TECHNICAL FACT SHEETS ON THE RELEVANCE OF INDUSTRIAL GROUNDWATER MONITORING NETWORK: A TOOL FOR PRIORITY ACTIONS AND POLLUTION MANAGEMENT

Abstract : The French Mediterranean coastline with a length of 1000 km includes about 120 environmentally-sensitive industrial facilities. More than a half of these facilities are responsible for soil or groundwater contamination; with a groundwater monitoring network of nearly 1000 points, a high quality monitoring should be expected. The water department of the French geological survey (BRGM) supports the local authorities to control groundwater quality in environmentally-sensitive facilities, supervised by the French regional directorate for environment. A global perspective on good chemical status can only be obtained if monitoring is based on the local environment and the expected contamination. The BRGM developed a technical fact sheet on the relevance of the industrial groundwater monitoring network, designed for the regional authorities to define further priority actions with environmentally-sensitive facilities. A fact sheet presents environmental information in a standardised manner: industrial background information, local hydrogeology, and the availability of analyses data as well as the cartography of the monitoring network distribution. The relevance of specific groundwater monitoring network is given as well as the adequacy of the monitoring frequency and the prescribed substances. Data statistics enable to highlight missing data or a lack of available data. The crossed viewpoints of hydrogeology and contaminated sites provide fact sheets with an indicator of monitoring relevance, quality and comprehensiveness, to define further priority actions. They can also provide inputs for the environmental monitoring that is required for any new facility applying for a permit. A majority of test facilities presented lacks of monitoring in terms of evaluation of contamination extension and evolution, responsible for organic micro-pollutants close to drinking water supplies.
