Why Test for Nitrates?
Nitrogen is essential for all living things as it is a principal component of protein.  However, an excessive concentration of nitrate-nitrogen in drinking can be hazardous to health, especially for infants and pregnant women.

How much nitrate in drinking water is too much?
The Environmental Protection Agency (EPA) has set 10 parts per million (ppm) as the Maximum Contaminant Level for public works water systems.

How does nitrate get in the water?
Common sources of nitrate in groundwater are fertilizers, septic systems, livestock waste, and naturally occurring nitrate in the soil.

What if your reading has high nitrates?
If an unacceptable nitrate level is found in your drinking water, do not boil the water.  Boiling water does not eliminate nitrate.  It causes some of the water to evaporate, which increases the concentration of nitrate in the remaining water. Several treatment methods are available for treating drinking water with high nitrates.

This process involves heating the water to boiling and collecting and condensing the steam by means of a metal coil.  Most impurities remain in the heating tank.  Nitrate reduction of up to 99% can be obtained through this process.

Reverse Osmosis
Pressure is applied to impure water forcing it in a reverse direction through a membrane.  As the water passes through, the membrane filters out most of the impurities.  According to manufacturer’s literature, 85 to 95% of the nitrate can be removed by this process.

This process utilizes the principle that impurities in water consist of chemical ions, each containing a small electrical charge.  The water is passed through a treatment tank filled with a bead like resin.  The resin contains the opposite charge of the impurity to be removed.  Ions of opposite charge are attracted to the resin and will remain with the resin as the water passes through the unit.  It is usually necessary to soften water before it passes through the deionization unit.

Bottled Water
An alternative to treating your well drinking water is bottled water.   Be advised that eh Food and Drug Administration does not regulate all bottled water.  A high percentage of bottled water is simply filtered or treated tap water.  Bottled water rules allow higher levels of many contaminants, with more lenient requirements for filtration, testing and reporting.
