Arsenic is a known human carcinogen linked to cancers of the skin, bladder, lung, kidney, and liver. Long-term exposure can cause skin damage including color changes and lesions. Arsenic exposure is associated with cardiovascular disease, diabetes, and neurological effects. Studies have shown links between arsenic exposure and developmental effects in children, including reduced IQ and learning disabilities.
Erosion of natural deposits in the earth; runoff from orchards; discharge from glass and petroleum refineries
Based on our analysis of EPA Safe Drinking Water Information System (SDWIS) data and local water utility reports,arsenic has been detected in 87 Florida water systems. The average level across all tested cities is 15% of the EPA Maximum Contaminant Level (MCL), with the highest detection at 48.3% of the limit.
The EPA set the arsenic MCL at 0.010 mg/L (10 ppb) in 2001. The EPA MCL for arsenic is 0.01 mg/L. This limit is set to protect public health based on available scientific evidence about the contaminant's health effects.
87 Florida cities have arsenic detected in their water supply. All tested cities are within EPA safety limits.
Increased cancer risk (skin, bladder, lung), skin damage, cardiovascular disease, diabetes. The most vulnerable groups include children and people with cardiovascular conditions.
The most effective methods for removing arsenic include Reverse Osmosis, Adsorption Media (Iron-Based), Distillation. Look for filters certified by NSF/ANSI for arsenic reduction.
The EPA Maximum Contaminant Level (MCL) for arsenic is 0.01 mg/L.The EPA set the arsenic MCL at 0.010 mg/L (10 ppb) in 2001.
Recommended filtration methods for arsenic removal:
Removes 90-95% of arsenic
Specifically designed for arsenic
Effective for all forms of arsenic
