从一个地下水池中采集了12个样本，其中含有由溶解有机物（DOM）的腐殖质成分引起的显著颜色。根据表观分子尺寸（AMS）分布对原始源样品中的DOM进行了表征。结果表明，AMS分布（以溶解有机碳、紫外吸收率和三卤甲烷形成电位表示）可以深入了解潜在的处理工艺适用性。臭氧氧化对颜色较低、AMS较低的源显示出最大的优点，而混凝或膜处理更适合颜色较高、AMS较高的源。活性炭吸附没有明确的处理生态位（即AMS范围）。包括12个参考文献、表格和图表。

Twelve samples were obtained from a groundwater basin containing significant levels of color caused by the humic constituents of dissolved organic matter (DOM). The DOM present in raw source samples was characterized according to apparent molecular size (AMS) distribution. The resultant AMS distributions--expressed in terms of dissolved organic carbon, UV absorbance, and trihalomethane formation potential--were found to provide insight into potential treatment process applicability. Ozonation showed the most merit for lowercolor, lower-AMS sources, whereas coagulation or membrane treatment was more suitable for higher-color, higher-AMS sources. No clear treatment niche (i.e., AMS range) was identified for activated carbon adsorption. Includes 12 references, tables, figures.
