Investigation for Soil contamination

   

   

------ Remember “LOVE CANAL” ‘s case----------

When you are going to purchase some land, it is better to investigate the history of the land you are going to purchase. And if there was factory or so, it may be contaminated by hazardous substances(see the table below).

IF you feel anxiety for soil contamination, feel free to contact us. We will make a plan of investigation for soil contamination.
