• Why every 3 to 5 years?
•Arsenic is a known human carcinogen.
•10% of all wells in Maine above 10 ppb arsenic.
• Maine has hotspots.
• This can be fixed.

• Lower well water guidance from 20,000 pCi/L to 4,000 pCi/L
• Emphasize air treatment at 2 pCi/L.

• 5% of all wells in Maine above 20 ppb.
• Also find uranium hot spots.
• Health effect of concern is kidney effects

• EPA has an MCL of 4 mg/L and a secondary MCL of 2 mg/L.
• NAS decided that 4 mg/L is not protective and recommended EPA re-evaluate 2 mg/L.
• Our MEG is based on dental fluorosis.
