− | <br> | + | <br>The manufacture of stainless steel and sewage sludge are sources of chromium contamination in soils. It is an environmental concern because excessive concentrations are toxic to living organisms. A significant reading of chromium was detected on 15 August 2003 at Kohsoom, the station closest to the site of waste dumping. |

On 15 August 2003, significantly high levels of nickel were detected across several stations: Kannika (the highest reading), Chai, Kohsoom, Somchair and Sakda. In 2011, 2012 and 2014, Kohsoom also saw high Nickel readings detected. |
