饮用水处理化学污染、外来物质的存在和交付问题可能会影响饮用水质量、电厂可靠性、法规遵从性以及残留物处理和处置实践。这项研究的目的是详细说明处理化学问题，并确定需要改进的领域，以减少与处理化学问题相关的后果。在处理化学品清单、化学品投标规范、预卸载程序和测试以及定期专业测试等领域应用简单的程序建议，将提高服务和饮用水质量的可靠性。包括37个参考文献、表格、图表。

Drinking water treatment chemical contamination, presence of foreignmatter, and delivery problems can affect drinking water quality, plant reliability, regulatory compliance, and residuals handling and disposal practices. The goal of this study was to detail treatment chemical issues and to identify areas for improvement that will reduce the consequences associated with treatment chemical problems. The application of simple procedural recommendations in the areas of treatment chemical inventory, chemical bid specification, pre-unloading procedures and testing, and periodic specialty testing will improve the reliability of service and drinking water quality. Includes 37 references, tables, figures.
