Arsenic
Naturally occurring element that has both inorganic and organic forms
Health Guideline Level (HGL)
0 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
The EPA drinking water standards for arsenic are based on adverse effects to the cardiovascular, pulmonary and liver systems in drinking water with inorganic arsenic, as well as an increased risk of cancer. Long term health effects of total arsenic in drinking water include bladder, GI tract, kidney, liver, lung, pancreas and skin cancer, cardiovascular effects, pulmonary and gastrointestinal effects, ocular, immunological, neurological and reproductive effects. Arsenic found in epidemiological studies include developmental effects, socioeconomic and genotoxicity.
Affected Organs & Systems:
Common Sources
- Present in the earth's crust and is present in the different inorganic forms in minerals and soil
- Arsenic can enter groundwater via the erosion of arsenic-containing mineral and rock deposits in the earth's crust
- Inorganic arsenic enters drinking water through corrosion of arsenic-containing mineral and rock deposits present in the aquifer
- Previously enhanced the environment via past contamination sources remain relevant
- Erosion of natural lead deposits and industrial waste streams can also increase levels of lead in drinking water
How to Remove It
Water filters certified under the following NSF standards are effective at removing Arsenic:
Health Guideline Level
The HGL represents the maximum level that poses minimal health risk based on the latest scientific research. It's often more protective than federal legal limits.
Contaminant Type
Arsenic is classified as a Metals contaminant.
This contaminant primarily affects the nervous-system, developmental, and other systems.
