- PA DEP
- Act 2 Statewide Health Standards
- CAS 14797-65-0
For NITRITE NITROGEN, DEP's Statewide Health Standard tables print 1,000 ug/L for residential groundwater in a used aquifer with TDS up to 2500.
- 1,000ug/L 1000 R Table 2: Medium-Specific Concentrations (MSCs) for Inorganic Regulated Substances in Groundwater Used Aquifers, TDS ≤ 2500
These are the Pennsylvania Department of Environmental Protection's published values for NITRITE NITROGEN, from its Statewide Health Standard tables. DEP's page says the tables present the standards published November 20, 2021. Each value is shown as the agency prints it, with the same number written out beside it where that reads differently.
