在乔治亚州洛克代尔县的布莱克浅滩水库开展了一项湖泊监测项目，以收集、分析和评估春季和秋季周转事件之间的湖泊水质数据，以确定铁和锰等问题成分的来源。监测项目的主要目标是描述供水蓄水的水质，以设计湖内曝气设施，该设施是乔治亚州洛克代尔县洛克代尔水资源（RWR）水处理厂（WTP）的一部分。 具体而言，湖泊监测项目旨在评估湖泊的空间和时间水质，这对于确定湖内曝气设施的规模和选址是必要的。此外，监测计划将提供有价值的数据，以确定流出排放的最佳深度，从而将水处理厂的处理要求和下游环境影响降至最低。2000年2月至9月进行了湖泊监测。在湖中建立了三个采样点。选择这些采样点是为了给出水库沿其主要流动轴的垂直和纵向剖面。 温度和溶解氧以1英尺深的间隔在现场测定，以更好地确定热分层。其他参数的采样间隔为5英尺。分析样品的以下参数:碱度；浑浊度；氯需求；总铁；总锰；硫化物；氨硝酸盐；和总磷。本文总结了湖泊监测数据分析。此外，还对湖泊曝气要求进行了分析，并讨论了拟议的湖泊曝气设施，以及湖泊曝气对水处理成本和湖泊水质的预期效益。 包括表格、数字。

A lake monitoring program was conducted at Black Shoals reservoir in Rockdale County, Georgia, to collect, analyze, and evaluate lake water quality data between the spring and fall turnover events to identify source(s) of problematic constituents such as iron and manganese. The primary goal of the monitoring program was to characterize the water quality of the water supply impoundment for design of in-lake aeration facilities that are being proposed as part of the Rockdale Water Resources (RWR) Water Treatment Plant (WTP), Rockdale County, Georgia. In particular, the lake monitoring program was designed to assess the spatial and temporal water quality in the lake, which are necessary for the sizing and siting of in-lake aeration facilities. In addition, the monitoring program will provide valuable data to determine the optimal depth of outflow releases to minimize treatment requirements at the WTP and downstream environmental impacts. Lake monitoring took place from February through September, 2000. Three sample points were established in the lake. These sampling points were selected to give both a vertical and longitudinal profile of the reservoir along its primary flow axis. Temperature and dissolved oxygen weredetermined in the field at 1-foot depth intervals to better define thermal stratification. Sampling for other parameters was conducted at 5-foot depth intervals. Samples were analyzed for the following parameters: alkalinity; turbidity; chlorine demand; total iron; total manganese; sulfide; ammonia; nitrate; and total phosphorus. This paper summarizes the lake monitoring data analysis. In addition, an analysis of lake aeration requirements is presented, along with a discussion of proposed lake aeration facilities and anticipated benefits from lake aeration on water treatment costs and lake water quality. Includes tables, figures.
