By means of automatic control units (Dataloggers), placed inside piezometers, we can monitor continuously, and also remotely, the values of the water table elevation, Electrical Conductivity (EC) and Temperature (T). By means of multiparameter stations we can monitor Temperature (T), pH, Redox Potential (ORP), Dissolved Oxygen (DO) and Electrical Conductivity (EC) values of groundwater, while for soils and sediments we can acquire Temperature (T), pH, Redox Potential (ORP) values. Verification of the presence of supernatant in groundwater (LNAPL) by water-oil interface. Geosyntech performs acoustic impact assessment activities and phonometric surveys both ante operam, and post operam pursuant to current regulations. In addition, we perform both indoor and outdoor environmental air monitoring activities by means of static air samplers, Flux Chamber, Canister and Geoprobe of interstitial gases (Soil-Gas Survey). Verification of air quality by sampling with vials and membranes, laboratory analysis referred to the limits of the current regulations. Geosyntech performs marine water quality sampling and monitoring activities using Niskin Bottle, Secchi Disk, Densimeters, Turbidimeters, etc. We carry out vibrometric, dust emission control and airborne substance testing and analysis.
