MEGASITE AS BURDEN AND CHALLENGE FOR REGIONAL GOVERNMENT OF ARAGONSandra Ortega BravoGeneral Manager of Sustainability29 September 2016
ORIGIN OF THE PROBLEM • Lindane is a organochlorine (C6H6Cl6), gamma hexachlorocyclohexano isomer, widely used until 1991 as insecticide in agriculture and for the treatment of parasites in ranching as well as of louses and mange in human beings. • From 2009 it has been prohibited or restricted in the majority of the countries under the Agreement of Stockholm of Organic Persistent Pollutants. • The isomers HCH are considered to be like dangerous for being: • • Toxins • • Carcinogenic • • Persistent • • Mutagenic • • Teratogenic and • • Bioaccumulative
ORIGIN OF THE PROBLEM • From 1975 to 1988, Inquinosa manufactured Lindane in Sabiñanigo (Spain), producing 27 tons per day of HCH (Persistent Organic Compound), only the gamma isomer (Lindane) was commercial use. • To produce 1 ton of lindane were generated between 8 and 10 tons of technical HCH (mixed isomers of HCH). Highly inefficient industrial process. • Waste production estimate by Inquinosa: • - 6.800 tons / year of solid waste: Isomers and HCH (which accounted for 85 to 90% of the production process) • - 300-500 tons / yearof liquid waste: (benzene, chlorobenzene, distillation bottoms, sludge production, etc)
ORIGIN OF THE PROBLEM 1975-1988: INQUINOSA manufactures lindane in Sabiñánigo 1975-1983: INQUINOSA uses Sardas landfill 1984-1992: INQUINOSA uses Bailinlandfill 1987: “Ecologists in Action” makes a complaint and denounces the pollutants discharges. complaintdischarges 1988: Government of Aragon prohibits the dumping of waste pollution of the river Gállego 1988-1992: INQUINOSA matterlindane and developscommercialformulations 1994: INQUINOSA leavesthefactory and evading

SITUATION OF LINDANE POLLUTION IN ARAGON Extreme complexity of the situation of contamination by pollution factors multicomponent and multiafection. Location of landfills without isolation and a totally unfavorable hydrogeological conditions. MULTICOMPONENT pollution by the diversity of waste (Benzene, policlorobencenos, polychlorophenols, isomers of HCH, methanol and other alcohols, fatty acids, dioxins and furans, others ...) aHCH, bHCH, gHCH, Pentachlorobenzene, dioxins and furans included in the Stockholm Convention. MULTIAFECTATION component because pollution affects land, water and bed of the river Gállego. Total volume of waste exceeds 130.000 tons of HCH solid, 6.000 tons of liquid waste (DNAPL) and about 1 million tonnes of contaminated land. All this means contamination of 50 ha of land and three aquifers, with possible conditions to the bed of Gallego and reservoirs.
How much have been spent on decontamination activities? 57 € million of investment between 1992 and 2016
Departamento de Desarrollo Rural y Sostenibilidad INVESTMENTS HCH DESCONTAMINATION IN SABIÑANIGO (SPAIN) From 1992 to 2016 it has invested 57 M€ to contain pollution: - 9% European Union (FEDER) - 21% Central government of Spain - 70 % Government of Aragón, own resources It is estimated that require at least 550M€ over the next 25 years to solve the problem. Advance Bailín is to find global solutions for managing waste HCH (lindane) in Europe. Aragón has reference decontamination technology (DNAPL). 25 years of experience.
Departamento de Desarrollo Rural y Sostenibilidad GOVERMENT OF ARAGON CURRENT ACTIONS • Implementation of technical human resources: Unitforthe integral managementforDecontamination of Lindane. • MonitoringProtocol Gallego River – Civil Protection. - Dailyfollow up. (22 municipalities 40.000 persons) • DNAPL Descontamination. • Implementation and ongoingmonitoring of hydrogeologicalsystem in bothlandfills. • Collaboratioon and regular ommunicationwithall social, institutional and scientificsinvolvedagents. • Technology and R and D development: ISCO LIFE PROJECT, nanoparticles, surfactantsinjection, technosols. • Implementation of a procedure for Public Procurement Innovation later this year 2016.
DISCOVERED LIFE PROJECT • “Lab to field, soil remediation demonstrative project: New isco application to DNAPL multicomponent environmental problem” • In situ chemical oxidation or ISCO tested for decontaminating soils. • Consortium: Government of Aragon, IHPA and public company SARGA. • Project duration and budget : 2014 – 2017. In Situ oxidation test in June and July 2016. Total budget of the project 1.123.305€ • Results are very promising and with great potential for technology to extrapolate similar situations anywhere in Europe
Departamento de Desarrollo Rural y Sostenibilidad Challenges: • Curbing contamination, ensure water use and air, environmental quality and public health. • Get institutional support for the necessary financial resources to address the problem of pollution (estimated cost for descontamination 550M€) • Technological development to eliminate waste HCH mixed with other hazardous waste (Sardinian) mixed with soil (bailin) and total decontamination of the dense phase (DNAPL). Reaching a solution will require a complex and costly process in the search for technological solutions, development RDI. Aragon already has valuable experience in this area wih more of 25 years. • Define the necessary and applicable in situ technologies for comprehensive decontamination water, soils, aquifers and rivers. • Promote the R + D + i for generating the necessary knowledge to solve the problem. and drive a technological pole in Aragon for decontamination technologies and sustainable chemistry focusing on circular economy to extrapolate to other contaminated sites in Europe for global solutions. www.aragon.es/lindano
