BEM 4351, UNIT VIII, ESSAY 2 BEM 4351, Unit VIII, Essay Environmental Protection Agency Environmental Technology Verification Program The Environmental Technology Verification (ETV) program was established by the Environmental Protection Agency (EPA) in 1995 to verify the performance of innovative environmental technologies that can be used to monitor, prevent, control, and clean up pollution (Ashley, et al., 2005). The purpose of the ETV Program is to develop testing protocol and verify the performance of technologies that have the potential to improve the protection of worker health and the environment (Ashley, et al., 2005). Examples of Monitoring Technologies Verified Environmental monitoring accounts for about half of all monitoring technologies that have been verified. Effective verification of monitoring technologies is needed to assess environmental quality and to supply cost and performance data to select the most appropriate technology for that assessment (Ashley, et al., 2005). The Advanced Monitoring System (AMS) Center is partnered with Battelle and verifies the performance of technologies that are commercially available to monitor intentional contamination of public drinking water (Ashley, et al., 2005). The center is currently focusing on verification activities for various important technology areas including ammonia continuous emission monitors (CEMs) and mercury CEMs (Ashley, et al., 2005). Ammonia Sensors Ammonia is a natural and common nitrous agent affecting all vital processes in animal, plant and bacterial cells. In organisms, it is produced by about two hundred enzyme reactions, thus being an essential and harmless metabolite. At high concentrations, ammonia becomes a

Exposure to the eyes, nose, and throat will cause a burning sensation because ammonia is a corrosive, and it has the potential to cause serious injury or death at high concentrations. Agricultural industries produce a significant amount of ammonia emissions from livestock waste, and ammonia sensing technologies verified by AMS measure ammonia concentration in the air. This technology provides a resource for controlling ammonia emissions that are dangerous to health and the environment. Mercury Sensors Mercury is one of the most common, naturally occuring household items that no one knows about. It can be found in items such as thermometers, light bulbs, batteries, and can even be ingested by eating seafood. Metallic liquid mercury is hazardous when it comes in contact with skin. However, liquid mercury can become mercury gas when heated, and them becomes dangerous to the skin, eyes, nervous system, immune system, digestive system, and stomach. Besides mercury CEMs, verification testing categories for which multiple rounds of testing have been conducted include: NOx portable analyzers, optical open-path monitors, portable multigas emissions analyzers, turbidimeters, arsenic test kits, multiparameter water quality probes,
