Recommendations officially state the limit for nitrates at 10 mg/L. Adults of higher order animals like fish (and humans) have evolved metabolic pathways which neutralize nitrate quite efficiently. The EPA Maximum Contaminant Level is: 10 ppm (parts per million) or mg/L (milligrams per liter) nitrate-nitrogen or, if expressed as nitrate, 45 ppm. 2018 Drinking Water Standards and Advisory Tables. What should I do? These figures also may be reported in ppm (parts per million), which is equivalent to mg/l. The MCLG for nitrates has been set at 10 parts per million (ppm), and for nitrites at 1 ppm, because EPA The results showed nitrate levels between 200-450 ppm. That’s because when you boil water, some of it evaporates, so you’re left with the same concentration of contaminants in a smaller amount of water. The 1990 EPA National Survey of Drinking Water Wells found that approximately 57 percent of the private wells tested contained detectable levels of nitrates. … Newborn babies can’t handle the nitrates, but adults are fine with it. Their presence in groundwater is generally associated with septic systems, confined animal feeding operations, or fertilizer use. EPA updates the tables periodically. Nitrates can be found in drinking water supplies. least once a year. The Safe Water Drinking Act of 1974 set forth standards that demanded states guard water supplies to avoid contamination by dangerous levels of foreign bacteria, chemicals, and substances. This law requires EPA to determine safe levels of chemicals in drinking water which do or may cause health problems. Be sure you know which value is reported for your water sample. In the United States the EPA, under the authority of the Safe Drinking Water Act (SDWA), has set the Maximum Contaminant Level Goal (MCLG) for total nitrate/nitrite at 10.0 mg/L and for nitrite at 1.0 mg/L (measured as nitrogen, N). However, in areas where the drinking water is contaminated to a level of 50 ppm)—five times the MCL for nitrate nitrogen—drinking water may supply as much as half of a person’s total daily intake. This is the health-based goal at which no known or anticipated What if I use public water? Nitrate levels are commonly provided in lab reports in one of two ways, either as NO3-N or NO3. Protecting Your Drinking Water. Compare your well-water test result to the drinking water standard set by the United States Environmental Protection Agency (EPA). These sources of nitrate contamination are more associated with rural settings, and are often subjects of drinking water source protection programs . Here are Fact sheets on nitrate in drinking water. Although private well owners are not required to meet these standards, they do serve as a reference for safe drinking water. This means the nitrate levels actually “increase” slightly. These non-enforceable levels, based solely on possible health risks and exposure, are called Maximum Contaminant Level Goals. This document summarizes EPA's drinking water regulations and health advisories, as well as reference dose (RFD) and cancer risk values, for drinking water contaminants. Drinking water generally accounts for 5 to 10 percent of the nitrates that people consume. Any volume over this level is considered unsafe and must be dealt with accordingly. set standards for nitrate levels in public drinking water systems. The only health issue in humans with levels of nitrate above 220 ppm in drinking water is blue baby syndrome. I have more than 10 PPM of nitrate in drinking water. Your well-water is nitrate-safe if the nitrate level is 10 ppm or less (also written as 10 milligrams per liter (10 mg/L)). “A nitrate level of up to 3 ppm in Well water is generally believed to be naturally-occurring and safe for drinking”.
