Question
Is there any specification on how much arsenic the GWV High Capacity Groundwater Filter removes?
Summary
Arsenic removal using the GWV High Capacity Groundwater Filter
Answer
The manufacturer makes no specification on the amount of arsenic the GWV High Capacity Groundwater filter (catalog number/order code 2670500) removes.

The only way for an end user to obtain this information would be to test it themselves. End users may also want to go to the EPA to get recommendations on the types of filters they should be using for their process.

These filters are meant to remove suspended materials (including metals) while allowing the dissolved materials to pass through. These are not intended to clean up water samples by removing all metals. That would have to be done through a chemical treatment (such as a flocculation step before the filtration). These filters are meant to remove suspended particulates in a groundwater sample to that the dissolved metals can be analyzed with minimal matrix interference.

The certification comes from the EPA methods 200.7 and 200.8 which are the two main methods by which metals are analyzed. This is important because users are typically trying to detect sub-ppb levels of metals and trace amounts found anywhere within the sampling train can bias the results.

More information on the specifications of these filters can be found in the article titled, " What are the specifications of the Filter, GWV High Capacity Groundwater (catalog number 2670500)?".
