How Much has Nitrogen Contamination Increased?
Over the decades the use of Nitrogen fertilizer to assist agricultural production has accelerated. Since the late 1940’s , consumption of fertilizers for agricultural use has increased about five hundred percent (500%) . Some of this increase has been due to over-application of the suggested amounts which are needed to improve fruit & vegetable production. These excess amounts have resulted in runoffs of these chemicals and they have found their way into the ground water, rivers, streams, reservoirs, and lakes. Many people have observed these effects as green algae bloom which can been found in lakes and stagnant bodies of water, and even shows up in satellite photos which detail the plumes of algae found exiting into the oceans and are easily seen in the Gulf of Mexico.
This increase in Nitrogen applied to the land ultimately infiltrates our drinking water sources. When Nitrogen breaks down chemically it ends up as Nitrates which exist in a vast majority of our rivers, lakes, and underground water sources, primarily in agricultural areas. Municipal water utilities are regulated by the US Environmental Protection Agency (EPA) and are mandated to have no more than 10mg/liter (milligrams/liter) of nitrate/nitrogen concentration, which is considered to be an acceptable limit.
Rural populations, however, obtain most of their water from underground wells, and these water sources are not subject to federal or local government oversight.
What Nitrogen Levels are Acceptable?
The minimum concentration level (MCL) of 10 mg/L is sometimes slightly exceeded in municipal water treatment, because of the excessive costs to remove it. In the main ,however, it will typically be in the range of (2-10 mg/L). In rural environments, and due to the water runoff from agricultural lands, the level may end up being 3-10 times higher than the government specified Minimum Concentration Level.
Many health studies have pointed to the fact that increased Nitrogen/Nitrate consumption may be contributing to a variety of very unfavorable medical conditions including diabetes, thyroid problems and possibly a higher risk for cancerous diseases. Persons who are concerned about these negative effects should seek out reliable medical scientific studies reflecting the problems with excess Nitrates in our food and drinking water supplies. Check with your local water system provider to see what Nitrogen levels are acceptable.
How can I Find Out the Levels of Nitrogen/Nitrates in My Water Supply?
If your are on a municipal water system, contact them and see what testing they have done, and how you might be able to see the results. Some municipalities publish this information in newsletters or annual summaries or have it available on-line.
If you are unsure of your personal exposure to Nitrogen/Nitrates and you are on a well-based water source, or other non-municipal water system, you may wish to avail yourself of Nitrate and Nitrite Nitrogen Water Test Strips that are commercially available and will help you to identify elevated levels of Nitrogen/Nitrates in your drinking water.
How does all Nitrogen that I Ingest Add UP?
It should be noted, that the total of all Nitrogen/Nitrates in your body will be the sum total of these chemicals found in your drinking water, in the food that you eat, and in in some types of prescription drugs. Minimizing all, or any, of these sources may improve your health and wellness.
