What is a ground water source under the direct influence of surface water?
• A ground water source under the direct influence of surface water is defined as any water beneath the surface of the ground that when tested, has physical characteristics (such as turbidity, temperature, conductivity, or pH) that closely correlate with surface water chemistry; and/or well water that rises in temperature soon after precipitation events; and/or ground water that is found to contain microorganisms or debris that are typically found only in surface water such as algae, organic debris, large-diameter pathogens, or insects.
