摘要

加纳政府在2017年至2018年期间禁止手工和小规模采矿(ASM)作业,这是其解决非法采矿活动(也称为“galamsey”作业)造成的社会环境问题战略的一部分。本研究评估了Konongo水处理厂(WTP)在实施“galamsey”操作禁令前后抽取原水进行处理的水质趋势。科农戈WTP的主要原水来源是阿努鲁河。2006年至2019年理化水质的二级数据来自科农戈WTP和加纳水务有限公司(GWCL)的阿尚蒂地区水质保证单位。采用Mann-Kendall季节性检验,利用XLSTAT统计工具确定水质数据的趋势。结果显示,在禁止“galamsey”活动之前,水质的颜色、浑浊度、温度、总铁和硫酸盐含量均有统计学显著(5%显著水平)上升趋势。有统计上显著的证据表明,禁止“伽兰西”操作后,总硬度、钙硬度、浊度、总碱度和氯化物呈下降趋势。

Impact of the ban on illegal mining activities on raw water quality: A case-study of Konongo Water Treatment Plant, Ashanti Region of Ghana
The Government of Ghana prohibited Artisanal and Small-Scale Mining (ASM) operations from 2017 to 2018 as part of its strategy to address the socio-environmental issues caused by illegal mining activities, also referred to as “galamsey” operations. This study assessed the trend in the water quality of raw water abstracted at the Konongo Water Treatment Plant (WTP) for treatment before and after implementing the ban on “galamsey” operations. The main source of raw water for the Konongo WTP is the Anuru River. Secondary data on physicochemical water quality from 2006 to 2019 was sourced from the Konongo WTP and the Ashanti Regional Water Quality Assurance Unit of Ghana Water Company Limited (GWCL). Mann-Kendall seasonality test was used to determine trends in the water quality data using XLSTAT statistical tool. The results showed a statistically significant (5% level of significance) upward trend in colour, turbidity, temperature, total iron, and sulphate before the ban on “galamsey” activities. There was statistically significant evidence of a downward trend in total hardness, calcium hardness, turbidity, total alkalinity, and chloride after the ban on “galamsey” operations.
