What Are Nitrates
Nitrates are common contaminants that are typically found in groundwater, soil, and reservoirs. Nitrate (NO3) is a naturally occurring form of nitrogen found in soil. Nitrogen is essential to all life. Most crop plants require large quantities to sustain high yields. Nitrate is a colorless, odorless, and tasteless compound that is present in some groundwater in Michigan.
Health Effects of Nitrates
High nitrate levels in water can cause methemoglobinemia or blue baby syndrome, a condition found especially in infants under six months. The stomach acid of an infant is not as strong as in older children and adults. This causes an increase in bacteria that can readily convert nitrate to nitrite (NO2). Do not let infants drink water that exceeds 10 mg/l NO3-N. This includes formula preparation.
