Ion Exchange Resins for Groundwater Contaminant Removal

purolite resins effectively remove perchlorate contamination from drinking water

Perchlorates are natural salts derived from perchloric acid and enter the environment through industrial activities—but are also naturally occurring. Perchlorate in drinking water supplies is a growing health concern as it can damage the thyroid gland that controls human growth, development and metabolism. It is particularly detrimental to developing fetuses and young children as it can affect brain development and cause hearing loss, speech delays or impairment, as well as have other effects on motor skills.

Purolite is committed to providing clean, safe drinking water. We work closely with communities and municipalities throughout North America and Europe to deliver perchlorate-free drinking water.

Purolite's David LaRose is an expert on removing perchlorate contamination from drinking water through ion exchange technology. He has written a paper that was published in the USA and China entitled Ion exchange for Perchlorate Removal that reviews the sources, effects and regulations governing this contaminant, as well as the effectiveness of ion exchange technology for removing it from drinking water. 

Dave also participated in a WaterOnline Webcast that discusses the use of ion exchange resin technologies for removing contaminants from potable and ground water—including perchlorate.

Some popular ion exchange treatment options for perchlorate include Purolite® A530E and Purolite® A532E, which are both certified by the WQA to NSF/ANSI-61 for drinking water system components. Your local technical sales expert will be happy to assist you with the best treatment solution for perchlorate contamination.

The U.S. Environmental Protection Agency (EPA) has developed a technical fact sheet for perchlorate that provides an overview of what it is, where it comes from, environmental impacts, and  effects on human health.

Currently, perchlorate is regulated under the Safe Drinking Water Act in the USA and is considered in the WHO Guidelines for drinking-water quality.
