| Wells
Exceeding the Gross Alpha MCL
of 15 pCi/L
Erosion
of natural deposits of certain minerals
that are radioactive may emit a form of
radiation known as alpha radiation. The
alpha radiation is emitted from both short-lived
and long-lived radionuclides. In the Southern
part of the state, it is probably the
decay of radium and its radioisomers that
result in the alpha radiation.

Wells
Exceeding the Arsenic MCL
of 5 ug/L
Arsenic
can leach into ground water from the erosion
of natural deposits of arsenic, from past
use as a pesticide, and from waste from
glass or electronics production. In New
Jersey, it is known that wells drilled
in Northern New Jersey can contain high
levels of naturally occurring arsenic.
