在爱尔兰，化粪池和其他现场系统是处理家庭污水的常用手段。在评估选址适宜性时，渗滤沟下的底土在衰减污染物，从而保护地下水方面具有重要作用。作为对爱尔兰四个具有不同底土特征的处理系统水力性能调查的一部分，对一系列样本进行了内分泌干扰化学物质（EDCs）分析，包括雌激素、表面活性剂和有机氧化合物。在所有四个地点都发现了EDCs，但浓度很低（通常低于可证实其存在的浓度），而且通常只在已知为渗滤污水的样品中发现。进一步的研究应该针对雌激素化合物，因为它们似乎比其他EDCs的浓度更高，也有更大的效力。
Septic tanks and other on‐site systems are a common means of disposing domestic wastewater effluent in Ireland. In assessing site suitability, subsoils below the percolation trench have an important role in attenuating pollutants and hence in protecting groundwater. As part of an investigation into the hydraulic performance of treatment systems at four sites in Ireland with different subsoil characteristics, a series of samples were analysed for endocrine‐disrupting chemicals (EDCs), including oestrogens, surfactants and organic oxygen compounds. EDCs were found at all four sites, but only at low concentrations (often below those at which their presence could be confirmed) and generally only in samples known to be percolating effluent. Further research should target oestrogen compounds, as these appear to be present in higher concentrations than the other EDCs and also have greater potency.
