Rios ABSTRACT. A new mass conservative method for solving the one- dimensional equation of pollutants transport in groundwater, based on the characteristics and finite volume method is derived and discussed. Test results demo st rate his accu- racy and efficiency for transport problems that are dominated by advection. 1. INTRODUCTION. Grounwater pollution due to human activities occurs in a number of ways such as seepage through landfills and waste deposits. The distance that can be covered within a certain time depends on the velocity of flow and the persist an ce of the pollutant. We assume that the fl
