PREPARATORY ACTIONS RESULTS (A1)

The objective foreseen in our preparatory actions was to gather all the available information to successfully implement the ISCO pilot test. In a first phase, a diagnosis of the initial conditions of the area was essential.

An exhaustive analysis has lead to the diagnosis and characterization of the foreseen recirculation cell in which it is intended to implement the pilot test. The final aim has been the design of the more suitable test to the existing aquifer.

During 2014-2015 we have carried out these two important tasks to continue the development of the project with success, both have concluded in a previous pilot test design.

You can download the three documents summarizing the work done by AECOM-URS http://www.aecom.com/es/ and supervised by the Discovered Life Technical Committee

 

DIAGNOSIS -The first report presents a diagnosis of the area and reviews the results of the laboratory works performed by the General Directorate of Environmental Quality of the Government of Aragon. The report describes the initial conditions for the test from the points of view of the site, the environment and the features of pollutants as well as from the ISCO technology perspective.

CHARACTERIZATION -The report highlights the characteristics of the recirculation cell, as well as the necessary preliminary works to carry out the boreholes that will be necessary to control and inject the oxidant during the test. In addition, the report includes the determinants that may allow establishing the necessary pre-conditions taking into account the hydrogeological parameters of the area in order to draft the final design of the pilot test. You may find here a short presentation.

DESIGN - This report focus on the pilot test approach taking into account the test zone adaptation, such as tracks and platforms to built and the basic features of the test and control wells. It is also described the pumping and injection tests and the parameters that are necessary to monitor the proper test execution. Injection volume and flow rates as well as the oxidant demand and activator doses in the aquifer are quantified. The design plan several injection events. For more details check the report.

 PRELIMINARY WORKS AND FIELD IMPLEMENTATION OF EQUIPMENT - The preliminary works were focused on re-evaluating the initial approach of the test, adjusting the design parameters and defining the necessary equipment. They consisted of:

 

ADJUSTMENT OF THE ISCO DESIGN -  The aim of this report is to update the parameters before the ISCO implementation. The results obtained in the previous phases have permitted to reevaluate the initial planning and adjust the parameters designed previously.

STUDY OF APPLICATION OF THE ISCO TECHNOLOGY TO FULL-SCALE (B2)

 A study has been carried out to analyze the viability of the application of ISCO technology on a large scale in the environment of the old Bailín landfill.

Full Scale

 In addition, a Methodological Guide has been prepared for the implementation of In-Situ Chemical Oxidation, which facilitates the replicability and transfer of the knowledge generated in the framework of the project to other similar sites.
