The water is treated at the well house with
chlorine, potassium hydroxide and poly phosphates. The chlorine
is added as a precautionary measure to ensure the safety of the
water should a problem develop. The chlorine is added for the
same reason we wear seat belts in our automobiles; we do not
expect to be in a car crash, but if we are, there is an added
layer of protection. Potassium hydroxide is added to raise the
pH of the water so the water will be less corrosive. Poly
phosphate is also added to reduce the naturally occurring
corrosive effects of all waters.
The reason we take
measures to reduce the naturally corrosive nature of water is to
reduce the number of leaks in metal piping in the street as well
as your residence and to reduce the potential levels of lead and
copper.
Please review the
annual water quality report for more information on the routine
testing of the water supply.
IRON IN THE WATER
The water we
obtain from our well field in Sutton is crystal clear and
totally free of iron. The majority of our water comes from the
Sutton well field. The secondary well field, known as the
Whitin Well field, is located on the north shore of Meadow
Pond. It is the Whitin well field which has naturally occurring
iron in the water.
Most of the year,
the Whitin well field is used sparingly and the water supply is
basically free of iron. However, in the summer months when lawn
water increases the demand on the system, it becomes necessary
to use the Whitin well field to meet the demand. As such, a
greater percentage of the all the water produced will then be
influenced by the iron from the Whitin wells.
Iron, at the
levels in the water from the Whitin wells has no adverse health
effects. Iron is purely an aesthetic problem in our system.
Iron is a colorless element when initially found in ground
water. It is only when it is exposed to an oxygen molecule that
it is converted to a solid and a visible form (i.e. rust). We
sequester the iron in the water at the Whitin wells using a poly
phosphate. Sequestering means we encapsulate the iron molecule
in an effort to prevent an oxygen molecule from chemically
combining with the iron. The process helps the situation but it
has its limitations.
THINGS YOU CAN DO TO REDUCE THE EFFECTS OF
IRON
The majority of
problems associated with iron involve the hot water system.
Heat is an enzyme to any chemical reaction. When water with
iron enters a hot water tank, the heat will encourage the oxygen
in the water to bond with the sequestered iron molecule to form
the rust we then can see.
In an effort to
reduce the build up of rust, you should periodically flush the
hot water system. This will not only reduce the iron in the
water at times, it will also improve the heating efficiency of
the system. Simple run a hose to waste from the spigot on the
hot water system until the water clears. You may also simply
place a 5 gallon bucket and run the water until it clears. Do
this every six months and you can reduce the concerns associated
with iron in the water.
You may also
choose to install a simple “cartridge type” filter on the water
pipe as the water enters the house. This type of filter will
remove naturally occurring sediment in the water and is easy to
maintain. The installation will only require some simple
plumbing and the cost to maintain the system is inexpensive and
can be done by anyone.
If a company ever
tries to sell you a water softener or a chemically involved
treatment system, you will be wasting your money.
If you have
stained fixtures or clothes due to iron in the water, you may
wish to become familiar with commercial products which are
designed to remove iron stains such as “iron out” or “red-B
gone”.
REGARDING DISCOLORATION OF WATER
The reason
that the water can be discolored at times is due to the fact
there is naturally occurring iron in the water which originates
from the well field located on the shores of Meadow Pond. The
most important variable associated with iron is that it has
no adverse health effects at the levels found in drinking water.
However, iron does cause aesthetic problems which is the basis
for your understandable concern.
Iron, as it is withdrawn from the groundwater, is in a liquid
form and is colorless. It is only when
the iron molecule is exposed
to an oxygen molecule that it turns to iron oxide ( rust) and it
is now visible. We treat the water at the source ( well field)
by using a process which encapsulates the iron molecule so that
the oxygen molecule cannot combine with the iron. The treatment
improves the water quality, however, the treatment process is
not 100% effective.
Fortunately,
we also have a well field in Sutton where the majority of our
water comes from and is blended with the water we obtain from
the well field on the banks of Meadow Pond. The water from
Sutton is totally free of iron and is crystal clear. The
combination of the two waters produces a water that is generally
quite good. However, the accumulation of the iron in the water
mains and hot water tanks does cause the discolored water on
those occasions when disturbance of the mains or hot water tanks
occur.
HELPFUL ADVICE
The following are some measures that each homeowner can
take which will reduce the adverse aesthetic effects of the iron
in the water:
- FLUSH THE HOT
WATER TANK - The majority of
concerns associated with the discolored water are associated
with hot water. This is due to the fact that heat is an
enzyme to any chemical reaction and the heat converts the
liquid iron to the solid iron which we can then see. Every
few months, flush the hot water tank by opening the spigot
and running water to waste through a hose or into a bucket
until the water clears. This will remove the accumulated
iron from the bottom of the hot water tank which will help
to keep the water clear while also improving the heating
efficiency.
- USE IRON OUT OR
EQUIVALENT – Become familiar
with the product called Iron Out which is used to clean iron
stains or remove stains from clothes. Iron out is available
at most hardware stores. There are also other products
which are designed to reduce the effects of iron.
- INSTALL A
CARTRIDGE TYPE FILTER – There
is a simple “cartridge type” filter that can be installed on
the water line as it enters the house for a very reasonable
cost. The maintenance of the simple filters is very easy
and very inexpensive. The initial installation can be
accomplished for approximately $55.00 in parts and then some
time to put the plumbing together. The cartridges remove
some of the iron if it is already in the solid form.
There is no justification for a
water softener type filter or a filter system which uses any
chemicals in the process of treating the water. Please do not
waste your money should anyone try to sell you such a filter. |
