沿沿着两个300米长的横断面（285个地下水样品）绘制了Grindsted垃圾填埋场渗滤液羽降梯度中有机化合物的分布图。在填埋场的边界处，溶解性有机物（以非挥发性有机碳（NVOC）计）的浓度升高了30-110 mg C L-1，在填埋场的下坡130 m处，NVOC已降至背景水平，为1-3 mg C L-1。超过15种有机化合物被确定在地下水中的下降梯度边界的垃圾填埋场与苯，甲苯，二甲苯和二甲苯为主。没有发现杀虫剂，但发现了一些苯氧基酸，这可能是已知杀虫剂的代谢物。在距离垃圾填埋场约60米的地方，大多数特定的有机化合物已无法检测到。由于稀释和吸附显然不能占的特定的有机化合物的消失在第一个60米的羽流，有人建议，大多数的特定的有机化合物降解的厌氧羽流下产甲烷/硫酸盐还原或铁还原条件。调查表明，含水层具有很大的自然衰减能力
The distribution of organic compounds in the leachate plume downgradient of the Grindsted Landfill was mapped along two 300 m long transects (285 groundwater samples). At the border of the landfill, elevated concentrations of dissolved organic matter 30-110 mg of C L -1 (measured as nonvolatile organic carbon, NVOC) were found. In a distance of 130 m downgradient of the landfill, the NVOC had decreased to background level, which is 1-3 mg of C L -1 . More than 15 organic compounds were identified in the groundwater at the downgradient border of the landfill with benzene, toluene, ethylbenzene, and xylenes as dominating. No pesticides were identified, but some phenoxy acids, which could be metabolites of known pesticides, were found. In a distance of approximately 60 m from the landfill, most of the specific organic compounds were no longer detectable. Since dilution and sorption apparently cannot account for the disappearance of the specific organic compounds within the first 60 m of the plume, it is proposed that the majority of the specific organic compounds were degraded in the anaerobic plume under methanogenic/sulfate-reducing or iron-reducing conditions. The investigation indicates that the aquifer has a substantial natural attenuation capacity
