FAST-TEK owns and operates mapping-grade Global Positioning System (GPS) survey equipment. California state groundwater reporting laws require GPS information and laboratory data for all monitoring sites. GPS is a satellite navigation tool that captures coordinate data after a differential correction. Soil or groundwater sampling, soil remediation, and even cartographic mapping, site restoration and erosion control projects are performed using GPS with sub-meter accuracy. FAST-TEK downloads the field data into Arc-View Global Information Software (GIS).
