Health Effects. Health effects of nitrate in drinking water are most significantly linked to methemoglobinemia, also known as âblue-baby syndrome.â Baby formula mixed with nitrate-contaminated water exposes infants to nitrate. In infants 0-4 months old, the nitrate is converted to nitrite in the infantâs stomach.aturally, knowing the original nitrate concentration in the water is important. If nitrate-nitrogen levels are extremely high (greater than 110 mg/l) up to 90 percent may be removed. Unfortunately, remaining nitrate-nitrogen may still result in drinking water that exceeds the standards of 10 mg/l nitrate-nitrogen.
