Ground
Water Treatment
For
many years, municipalities providing “city”
water needed only crude filtration and disinfection treatments
to render water “safe and fit” for human consumption.
Well water was often the main source. In the scramble
to source sufficient water for growing urban populations,
municipalities have had to turn to less desirable ground
water sources to fill the pipes. Many of these sources
contain water from aquifers that have been long contaminated
with agricultural run off and mining seepage and even
naturally occurring contaminants such as arsenic,
radium, uranium,
heavy metals as well as man made contaminants such as
industrial wastes, solvents, more heavy metals and higher
dissolved salt levels. Newer EPA standards which are considered
to be more “protective” have also reduced
the MCL (maximum contamination levels) once considered
safe and forced many sources once considered as safe to
now be treated.
Fortunately,
our technology and methods of reducing some of these contaminants
has become very selective, facilitating the removal of
many of the once hard to remove species. These techniques
can apply to the private well owner as well. The same
treatment available to municipalities for removing perchlorates,
arsenic, chrome, uranium,
radium and nitrates
can also be “miniaturized”
for the individual home owner.
