Not so many years ago, my brother-in-law, a Nebraska farmer, made a discovery. The well from which his family pulled their drinking water, a source that had served his family for generations, was polluted from nitrates. The pump house was located near their home on the side of a hill. Near the top of the hill and for hundreds of acres beyond, were the contoured, non-irrigated fields where he grew corn one year, soy beans the next. To maintain productivity and following fertilizer company directions, he had spread nitrogen supplements in a huge, single dose, year after year.
The practice didn’t cost him his water supply. But it did cost him a hefty chunk of change to put in an expensive water purification system. Luckily, his young children were none the worse for it. But it’s common knowledge that nitrates in water cause blue baby syndrome or methemoglobinemia a disease that interferes with the blood’s ability to deliver oxygen where it’s needed. Methemoglobinemia can also affect adults who have digestive problems that don’t allow them to break down nitrates in the gastric system. Nitrates are also linked to some cancers. (more…)
