Nitrite-N cleanup levels by state
- CAS 14797-65-0
- 3 states
CAS 14797-65-0 is in the cleanup-level tables of 3 states in this handbook: Florida (Nitrite), Pennsylvania (NITRITE NITROGEN) and Texas (Nitrite-N). Each state's numbers are below as its agency prints them. The states run different programs and do not define their values the same way, so a number from one is not the same measure as a number from another. A state that lists the substance under another CAS number, or without one, is not shown here.
Florida
- FL DEP
- Chapter 62-777 CTLs
- February 2005
For Nitrite, DEP's cleanup target level tables print 1,000 ug/L as the groundwater criterion and 8,700 mg/kg for residential direct exposure to soil.
- 1,000ug/L 1000 Groundwater Criteria Table I: Groundwater and Surface Water Cleanup Target Levels
- 8,700mg/kg 8700 Direct Exposure - Residential Table II: Soil Cleanup Target Levels
Pennsylvania
- PA DEP
- Act 2 Statewide Health Standards
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
Texas
- TCEQ
- TRRP Tier 1 PCLs
- February 6, 2025
For Nitrite-N, TCEQ's Tier 1 table prints 8,000 mg/kg for TotSoilComb and no value for GWSoilIng (residential soil, 0.5 acre source area), and 1 mg/L for GWGWIng (residential groundwater).
- 8,000mg/kg 8.0E+03 TotSoilComb Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- ─ GWSoilIng Table 1: Tier 1 Residential Soil PCLs 0.5 acre source area
- 1mg/L 1.0E+00 GWGWIng Table 3: Tier 1 Groundwater PCLs - Residential and Commercial/Industrial Residential
