Compliance with U.S. Government Standards
In the United States, the Safe Drinking Water Act is the fundamental federal law ensuring the quality of drinking water. This act has required the U.S. Environmental Protection Agency (USEPA) to develop standards and regulations to increase protection of drinking water against contaminants and tighten controls governing chemical disinfection byproducts. The regulations apply to the processing of surface water, groundwater, industrial and municipal wastewater, secondary effluent, and salt water for direct and indirect potable use.
Pall Aria™ systems are designed to produce water that complies with the USEPA regulations listed below.
US EPA Regulations Governing Water Treatment
|Surface Water Treatment Rule
||Water from surface sources, or under the direct
influence of surface water, must meet the mandated limits for Cryptosporidium, Giardia lamblia, bacteria, turbidity, and viruses in drinking water.
- The Pall Aria system has achieved a >6 log reduction in Cryptosporidium and Giardia lamblia and a >4 log reduction in coliform bacteria.
|Disinfection Byproduct Rule
||Water that is chemically disinfected for drinking must comply with maximum contaminant levels for disinfection byproducts.
- The Pall Aria system, with appropriate pretreatment, helps ensure compliance with the Disinfection Byproduct Rule and has tested well below regulatory limits for THM and HAAS.
|| Any water distributed to the public must contain no more than 10 μg/L of arsenic.
- The Pall Aria system has demonstrated a reduction of arsenic to undetectable levels (<2 ppb).
The Pall Aria system has received the following certifications.
- Testing and certification by NSF to NSF International Standard 61.
- Independent testing and certification by NSF International Drinking Water Systems Center for arsenic reduction to <2 ppb.
