Which regulation limits human exposure to harmful organisms like Cryptosporidium?

• A. Ground Water Rule (GWR)
• B. Interim Enhanced Surface Water Treatment Rule (IESWTR)
• C. Total Coliform Rule (TCR)
• D. Surface Water Treatment Rule (SWTR)

Answer: (B)

The Interim Enhanced Surface Water Treatment Rule (IESWTR) is significant in limiting human exposure to harmful organisms, particularly Cryptosporidium, a protozoan that can cause gastrointestinal illnesses. This regulation was established to address the actions necessary for enhanced treatment and monitoring of drinking water sources that contain surface water or groundwater influenced by surface water. The IESWTR emphasizes the need for improved treatment processes, such as filtration and disinfection, to ensure that water supplies are adequately protecting public health from harmful microorganisms. It incorporates specific requirements for water systems, which include demonstrating the effectiveness of treatment methods to remove or inactivate pathogens like Cryptosporidium. In contrast, the other regulations mentioned either target different aspects of water quality or pathogens, or focus on general criteria for drinking water but do not specifically address the unique challenges posed by organisms such as Cryptosporidium in the same comprehensive manner as the IESWTR.
