The U.S. Federal Water Pollution Control Act P.L. 92-500, specifies legally acceptable methods for testing wastewater. The analysis of cyanide is performed according to the methods set out in the "Standard Methods for the Examination of Water Wastewater". This method indicates that it should be added prior to wastewater mercury chloride I (HgCl), to decompose the complex cyanides and thus be able to take a sample to perform the content analysis of cyanide. However, it should also be noted that the Illinois Pollution Control Board (IPCB) has established wastewater quality standards that limit the content of mercury (such as Hg) at 0.0005 ppm maximum in any effluent. A company that has a wastewater treatment plant applies 200 mg of mercury chloride per day before each cyanide analysis. a) Will this company comply with the maximum allowable limit of mercury according to the IPCB if discharges 100,000 gal/day of effluent and performs a daily cyanide analysis?
