1. A process for removing trihalomethane precursors from water containing said precursors which comprises treating the water, at a rate of from about 1 to about 25 milligrams of resin per liter of water, with a fine-particle-size anion exchange resin having an equilibrium parameter of Ke =6×

  • 105 cm3 /g or greater, a kinetic parameter of Kk =6 sec-1 or greater, and a combined value of Ke /105 +Kk of about 13 to about 22, and subsequently removing the resin from the water.
