| dc.description.abstract | This study aimed at assessing the effectiveness of Environmental Impact (EI) mitigation measures in protecting ground water resource. The study assessed the quality of ground water and availability of water for local users in villages surrounding Buzwagi gold mine project which were Mwendakulima, Mwime and Nyihogo. Water and sediment samples were collected from wells in the villages whereby 28 water samples and 22 sediment samples were collected for every three months for a period of 297 days. The samples were analyzed for electrical conductivity, pH, cyanide and some selected heavy metals. Meteorological data were collected from Tanzania Meteorological Agency (TMA). The geological and topographical maps of the area were taken from Geological Survey of Tanzania (GST). The Social data were obtained through interviews. The results showed high levels of Mn, Cr, Zn, Pb and Fe in sediments while Pb and Fe levels in water exceeded the Tanzania Bureau of Standards (TBS) limit for drinking water in some wells. In addition CN was observed in wells which are closer to the mine than those far from the mine. The net amount of water in the aquifer was predicted to be 888 m3 in the next 5 years which may not be sufficient for community demand while high CN level was predicted in the wells closest to the TSF. It was concluded that not all the mitigation measures suggested in the EIA were implemented or the impact prediction and evaluation was not correct. It was recommended that the pumping rate of water should be low during dry season, the water flow metre should be installed and that the TSF’s liner should be regularly checked to ensure zero discharge as stated in the Environmental Management Plan (EMP).Further study was also recommended with more number of samples and prolonged sampling period. | en_US |
