["注:1.执行标准是《生活饮用水卫生标准》（GB5749-2022）；\n     2.浑浊度是反映天然水及饮用水的物理性状的重要指标。单位采用NTU表示，是英文Nephelometric Turbidity Units的缩写，为散射式浊度单位；\n     3.细菌学指标通常采用CFU/mL或 CFU/100mL表示，为菌落总数单位。其中CFU是英文Colony-forming Units的缩写，代表菌落形成单位。\n     4.pH是溶液中氢离子活度的一种标度，也就是通常意义上溶液酸碱程度的衡量标准。通常pH是一个介于0和14之间的数,当pH<7的时候,溶液呈酸性,当pH>7的时候,溶液呈碱性,当pH=7的时候,溶液呈中性。\n     5.“<”表示检测结果低于该项目方法检出限；"]
