One of the six major meteoric lakes in the world, Lake Bosomtwe, is of great ecological significance for Ghanaians and the scientific community, most importantly for agricultural and human consumption. Water samples (n = 30) were collected to analyze the hydrogeochemical characteristics and water quality of the lake. Statistical methods including correlation, principal component, cluster analysis, Gibbs ratio, and the Piper–Trilinear diagram were used to analyze parameters. The Water Quality Index revealed that the lake water is not suitable for human consumption because measured pH, temperature, total dissolved solids, color, and bicarbonate exceeded their respective thresholds on all occasions. The calculated sodium absorption ratio (13.7–14.8) and soluble sodium percentage (94.43–95.43%) showed that the lake is not appropriate for irrigation as they exceeded their respective limit of 2 and 60%. The Gibbs ratio revealed that rock–water interaction is the underlying mechanism for water evolution. The Piper–Trilinear diagram revealed that alkalies earth and weak acids dominate the water chemistry of the lake. The dominant cation is sodium (82.22%), while the dominant anion is bicarbonate (79.39%). Five monitoring stations were identified, and the water quality was influenced by diverse anthropogenic and natural sources. The findings will provide a reference for policymakers and decision-makers at Lake Bosomtwe.

Bosomtwe湖是世界上六大陨石湖之一，对加纳人和科学界具有重要的生态意义，最重要的是农业和人类消费。水样（n= 30）被收集以分析该湖的水文地球化学特征和水质。统计方法包括相关性，主成分，聚类分析，吉布斯比率和Piper–Trilinear图，用于分析参数。水质指数显示，湖水不适合人类食用，因为测得的pH，温度，总溶解固体，颜色和碳酸氢盐在所有情况下均超过各自的阈值。计算得出的钠吸收率（13.7–14.8）和可溶性钠百分比（94.43–95.43％）表明该湖不适合灌溉，因为它们超过了各自的2％和60％的极限。吉布斯比率表明，岩水相互作用是水演化的潜在机制。Piper-Trilinear图表明，碱土和弱酸主导着湖泊的水化学。优势阳离子为钠（82.22％），而优势阴离子为碳酸氢盐（79.39％）。确定了五个监测站，水质受到各种人为和自然资源的影响。这些发现将为博索姆特湖的决策者和决策者提供参考。
