En julio de 2009 y tras el proceso de participación pública y alegaciones, anunciado a nivel internacional, se han aprobado definitivamente las “Australian Guidelines” 23 y 24. Las normas reflejan años de bagaje en la técnica MAR. Facilitadas por Peter Dillon, coordinador del Grupo de trabajo de Gestión de la recarga de acuíferos de la Asociación Internacional de Hidrogeólogos (IAH-MAR), se encuentran accesibles a través del enlace siguiente:
- AUSTRALIAN GUIDELINES 23 FOR WATER RECYCLING: MANAGING HEALTH AND ENVIRONMENTAL RISKS (PHASE 2) STORMWATER HARVESTING AND REUSE. July 2009.
- AUSTRALIAN GUIDELINES 24 FOR WATER RECYCLING: MANAGING HEALTH AND ENVIRONMENTAL RISKS (PHASE 2). MANAGED AQUIFER RECHARGE. July 2009.

Following final ministerial approvals and technical editing, the Managed Aquifer Recharge and Stormwater Harvesting and Reuse modules of the Australian Guidelines for Water Recycling have been posted today on an Australian Government website at the attached link:
The MAR Guidelines have more streamlined risk assessment processes than the draft version whose web link I circulated in May 2008. However technical substance is mostly the same. Sections on ecosystem protection, metal mobilisation, pathogen attenuation and trace organic attenuation have been substantially improved with recent data and reports and reviewer input.
This has been approved by a national working group,a joint steering committee and three ministerial councils each containing all relevant state and commonwealth ministers. While it is published under the Australian Guidelines for Water Recycling these guidelines apply to all sources of water, including natural waters and drinking water.
The Guidelines follow the WHO and Australian risk management approach to water quality guidance. They allow for iterative development of information by offering a staged approach to risk management in concert with project development. They cover hydrogeological / geotechnical and greenhouse gas hazards as well as water quality hazards. They also address operational issues including clogging and recovery efficiency, as well as risk management plans and monitoring. Although they are long (200+pages) I hope you find them helpful.
