Physical and Chemical Parameters (PC)
This testing panel includes multiple parameters for physical and chemical analysis of water by Robotic Analyzer and CFA technology. A total of 15 parameters are analyzed under this criteria, other than taste and odour.
Essential parameters to be analyzed in Physical and Chemical analysis of water
The physical characteristics of water are very important as they are the first visibly noticeable factors. Ideally water should be colourless and odourless with a neutral pH. Presence of dissolved components like clay, silt, algal materials, etc. makes water turbid and a pH change can make it corrosive.
Ideally pure water should be non-reactive; however presence of some chemicals can alter this property and adversely affect health. Though tap water supplied is chlorinated, excessive chlorine generates chloroform which is carcinogenic. Also nitrates can impair oxygen transport in the body causing brain death, while fluoride can cause dental fluorosis and affect skeletal tissues. Sulfide causes diarrhea, while anionic detergents if ingested, change the pH of blood and can also burn the tissues. Presence of cyanide is generally due to contamination by industrial effluents and though the hazardous effects of excess deposition manifests quite late, it may affect thyroid and cause nerve damage.
