A study was conducted to evaluate the effect of temperature on the dispersion of 1,2-dibromo-3-chloropropane (DBCP) in soil. The facility of solution of DBCP in water was also investigated. Results of these studies show that the movement of DBCP from an injection site is temperature dependent. These data also indicate that DBCP dissolves readily in water and that dissolved chemical serves to limit the rate of outward dispersion once the liquid DBCP which was added has changed state. The mechanics of DBCP dispersion following soil injection are discussed.
