Groundwater Testing

Groundwater is the primary source of drinking water for approximately ½ of the world’s population. Immense amounts of groundwater are utilized for agriculture. Even though the groundwater is largely protected from contamination by intact soil and rock layers, it is still threatened by pollution caused by industrial and agricultural activities, since this natural protective function of the groundwater cover is not always sufficient.

STEMart provides comprehensive groundwater testing service to determine if there is evidence of negative environmental impact.
