Arsenic is a metal that occurs both naturally and artificially in the soil and groundwater. Artificial sources include treated wood, metals, pharmaceuticals, manufacturing waste, petroleum refinement waste, and other sources. Natural arsenic sources consist mainly of volcanic rock and activity*. Arsenic finds its way into our drinking water supply through the gradual flow and movement of soil and water.

Arsenic is a human carcinogen and is also known to cause cancer, vascular and nervous system disorders. According to public health data, Arsenic enters the body primarily through the mouth while skin absorption of arsenic is not generally a health consideration. UC Berkeley research concludes that arsenic is one of the highest naturally occurring cancer risks ever reported. The EPA maximum contaminant level is 10 parts per billion (ppb) down from the previous standard of 50 ppb.

Arsenic comes in two forms and you can have one or both in your water:
Arsenate V – inorganic
Arsenite III – organic

ARSENIC can be present in both private wells and municipal water supplies above the EPA 10 ppb Mcl.

• Arsenic is odorless and tasteless and water must be tested to determine the level of arsenic present.

Boiling water increases the concentration of arsenic and does not remove it from the water.

The ERO 350R Reverse Osmosis System by Ecowater Systems is certified to remove over 99% of arsenate V from your drinking water. The ETF 2100 AS Arsenic filtration system with patented MetSorb arsenic remediation media effectively reduces both arsenic V & III from the household water to safe levels.

*Due to the Mt. St. Helens volcanic activities over recent years, increasing levels of arsenic have been detected in both private and municipal water supplies in the SW Washington area.

We offer arsenic testing as part of our on-site anaylsis
