Brief description:

Since 2004, the Department of Charente has been the owner of a former industrial site of 1.08 hectares, located in a residential area of the city of Angoulême (rue Jules Durandeau). This site was operated from 1936 to 1984 by the company LECLANCHÉ and then SAFT for the manufacture, repair and recharging of batteries and accumulators.

The results of the various investigations carried out since 2018 as part of the interpretation of the environment and management plan have confirmed the presence of numerous impacts on the site:

  • At the groundwater level: presence of VOCs (high levels of trichloroethylene, tetrachloroethylene, 1,2-cis-dichloroethylene and vinyl chloride, significant levels of C5-C40 hydrocarbons, BTEX) and TME (notable levels of arsenic, nickel, lead and mercury).
  • In air and soil: presence of VOCs (high levels of trichloroethylene and tetrachloroethylene and significant and specific levels of 1,2-dichloroethylene cis, 1,2-dichloroethylene trans, chloroform and vinyl chloride).
  • In the soil environment: presence of EMT (high levels of mercury, cadmium, nickel, zinc, lead) and VOCs.


In view of the rehabilitation challenges of the site (especially health and environmental), a specific governance structure was set up. Alongside public and private partners (Angoulême City Council, Charente Department, Charente Prefecture, Regional Health Agency and Regional Directorate for the Environment, Spatial Planning and Housing, engineering companies), representatives of local residents (associations “Saint-Cybard Environnement” and “Comité de quartier Saint-Cybard”) are part of the monitoring committee and the scientific committee.
