A composition for melting ice and snow includes granular particles, preferably made of urea, the particles being coated by a mixture of an antifreeze composition and a nitrate inhibitor. The antifreeze and nitrate inhibitor are provided in liquid form, and the liquid mixture is sprayed or otherwise coated onto the particles. The composition provides an improved ice-melting material while minimizing environmental damage due to leaching of nitrates into ground water reservoirs. |
