Key issues
According to the results of the ASROCKS demonstration sites, the most important questions to address when a new aggregate production site or construction site is being set up are as follows:
- Is the new site located within an arsenic province, i.e. in the geological region with naturally elevated arsenic concentrations?
- What are the rock types at the site?
- Is there any information on elevated arsenic concentrations at the site or in its surroundings?
- What is the direction of surface water runoff from the site?
- Are there any valuable natural resources or protected ecosystems or species in the surroundings?
- Are there any private household wells or important groundwater aquifers nearby (within 300–500 m)?
- What is the planned land use and would this involve playgrounds or residential areas?
