groundwater table Applications

Monitoring VOCs in porewater in the unsaturated zone is now possible.

Sorbisense regularly offers new options for using the patented Sorbicell, which is used to monitor surface water, wastewater and groundwater.

The latest is almost as “ground-breaking” as the SorbiCell itself. Until now it has been difficult, if not impossible, to directly monitor for volatile substances in pore water in the unsaturated zone. But the environmental consultancy firm Ejlskov A/S in Aarhus combined the use of Sorbisense sampling equipment with the proven technology of soil water samplers. With this combination, a practical new method is made available, which allows for monitoring the presence of porewater-dissolved VOCs above the groundwater table. This provides a significantly improved basis to define and determine the leaching risk to the groundwater, and thus allows for better and more cost-efficient decisions to prevent the pollution in reaching the groundwater.

A simple construction with multiple options

The application uses SorbiCell VOC combined with suction cells, soil water samplers. When installed correctly, and applied with the correct procedures, the suctions cells extract capillary bound water from the soil matrix. The system demands no other resource than a container that is put under vacuum. The vacuum in the container then ensures a flow through of the Sorbicell over a period of time, fx. 2-3 weeks. The method is highly suitable for monitoring a site over longer periods of time.

Scalewatcher North America, manufacturer of the original, patented and award-winning computerized electronic water-conditioner, states in its literature that the device is produced to last at least 20 years and comes with a 10 year warranty. However, no reports have been received on the longevity of the units sold since the company was launched over 20 years ago. Now a customer in Gilroy, California has come forward requesting a new Scalewatcher unit after the device she purchased in 1992 finally stopped working. She purchased the new Scalewatcher from local dealer, Aqua Genesis, and reported that: “ I noticed that the sprinklers are covering more of an area than before. When I squirt water on the black and white tile patio table there are no longer any calcium spots even if I do not dry it off. The tile shower and the clear shower door are easier to wipe down after my shower. The new ScaleWatcher is much better than before. It certainly was time to replace the old one.” The new, innovative, electronic Scalewatcher water conditioner uses proven technology to quickly and effectively dissolve existing limescale and prevent it recurring, returning water systems and water-fed appliances such as kettles, washing machines and dishwashers to their former efficiency. It also removes scale around faucets, sinks, baths, plugholes and shower roses as well as preventing white marks on shower screens and mould on shower curtains. The system requires no plumbing, chemicals or maintenance and is environmentally friendly. In addition scale costs money for householders through additional cleaning products, the early renewal of water–fed equipment and additional costs to heat water. It is estimated that 40% more energy is needed to heat water in a system fouled with ¼ inch of limescale. Commenting Jan de Baat Doelman, President of Scalewatcher North America says: “We have always built Scalewatcher electronic water conditions to last and this latest information confirms the device’s longevity. Scalewatcher will pay for itself in less than three years and then carry on providing homes with a scale free environment many more years to come. ” Scalewatcher models are based on continuous research and over 20 years experience and expertise as market leaders in electronic scale control with countless units sold worldwide. The patented Scalewatcher systems start at $248.00 USD and are capable of treating pipe sizes from one to 120 inches. All Scalewatcher systems come with a full performance guarantee and include free shipping throughout North America.
