The Henry's Law constant for chloroform is 3.67X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that chloroform is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 3.5 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 4.4 days(SRC). Three laboratory studies of the evaporation of chloroform from water gave half-lives of 3-5.6 hrs with moderate mixing conditions(3-5). Chloroform volatilization constants were estimated in chilled (4 deg C) and boiled (100 deg C) water to be 0.88/hour and 1.50/hour, respectively(6). Estimated volatilization constants in experiments at 25 and 30 deg C ranged from 0.055/hour to 0.411/hour depending on the width and liquid level in the glass(6). Chloroform's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Chloroform is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 197 mm Hg(7).

A soil sorption study was conducted on chloroform in three distinctly different soils(1). Soils used were from Missouri (composed of 11.4% sand, 52.7% silt, 33.4% clay, 2.4% organic matter, at pH 6.9), California (composed of 45.1% sand, 35.2% silt, 21.7% clay, organic matter 1.7%, at pH 8.1), and Florida (composed of 91.7% sand, 6.3% silt, 2.0% clay, 1.6% organic matter, at pH 4.7)(1). The ratio of the amount of contaminant adsorbed in micrograms per gram of soil to the equilibrium concn in ppm was used to calculate a Kd value of 2.133 in the Missouri soil, 1.941 in the California soil, and 1.763 in the Florida soil(1). These values correspond to a Koc value ranging from 153-196 based upon the relationship between Kd and Koc(2). Chloroform is adsorbed most strongly to peat moss, less strongly to clay, very slightly to dolomite limestone and not at all to sand(3). The Koc values measured for 2 soils was 34; 3 other soils with the lowest organic carbon content in the same study gave no appreciable adsorption(4). Field experiments in which chloroform was injected into an aquifer and the concn in a series of observation wells determined, demonstrated that chloroform is very poorly retained by aquifer material (retardation factor 2-4), less so than other C1- and C2-halogenated compounds studied(4-5). Laboratory percolation studies with a sandy soil gave similar results (retardation factor <1.5)(6). Chloroform was reported to have a Koc of 65(7), 55(8), 47(9) and 34(10). According to a classification scheme(11), these Koc values suggest that chloroform is expected to have very high to moderate mobility in soil.
