"Arsenic is a known carcinogen, increasing the risk of cancer even at very low concentrations. Arsenic occurs naturally in many groundwaters throughout the USA, less commonly in surface waters. With the recent passage of new limits restricting arsenic levels in potable water, many public water supplies require arsenic reduction prior to use. Although there are many treatment technologies available for arsenic reduction, one of the simplest methods is to use an arsenic selective adsorbent media. This type of system is well suited for residential systems as well as larger commercial and municipal systems, requiring little or no maintenance and only periodic monitoring. Suzhou X Chemical manufactures a unique arsenic selective adsorbent resin hybrid BAR-1FD. It is WQA certified to meet the ANSI/NSF 61 standard for potable water."
