New nitrate method eliminates matrix interferences and hazardous waste generation
After review of validation data, the U.S. Environmental Protection Agency (EPA) has approved the use of Systea Scientific’s new non-hazardous nitrate method for use in measuring the levels of contaminants in drinking water and determining compliance with national primary drinking water regulations.
The EPA determined that the method is “equally effective” as current Safe Water Drinking Act (SWDA) methods for nitrate. The new method meets all requirements at 40 CFR Part 141 for measurement of nitrate and nitrite singly or combined in drinking water.
The new “green” method eliminates problems associated with nitrate analysis such as matrix interferences, poor reproducibility and recovery, hazardous waste generation and exposure of laboratory personnel to carcinogenic compounds such as and cadmium used in method 353.2 Rev 2.0.
