Arsenic occurs naturally in soil and minerals and may enter the air, water, and land from wind-blown dust and may get into water from runoff and leaching. Arsenic cannot be destroyed in the environment. It can only change its form. Many common arsenic compounds can dissolve in water. Most of the arsenic in water will ultimately end up in soil or sediment.
Drinking water is the main source of human exposure to arsenic. Some people who drink water containing arsenic in excess of the MCL over many years could experience skin damage or problems with their circulatory system, and may have an increased risk of getting cancer. Long-term exposure to arsenic in drinking water is associated with multiple health problems.
- Arsenic is a known human carcinogen linked to cancers of the skin, bladder, kidney, liver, and lung.
- Arsenic has been shown to cause vascular disease (loss of circulation in the limbs) and skin abnormalities (changes in skin texture and color).
- Some researchers have found evidence that arsenic can disrupt the immune and endocrine systems, and may be related to Type-2 diabetes.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Arsenic levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Arsenic levels were detected in your water sample but do not exceed the maximum contaminant level.
