National Institute of Statistics, 2004 CASE STUDIES BAIA MARE - TECHNOLOGICAL ACCIDENT AND TRANSBOUNDARY POLLUTION JANUARY AND MARCH 2000 • Two tailings dam failures in Maramures county resulted in the release of 200 000 m³ of contaminated water and 40 000 tonnes of tailings into tributaries of the Tisa River, a major tributary of the Danube. • Following these accidents, Institute of Geography in collaboration with the University of Wales, UK initiated a research programme in northwest Romania to establish metal levels in rivers affected by the present and historic mining activities. 2000-2005 > 1100 SAMPLES, 350 SITES 2000 River systems categories: 1971 • with historical mining activity, presently inactive; •with historical and present mining activity; • with opportunities for the opening of new exploitations • with tailings dam accidents “Aurul” tailings pond “Bozânta 1” tailings pond (inactive) 2001 33 sites 828 km Zn concentrations in the River Sasar 2000 2001 2002 2003 target value imperative value Zn Bioavailable < target Bioavailable > target Bioavailable > intervention Use of private supply groundwater in Maramureş Samples taken from 96 households Zn concentrations in domestic wells vs. distance from river channel in the Someş catchment Concentration (ug/l) 10000 1000 100 10 0 500 1000 1500 Distance from channel (m) 2000 2500 Zn concentrations in domestic wells vs distance from contaminant point source in the Someş catchment 10000 Concentration (ug/l) 1000 100 10 1 0 2000 4000 6000 8000 Distance from mining point-source (m) 10000 12000 14000 Certej river basin: a mining affected basin • • nactive tailings dam • 1971 accident site • active tailings dam • • 78 km2 catchment containing the 40.05 km2 CertejCoranda mining concession.
