Hydrogeochemical surveys of surface and ground waters in Central Macedonia found arsenic concentrations above the permissible level for drinking water (Directive 98/83/EC). About 30.000 people are drinking water exceeding the permissible level (10 μg/L) for arsenic and in some potable water wells the arsenic concentrations is exceeding 70 μg/L. The presence of arsenic is attributed to natural sources such as certain clay beds in river delta deposits, and geothermal waters, as well as anthropogenic causes such as mine waters. A new innovative technology that is based on iron filings was field tested at the potable water supply well of the municipality of Chalastra and removed arsenic to levels below the drinking water standards
