A method and apparatus for determining the effectiveness of water treatments in situ (especially in pulp and paper processes) by measuring the amount of deposition of organic and inorganic contaminants, (e.g. biofilm) on a stainless steel coupon suspended in the water. The coupon is attached to a weight sensor within a reservoir tank that includes a fluid inlet and outlet to let water flow over the surface of the coupon to allow contaminants present in the fluid sample to deposit on the coupon surface. At regular intervals, the reservoir tank is drained and the coupon is allowed to dry and is weighed. A computer system attached to the weight sensor can analyse a series of weights and an automated method of adding biocidal agents to the water can be activated if the contaminant level is too high.
