Our field monitoring services can be divided into
three main areas:
- Water Monitoring
- Occupational hygiene monitoring
Our team of trained field technicians performs sampling procedures in a variety of field conditions and geographical locations. They are supported by our fleet of all-terrain vehicles that conforms to client safety requirements.
How do we ensure continuity and credibility?
We make use of electronic hand-held devices that provide task lists to field technicians and records the date and time as well as the location of sampling actions performed. This information is synchronised via satellite with the Aquatico SQL Server database.
What sets us apart in the field?
PDA Units: All field monitoring is conducted with the use of PDA units. With each monitoring locality a set of predefined observations –customized by the project manager i.e. flow, water level, smell etc – is answered. The software will not allow the technician to continue to a next step without entering the required information.
Photographs: Prior to taking any sample, the software will also require that a photo be taken, this will be automatically named and filed, with a time and GPS coordinates as reference to the sample, providing an audit trail for sampling.
GPS pinpointing: The GPS coordinate taken within this step will be verified against the predefined coordinate for this locality. As soon as the technician is not within a 30m radius (customizable parameter) of the predefined position for the specific monitoring locality, the software will immediately prompt a warning on the screen that it is not the correct locality.
Pre-bar-coded containers: All sample containers are pre-bar coded and the technician must scan the sampling container prior to taking the sample, This will firstly ensure that it’s the right locality and secondly that the correct sampling container type is used (i.e., organic samples in glass bottle, microbiological samples must be in sterile containers etc).
Step-by-Step execution: Only at the point where all the requested tasks are completed will the software acknowledge that the function is completed and prompt the technician to proceed to the following locality.
SQL Database: Once the field technician arrives back at the laboratory, all the samples are delivered to sample reception and the handheld unit is connected to the mainframe system via docking stations as presented in the images below. All sampling info is downloaded into an SQL database.
Luna cooling units: All samples taken in the field are stored in National Luna cooling units to ensure proper sample transport to the laboratory (at 4°C).
