The 3-Channel CMT® Multilevel Monitoring System is ideal for direct push installations, as it is only 1.1″ (28 mm) in diameter. Often with these installations, the annulus available is too small to accurately place sand and bentonite layers for isolating the monitoring zones. Therefore, bentonite cartridges (spring and pre-formed) have been developed to give reliable seals between… Continue Reading »

The CMT System (Since 1999) CMT offers in-field design flexibility, low cost and is easy to install. The number of monitoring ports, port locations, install depths, and monitoring strategy, can all be accommodated and designed right in the field. The single tube offers effective sealing.The 7-Channel is 1.7″ (43 mm) and the 3-Channel is 1.1″… Continue Reading »
Stainless Steel Bladder Pumps can lift from depths of 500 ft (150 m) below grade, and PVC models from 100 ft (30 m). Samples can be obtained from greater depths using a drop tube assembly. This places the screened filter intake of the pump as deep as necessary to access the sample zone required. Easily installed without tools on existing pumps,… Continue Reading »
Solinst Bladder Pumps have been long known to have Teflon® bladders backed with a 10-year warranty. These are ideal for dedication and VOC monitoring. Solinst also offers an inexpensive disposable polyethylene bladder, for clients who use a portable pump, or prefer to replace bladders at regular intervals, to prevent cross-contamination. Replacement is fast and easy, with no… Continue Reading »
Can you tell the difference? Which is Right for You? Both have their advantages. Bladder Pumps have low flow capability and ensure that no drive gas comes into contact with sample water, making them ideal, and approved by regulators worldwide for VOC sampling. Select a Bladder Pump for higher regulator acceptance and lower flow rates. Double Valve Pumps provide greater… Continue Reading »
White Young Green Environmental Limited (WYG) is an experienced environmental consulting firm operating in the United Kingdom. WYG was given the task of developing a cost effective means to isolate and reliably sample groundwater quality, and obtain hydraulic head data from various zones, in a complex geological setting, to give detailed vertical gradients. The investigation… Continue Reading »
Contaminants were identified in the subsurface at Rhine Main Air Base, Germany, in a sand and gravel aquifer. The contamination was complex due to two separate sources: a fire training pit, and a former gas station that had leaked various compounds, including BTEX, TPH, PAH, and TCE. The aquifer extends from 7 m up to… Continue Reading »
