Environmental Profile
WATER SOLUBILITY: 15000 ppm (pH 7)

Fate in :
Tier 1 drinking water modelling studies using FIRST for surface waters and SCI-GROW for ground water, produced estimated maximum concentrations of 0.2 - 0.22 ppb in a chronic scenario. These values are less than the worst case calculated acceptable level of 3.95 ppb for residues in drinking water based on a child's chronic aggregate exposure.
