当评估化学或微生物污染物对环境和饮用沃茨的潜在影响或可能的监管时，关键的第一步是确定污染物是否存在，以及它们的浓度是否可能引起人类或生态健康问题。为此，作为两阶段研究的一部分，对29个饮用水处理厂（DWTP）的水源和处理后的饮用水样本进行了分析，以确定沃茨中是否可检测到化学和微生物成分，其中许多成分被认为是新出现的污染物。在9个一期污水处理厂监测的84种化学品中，有27种在源水中至少检测到一次，21种在处理后的饮用水中至少检测到一次。在第二阶段，这是一个更广泛和更全面的评估，247个化学和微生物分析物进行了测量，在25个污水处理厂，148个检测到至少一次在源水，121个检测到至少一次在处理过的饮用水。检测频率通常与分析物的污染物类别有关，因为药物和人为废物指标往往不常被检测到，而且在处理过程中更容易被去除，而全氟烷基和多氟烷基物质以及无机成分都更常被检测到，总体而言，对处理的抵抗力更强。作为该项目的一部分，收集的数据将用于帮助评估地表水，地下水和饮用水中的不受管制的污染物。
When chemical or microbial contaminants are assessed for potential effect or possible regulation in ambient and drinking waters, a critical first step is determining if the contaminants occur and if they are at concentrations that may cause human or ecological health concerns. To this end, source and treated drinking water samples from29 drinking water treatment plants (DWTPs) were analyzed as part of a two-phase study to determine whether chemical and microbial constituents, many of which are considered contaminants of emerging concern, were detectable in the waters. Of the 84 chemicals monitored in the 9 Phase I DWTPs, 27 were detected at least once in the source water, and 21 were detected at least once in treated drinking water. In Phase II, which was a broader and more comprehensive assessment, 247 chemical and microbial analytes were measured in 25 DWTPs, with 148 detected at least once in the source water, and 121 detected at least once in the treated drinking water. The frequency of detection was often related to the analyte’s contaminant class, as pharmaceuticals and anthropogenic waste indicators tended to be infrequently detected and more easily removed during treatment, while per and polyfluoroalkyl substances and inorganic constituents were both more frequently detected and, overall, more resistant to treatment. The data collected as part of this project will be used to help inform evaluation of unregulated contaminants in surface water, groundwater, and drinking water.
