Abstract

The use of mercury as a material for bonding and separating gold with sand in gold mining has
the potential to contaminate ground water and river water. In this study, the distribution of mercury parameters
from gold mining occurred in Pelawan river, Sarolangun regency, Jambi Province. To determine contaminants
flow, In this study mathematical modeling mercury was carried out using 1-dimensional analytic model based on
advection-dispersion equation in surface water. The concentration of mercury in water is measured 3 times for
calibration and model validation. From the measurements at some point, it is known that the Pelawan river is
contaminated with mercury, the mercury value obtained is 0.007 mg / l, this value is far past the quality standard
based on Government Regulation No.82 of 2001 on the management of water quality and water pollution
control. Mercury simulation showed that the longer time (t), a constant input of pollutants that create greater
pollution load. As a result, the concentration of pollutants in the larger t will decline at a greater distance. The
resultsof mercyry simulation with
k = 0,22/day showed that the mercury model is quite close to the mercury
concentration observations.
