WATER AND WASTE

An environmental issue for which we provide impact assessments and monitoring services.

  • Discharge studies (sediment, wastewater), impact on coastal water quality, bacterial count, contamination risk, eutrophication
  • Contamination risk forecasts

Impact study of river watersheds on coastal water eutrophication

IFREMER, ONEMA, English Channel-Bay of Biscay, 2013-2014

  • Use of a biogeochemical model to map coastal areas subject to river discharges.
  • Evaluation of optimal nitrate and phosphate loads to achieve a good ecological status in the sub-regions of the European Marine Strategy Framework Directive (MSFD).
  • Impact of optimal load values on concentrations of chlorophyll and dissolved oxygen in these sub-regions.

Impact study of wastewater discharge on bacterial count

SUEZ, VINCI, Sri Lanka, 2015

  • Metocean condition analysis.
  • Development and use of metocean models associated with a module of transport and mortality of dissolved and particulate substances.
  • Contamination risk assessment on surrounding beaches.

Study of bathing water contamination by bacteria

SUEZ, DIEPPE MARITIME, English Channel, France, 2012-2015

  • Statistical analysis of historical water sampling data to assess the known risk of contamination, and analysis of circumstances that led to contamination events.
  • Development and use of metocean models associated with a transport and mortality module for dissolved and particulate substances.
  • Contamination risk assessment of bathing waters.

Operational forecast of bathing water contamination by bacteria

SUEZ, Cannes, France, since 2008

  • Development and use of metocean models associated with a terrestrial watershed and a wastewaster and rainwater networks model, and rainfall radar data.
  • Contamination risk assessment of bathing waters.
