the pH range 4−10.
