Arsenic Occurrence in New Wells
August 2008 – July 2013
Arsenic Concentration
>2 µg/L <10 µg/L
>10 µg/L
2 micrograms per liter (µg/L)
is the lower detection limit for
arsenic used by most laboratories.
10 µg/L is the Maximum Contaminant
Level (MCL) for arsenic and is the
national enforceable standard for
community water supplies.
Each dot represents a single well. Wells which were sampled and had less than 2 µg/L arsenic
are not shown on this map.
