Water Treatment
Water treatment methods used to eliminate or reduce acidity and
heavy metals precipitation from impacted waters can be grouped into
two types. One method is called active
treatment. Active treatment involves neutralizing acid-polluted
waters with alkaline chemicals (i.e. lime). However, the chemicals
are expensive and the treatment facility is expensive to construct
and operate. The second method is called passive
treatment. This technology involves the construction of a treatment
system that employs naturally occurring chemical and biological
processes which aid in acid mine drainage (AMD) treatment and require
little maintenance. The most common passive treatment technologies
are constructed wetlands and anoxic limestone drains. The water
treatment information found in this section of the tech guide is
separated into active and passive treatment.
