🧬 NDMA Photolysis (254nm Direct UV Photolysis, Quantum Yield Phi=0.30, 2.0-Log Reduction)

Potable Water NDMA Direct UV Photolysis Calculator

Model direct photochemical photolysis kinetics of carcinogenic N-Nitrosodimethylamine ($NDMA$) at 254nm ($Phi = 0.30 ext{ mol/Einstein}$ quantum yield): calculate required UV fluence dose ($>800 ext{ mJ/cm}^2$) achieving $2.0 ext{-log}$ ($99%$) NDMA destruction under California DPR guidelines, and public health water yields.
