Using automatic control units (Dataloggers), positioned inside piezometers, we can monitor continuously, and even remotely, the values ​​of the water table, the Electrical Conductivity (EC) and the Temperature (T). Using multi-parameter control units we can monitor the values ​​of Temperature (T), pH, Redox Potential (ORP), Dissolved Oxygen (DO) and Electrical Conductivity (EC) of groundwater, while for soils and sediments we can acquire the Temperature values (T), pH, Redox Potential (ORP). Verification of the presence of supernatant in the stratum (LNAPL) by means of a water-oil interface. Geosyntech carries out acoustic impact assessment activities and phonometric measurements both before construction and after construction work in accordance with current legislation. In addition, we carry out environmental monitoring of both indoor and outdoor air using 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 referring to the limits of current legislation. Geosyntech carries out monitoring activities of the quality of marine waters. We perform vibrometric checks and analyzes, to control the emissions of dust and airborne substances.
