Significant destruction has occurred in New Zealand as a result of a 7.8 magnitude earthquake near the town of Kaikoura, about 2 hours drive north of Christchurch. Video footage shows significant surface rupture causing damage to homes and infrastructure. There have been numerous landslides as well. The town of Kaikoura had to be evacuated, including about 1,000 tourists, after it was left without power by the event. Only two casualties have been reported based on the information I have heard, and it's fortunate there was not more loss of life. [Source: CNN.com. Image: Mirror.co.uk]

Eurofins Case Study: ESdat Online and ESdat Lab Portal
The Eurofins Field Services Groundwater team conducts compliance monitoring on behalf of various Victorian Landfill operators.
New analytical results from the Eurofins lab and secondary labs were combined into spreadsheets containing ongoing and historical data on behalf of the landfill operators. This was a time consuming, labour intensive process. Uncontrolled, 'hand-me-down' spreadsheets can also introduce or hide critical errors.
Eurofins has adopted ESdat Online and the ESdat Lab Portal to replace the historic spreadsheets in order to increase efficiency and accuracy, and provide the landfill operators with direct access to their consolidated historical results through a web interface.
