The purge process (~2 gallons) further removes any potentially affected water and the sample is usually drawn from more than 10 ft from the liner in fractured rock. The sampling system, since 2002, is entirely of PVDF tubing which is far less absorptive than the typical LDPE tubing used for sampling. In the special case of a very large vertical gradient, the tubing in the sleeves may be nylon which is well purged by the sampling procedure.

The installation involves pulling the liner off a shipping reel, creating an annular pocket that is lowered inside the casing.  Water is added to this pocket to generate pressure for the eversion process, allowing the liner to displace borehole water and seal to the borehole wall.  <\/span><\/p>\n<p class=\"font_8 wixui-rich-text__text\"><span class=\"wixui-rich-text__text\">The Water Flute multilevel groundwater system can be installed in open bedrock wells and multi-screened cased holes in overburden using the eversion process. Installation depends on factors like hole depth, diameter, and water table level. If the borehole is too tight, water can be pumped from beneath the liner using a pre-installed pump tube, which is removed after installation to create a seal.  <\/span><\/p>\n<p class=\"font_8 wixui-rich-text__text\"><span class=\"wixui-rich-text__text\">Once installed, formation water flows into the screen and up the tubing inside the liner, allowing measurement of water levels from the surface. Gas pressure is applied to purge and sample the Water Flute, with large volumes collected (generally 4.5 litres per stroke) without aeration, making it ideal for VOC sampling. The Water Flute ensures high-quality discrete groundwater samples directly from the formation.  <\/span><span class=\"wixui-rich-text__text\"><\/span><\/p>\n<p>[\/et_pb_text][et_pb_button button_url=&#8221;@ET-DC@eyJkeW5hbWljIjp0cnVlLCJjb250ZW50IjoicG9zdF9saW5rX3VybF9wYWdlIiwic2V0dGluZ3MiOnsicG9zdF9pZCI6IjU1ODIifX0=@&#8221;
