Arsenic & Activated Carbon

In 1986, California voters approved an initiative to address growing concerns about exposure to toxic chemicals. That initiative became the Safe Drinking Water and Toxic Enforcement Act of 1986, better known Proposition (Prop) 65. The act requires the state to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm. This list, which must be updated at least once a year, has grown to include approximately 800 chemicals since it was first published in 1987.

Emerging Chemical Concerns

Many adverse ecological effects have been attributed to pharmaceutical and personal care products (PPCPs) and endocrine-disrupting compounds (EDCs), but it is not clear what risk they pose to human health. In the past, water was known to contain these chemicals, but the exact amount was difficult to quantify. Recently, these chemicals have gained much more attention.

Organic Contaminant Removal With Activated Carbon

Activated carbon is commonly used in point-of-use (POU) and point-of-entry (POE) water applications. Activated carbon is predominantly used to remove organic-based contaminants and inorganic contaminants like free chlorine and monochloramine from water. Other water treatment processes such as reverse osmosis or ion exchange are better suited for other inorganic chemicals that may be present in water.

Surcharge Imposed on All Chinese Steam-Activated Carbon

 

At this point, many of you probably have learned that the U.S. Department of Commerce (DOC) has announced a significant preliminary increase of anti-dumping duties on steam-activated carbon imported from China. Domestic manufacturers can expect to see duties increase from 4.8% to as much as 14 to 228%.

Following the announcement, U.S. Customs and Border Protection will require importers to post a deposit in the amount of the duties.
