The effect of agrochemical use in agricultural activities on the drinking water quality of ground and surface water within Agogo, a prominent tomato growing area in the Ashanti region of Ghana was assessed by monitoring physicochemical parameters, trace metals and microbial quality of two water sources. Levels of contamination were greater in surface water than groundwater. Trace metal levels (mg/L) were 1.40, 0.12, 0.08 and 0.18 in surface water and 0.08, 0.10, 0.05 and 0.08 in groundwater for Fe, Pb, Zn and Cd, respectively. Lead and Cd in surface and groundwater exceeded USEPA maximum acceptable levels (MCLs) for drinking water. Bacterial indicator numbers (geometric means/100 mL) in surface water varied from 9.35 x 10⁵ to 1.57 x 10¹¹ for total coliforms, 4.15 x 10⁴ to 2.10 x 10⁷ for faecal coliforms and 2.80 x 10 to 3.25 x 10² for enterococci, but none was found in groundwater.
评估了加纳阿散蒂地区阿戈戈（Agogo）一个重要的番茄种植区农业活动中使用农用化学品对地下水和地表水饮用水水质的影响，监测了两种水源的理化参数、痕量金属和微生物质量。地表水中的污染水平高于地下水中的污染水平。地表水和地下水中的痕量金属（mg/L）水平分别为 Fe 为 1.40、0.12、0.08 和 0.18，Pb 为 0.08、0.10、0.05 和 0.08，Zn 为 0.08、0.10、0.05 和 0.08，Cd 为 0.08、0.10、0.05 和 0.08。地表水中的 Pb 和 Cd 以及地下水中的 Pb 和 Cd 均超过美国环保署（USEPA）饮用水最大可接受水平（MCL）。地表水中的细菌指示物数量（几何平均值/100mL）在总大肠菌群中从 9.35 x 10⁵ 到 1.57 x 10¹¹，在粪大肠菌群中从 4.15 x 10⁴ 到 2.10 x 10⁷，在肠球菌中从 2.80 x 10 到 3.25 x 10²，但在地下水中均未发现。
