EPA has developed a series of Security Product Guides to assist treatment plant operators and utility managers in reducing risks from, and providing protection against, possible natural disasters and intentional terrorist attacks. The guides provide information on a variety of products available to enhance physical security (such as walls, gates, and manhole locks to delay unauthorized entry into buildings or pipe systems) and electronic or cyber security (such as computer firewalls and remote monitoring systems that can report on outlying processes). Other guides present information on monitoring tools that can be used to identify anomalies in process streams or finished water that may represent potential threats. Individual products evaluated in these guides will be applicable to distribution systems, wastewater collection systems, pumping stations, treatment processes, main plant and remote sites, personnel entry, chemical delivery and storage, SCADA, and control systems for water and wastewater treatment systems.
