An apparatus for detecting oil and other lighter-than-water contaminants in an effluent stream in a sewage system. The apparatus includes a disposable detector which floats in the effluent stream and detects oil and other contaminants having a specific gravity lighter than the water by absorbing the oil and such contaminants in an oleophilic material, permitting the oil and other contaminants to rise and collect in a collection tube. The acidity or pH of the effluent being monitored is determined by routing a portion of the effluent stream across a litmus paper. |
