What is arsenic?
Arsenic is a semi-metal element in the periodic
table. It is odorless and tasteless.
•
How does arsenic get into my drinking
water?
Because it occurs naturally in the environment and
as a by-product of some agricultural and industrial
activities, it can enter drinking water through the
ground or as runoff into surface water sources.
•
Water is a universal solvent and suspends the
arsenic in it easily.
Nitrates
•
One of most common contaminates of ground
water.
•
can cause methemoglobinemia or "blue
baby" disease.
