本powerpoint演示文稿首先简要概述水系统，然后介绍含水层储存和回收（ASR）操作，包括: ASR作为污水处理厂的补充 在高使用期和 在冬季高浊度事件期间； 注射通常从11月到3月 在四口井中的两口，约3.5 mgd； 储存目标为500毫克， 4口井中的3口井的采收率约为6.7 mgd， 100%回收利用地下水权。初步调查包括: 在30天的储存期内监测THM浓度 句号 每四口井的THM每周测量； 从每口井和成品水中采集样本 来自TP；和 存储30天后的时间序列分析（每10天一次）- 分钟（持续1小时）。分析方法包括: 美国环境保护局方法524.2； 毛细管柱净化有机物 GC/MS； 替代方法551.1和552.2（液体萃取） ECD）； 所有这些都提供完整的物种形成； Hach程序10132； 分光光度计上的比色读数； 所有结果报告为氯仿（CHCl3）；和 估计检测限为6微克L-1。研究结果包括: THM浓度似乎与储存有关 体积 在储存期内形成迅速； 消散率表明THM不存在 在储存水中均匀分布； ASR 1和ASR 2中缺乏观察表明存在局限性 现象学； 三卤甲烷的消散似乎不是一个问题 混合/稀释功能（基于地球化学） 数据）； TOC可能是形成的限制因素；和（三角形） 额外的潜在来源表明 TOC/DOC。包括表格、数字。

This powerpoint presentation begins by providing a brief overview of a water system and then provides aquifer storage and retrieval (ASR) operations, including: ASR as a supplement to treatment plant production during high-use periods and in winter during high turbidity events; injection typically from Nov-March at two of four wells approximately 3.5 mgd; storage goal of 500 mg, recovery from 3 of 4 wells approximately 6.7 mgd, 100% recovery with use of groundwater rights. Initial investigations included the following: monitor THM concentrations over a 30-day storage period, with weekly measurements of THM at each of four wells; collect samples from each well and finished water from TP; and, time series analysis after 30-d storage (every 10- min for 1 h). The analytical methodology included: U.S. Environmental Protection Agency Method 524.2; purgeable organic compounds by capillary column GC/MS; alternate methods 551.1 and 552.2 (liquid extraction with ECD); all provide full speciation; Hach Procedure 10132; colorimetric read on spectrophotometer; all results reported as chloroform (CHCl3); and, estimated detection limit of 6 ug L-1. Study findings include the following: THM concentration appears to be related to storage volume; formation occurs rapidly during storage period; rate of dissipation indicates that THMs are not evenly distributed in stored water; lack of observation in ASR 1 and 2 suggests a localized phenomenom; dissipation of THMs does not appear to be a function of mixing/dilution (based on geochem data); TOC probably the limiting factor in formation; and, (triangle) SUVA indicates potential source of additional TOC/DOC.
