This textbook employs a technical and quantitative approach to explain subsurface hydrology and hydrogeology, and to offer a comprehensive overview of groundwater-related topics such as flow in porous media, aquifer characterization, contaminant description and transport, risk assessment, and groundwater remediation. It describes the characterization of subsurface flow of pristine and polluted water and provides readers with easily applicable tools for the design of water supply systems, drinking-water source protection, and remediation interventions. Specific applications range from groundwater exploitation as a drinking water supply to the remediation of contaminated aquifers, from the definition and safeguarding of drinking-water sources to the assessment of human health risks in connection with groundwater contamination events. The book represents an ideal learning resource for upper-undergraduate and graduate students of civil engineering, environmental engineering, and geology, as well as practitioners in the fields of water resource management and environmental protection who are interested in groundwater engineering and technical hydrogeology.

Nanomaterials for the Detection and Removal of Wastewater Pollutants assesses the role of nanotechnology and nanomaterials in improving both the detection and removal of inorganic and organic contaminants from wastewater that originates from municipal and industrial plants. The book covers how nanotechnology is being used to remove common contaminants, including dyes, chlorinated solvents, nitrites/nitrates, and emerging contaminants, such as pharmaceuticals, personal care products and pesticides. Sections cover nanofiltration, adsorption and remediation. Nanomaterial immobilization recovery is also addressed, along with the quantification of heat/mass transport limitations, sizing aspects and transport phenomena. Finally, regulatory aspects regarding contaminants and nanoparticles in the environment are covered. This book is an important resource for both materials scientists and environmental scientists looking to see how nanotechnology can play a role in making wastewater a less hazardous part of the global ecosystem.

Il testo fornisce le conoscenze necessarie per affrontare, con un approccio quantitativo, i molteplici aspetti connessi al flusso delle risorse idriche sotterranee (acque di falda) e alla propagazione e bonifica di contaminanti nei sistemi acquiferi.

Vengono illustrate le proprieta fondamentali che definiscono la capacita di immagazzinamento, trasporto e rilascio dell acqua negli acquiferi, e successivamente, descritte le metodiche per la determinazione di tali parametri tramite l esecuzione e l interpretazione di prove di falda, di pozzo e di laboratorio. A partire dalla classificazione chimico fisica-tossicologica dei contaminanti vengono, quindi, analizzati i meccanismi di propagazione e illustrate le soluzioni analitiche dell equazione del trasporto di massa nei mezzi porosi. L ultima parte del testo e dedicata alla caratterizzazione e bonifica degli acquiferi contaminati.

Il testo e rivolto sia agli studenti universitari, sia ai professionisti che debbano affrontare con un approccio quantitativo tali problematiche.
