The objectives and missions of the Ecothèque are :
In the framework of Cigeo project :
To keep the memory of Environment and allow retrospective analysis from
Local food chain
Representative environmental samples (bioindicators)
Scientific samples from Ope observatory (project specific ex Agro-station
ICOS)
To involve and inform local stakeholders
Listening to local requests/ concerns
» numerous visits from representatives of local communities
Open access to learn about the ESB
» dedicated visitor center
To answer scientific community needs :
Provide samples for specific projects
May provide storage space for scientific or industrial projects
A building designed for purpose
2007 – 2012

The Andra’s ESB : An environmental specimen
bank for the Cigéo monitoring program
A purpose build Building
The sample strategy impacts the facility dimension!
Building size : Ecothèque is set to keep sample for a period of more
than 100 years
With current sampling plan today’s building is designed for at least
20 years of storage
Extra rooms are set aside for extensions on both sides
Data storage : Design of the data management system

Step one :
A selection of raw and processed samples representative of local production
or bioindicator of the chemical quality of the environment
Step two :
Continuous « Lesson learnt » process
Introduce new matrices? Which one, which frequency
1st July 2015 [DRD/GES/15-0199]
Milk Sampling
Milk : A local product
Agricultural activities are important in the OPE zone
Production of milk is present in the OPE reference sector but in decrease
Cheese, called “Brie de Meaux” is produced from the collected milk
OPE area is included within the area of Protected Designation of Origin
“Brie de Meaux”
A cheese diary is installed within the Ope reference sector
Milk is a matrix regularly watched and analyzed under regulatory
monitoring programs
Milk is part of the food chain
Milk Sampling
1st July 2015 [DRD/GES/15-0199]
Sampling plan
Locally produced milk is sampled
4 dairy farms are selected for their locations
1 dairy cheese
1 control dairy farm is also selected
Sampling frequency : currently 4 times/year
Creation of composite sample by dairy farm at the end of the year

Ecotheque role within Cigéo industrial project and beyond
Keep record of the reference state of the environment
Start sampling 4 years before the start of the project (if authorised)
Safe keeping of long term record of environmental evolution
Rigorous quality control of each storage steps
Data management adapted to long term storage
Allow retrospective analyses
To follow evolution of analytical techniques :
Decreasing LD/LQ
To answer change in regulation
Emerging contaminants
To answer local communities questions
Answer societal question :
» Strong demand for public consultation on industrial project
To contribute to scientific development
Provide trends over a long period of time
