Subject Black Particulates Found On Surface Of Copper Pipe

LA Testing was asked to identify the origin of a material consistently building up around the copper pipes located in a basement area.  LA Testing conducted analysis identified the unknown particulates as Copper Sulfide.  This chemical compound is a commonly found byproduct of corrosion of copper surfaces exposed to hydrogen sulphide. Based on the findings client was able to link the contamination to the direct exposure of the copper surface to the damage sewage pipe.
