自1978年以来，纽约州萨福克县一直在检查地下水中的农业和有机污染物。最近在私人水井中发现的特定化学品增加了人们对污染的担忧，并促使人们进行研究，以确定从地下水中去除农用化学品的成本效益系统。醋酸纤维素试验；螺旋缠绕薄膜复合材料；中空纤维膜表明，反渗透应被考虑用于去除农药和有机物。应在现场水上进行先导试验，以确保适当的工艺设计。 包括6个参考文献、表格、图表。

Suffolk County, N.Y., has examined its groundwater for agricultural and organic contaminants since 1978. Recent discoveries of specific chemicals in private wells increased the concern over contamination and spurred a study to determine a cost-effective system for removing agricultural chemicals from groundwater. Tests of cellulose acetate; spiral-wound, thin-film composite; and hollow fiber membranes showed that reverse osmosis should be considered for pesticide and organics removal. Pilot tests should be conducted on in situ water to assure proper process design. Includes 6 references, tables, figures.
