Description

The Brazilian Synchrotron Light Laboratory (LNLS) of the Brazilian Center for Research in Energy and Materials (CNPEM) jointly with Teesside University (UK) will host the third 3rd Groundwater Remediation using Nano/biotechnology with focus on the Contaminated Resources in Brazil (GRUN). This one-day workshop will be held on November 10, 2023, as one of the satellite events of the 33rd Annual LNLS Users Meeting.

The third edition of the GRUN Conference focuses on nanotechnology and novelty remediation processes for groundwater and soil, using nano and biotechnology, among others. Invited speakers from around the world will discuss the state-of-the-art in groundwater and soil remediation technologies. It will also have speakers from Brazil who will discuss the current state of knowledge regarding Brazilian groundwater resources.

The purpose of this conference is to bring together an interdisciplinary group of researchers and engineers to collectively explore how these technological advances can be applied to Brazilian groundwater and soil systems. It is expected a wide range of participants including scientists, engineers, academics, industry representatives, and governmental agents.

GRUN Conference aims to further grow a community of scientists with special interest in groundwater remediation and we encourage you to contribute with an abstract to be presented as oral or poster presentations.

Title: Use of nanotechnology in studies of urban aquifer contamination in the São Paulo State

Abstract: Nitrate contamination is almost ubiquitous in urban aquifers, becoming a challenge for the São Paulo State, where more than 80% of its services are supplied totally or partially by groundwater. Despite the several existing studies, there are critical scientific challenges that overcoming will contribute to the environmental management of extensive contaminated urban areas. Recently, advanced research groups have suggested the joint use of new tools, which would integrate with traditional hydrogeochemical techniques, including nanotechnology (synchrotron-based high-resolution and time-resolved X-ray imaging). This work proposes to apply, in a pioneering way, this tool in a very detailed study in a contaminated area in the city of Bauru (SP). For this purpose, the following activities are planned:

i) registration and treatment of previous data;

ii) determination of BAS flow conditions;

iii) reassessment of previous and recent nitrate concentrations;

v) installation of multi-level monitoring wells;

iv) sampling for physicochemical, chemical, isotopic, gas, microbiological, artificial sweetener analyzes of surface water, groundwater, rainwater, and wastewater samples;

v) collection of sediment/rock samples for porous media characterization and chemical, microbiological, isotopic and nanotechnology analyses. Undisturbed samples
collected from multilevel wells drilling will be sent to the Brazilian Synchrotron Light
Laboratory (LNLS) for the porous medium characterization on a micro scale.

The techniques adopted will be X-ray micro and nanotomography, using the synchrotron light source. In this beamline, high-resolution three-dimensional images are obtained from soil/rock samples with a maximum diameter of 1.5”. This technique allows for the study of the same sample at different resolutions without additional preparation, and 3D models of the porous medium can be made, which will provide subsidies for pore-scale modeling studies. Thus, it is expected that understanding nitrogen dynamics in the subsurface and the factors that control it will help public policies for dealing with urban aquifer contamination.

This is a satellite event to the 33rd edition of the Annual Users Meeting (RAU).
