Arsenic, drinking-water and health risk substitution in arsenic mitigation: A discussion paper


The table below summarises the major issues in relation to risk substitution and the potential for control within design and construction and operation and maintenance. This table does not attempt to rank the technologies with regard to their use, which has been done by the NCE, but simply sets out what issues will need to be considered.

For all technologies, ongoing support through surveillance and hygiene education will be essential to ensure risk management is effective in the long-term up to the point of consumption.

It is recommended that arsenic removal technologies, particularly those that work at a community level, be considered as an option for the emergency response.
