Three measurements of a pollutant upgradient of a landfill yield a mean of 15.4 mg/L

Three measurements of a pollutant upgradient of a landfill yield a mean of 15.4 mg/L and a standard deviation of 2.8 mg/L. Five measurements made downgradient of the landfill result in a mean of 29.1 mg/L and a standard deviation of 7.4 mg/L. Is it safe to conclude that the landfill contributes to increasing the pollutant level in the groundwater?
