The Strategic Environmental Action Plan against the lindane waste in Aragon is a description of the challenge that the management of the lindane-related waste formulates.
The Government of Aragon presents the external evaluation of the Strategic Plan for the time-frame 2016-2018 and the proposal of improvement, including the monitoring indicators
Comprehensive Action Plan for the lindane decontamination in Aragon positively evaluated, and improving
Good practices in waste management in the European Union
In November 2016, the EU published the report “Lindane (persistent organic pollutant) in the UE”, and interchange of good remediation practices, elaborated by the Directorate of the Directorate-General for Internal Policies, Policy Department C: Ctizen’s Rights and Constitutional Affairs. This document goes over the legislation of the lindane waste, the conditions of the sites with lindane manufacturing waste in the EU and an introduction to the state of the art in lindane waste decontamination. It should be noted that the creation of the three Monitoring Committees in Aragon has been included in the list of “Good Practices” of the document, as a guarantee of the coordination and participation in the finding of solutions (page 66). One of the main ideas of the document is the need of applied research to find feasible decontamination solutions. Specifically, it emphasizes that in the “Biological methods: soil and water bioremediation”, “…further research, especially field studies, is needed to better understand the factors affecting the bioremediation and to improve their efficiency.”
Ecological monitoring in the Gallego river basin
An annual report regarding the actions to determine the ecological state of the Gallego river basin (Bailin-Sabiñánigo) is being done from 2006 within the “Monitoring and control Plan of Bailin and Sardas HCH landfills”. The rivers Gallego, Aurin and Basa are analysed in the mentioned report. These monitoring reports are part of the Integrated Environmental Authorisation. Samples are taken every year in the same sampling points. Also, the same indicators are used. 13 to 16 points are analysed, including sampling of microphytes, macroinvertebrate, hydromorphological analysis (QBR Index- quality of the river forest index -, and IHF index – fluvial habitat index -), study of the fish populations and analysis of water and sediments. Therefore, these reports give a representative image of the historical state of the basin.
The HCH, acronym of the chemical compound hexachlorocyclohexane, is the main residue of the lindane manufacturing. It is a bioacumulable compound. A bioacumulable substance is that one that is incorporated to the tissues of the living beings and can increase its concentration through the food chain. However, it does not remain in the organisms forever, but it is slowly metabolised. The time of metabolisation of the HCH, expressed in “half-time elimination rate”, in bovines is from 4 to 22 weeks, according to the Basque Food Safety Foundation (ELIKA). The “half-time elimination rate” can be understood as the time that an organism takes to reduce the HCH plasmatic concentration to the half.

Electronic Agrienvironmental Journal
The Electronic Agrienvironment Journal is a monthly publication that gathers information regarding the Department of Rural Development and Sustainability of the Government of Aragon. Along the last years, a series of information related to the HCH waste has been published. Check the mentioned information at the following link:
Detailed assessment of the Inquinosa wall surfaces: production buildings and aauxiliary buildings
In February 2019, and exhaustive analysis of the contamination level from lindane production waste at the walls of the industrial ruin of Inquinosa has been completed. 62 samplings have been performed, separating, in each sample external-internal painting, internal-external plasting and block wall. The assessment of this information will be usefull for defining the patterns for the dismantling of the buildings in safer conditions.
