Title
(EN) DEPTH DISCRETE MULTI-LEVEL DOWNHOLE SYSTEM FOR GROUNDWATER TESTING AND MANAGEMENT
(FR) SYSTÈME DE FOND DE TROU À PLUSIEURS NIVEAUX DE PROFONDEUR DISTINCTS PERMETTANT DE TESTER ET DE GÉRER DES EAUX SOUTERRAINES
Abstract
(EN) The invention provides a depth discrete multi-level downhole system for discrete multi-level groundwater testing and management which is easily manufactured from inexpensive materials for incremental installation, long term viability and reusable removable. The system includes a casing assembly including blank casings, sampling casings and packer casings telescopically joined to provide an interior sampling line cavity for a plurality of sampling lines each extending from an internally applied port through the casing wall and thence to the ground surface, or, alternatively sampling units for groundwater data gathering.
(FR) L'invention concerne un système de fond de trou à plusieurs niveaux de profondeur distincts permettant de tester et de gérer plusieurs niveaux distincts d'eaux souterraines qui est facilement fabriqué à partir de matériaux peu coûteux pour une installation incrémentielle, une viabilité à long terme et amovibles et réutilisables. Le système comprend un ensemble boîtier comprenant des boîtiers vides, des boîtiers d'échantillonnage et des boîtiers de conditionneur reliés de manière télescopique pour fournir une cavité de ligne d'échantillonnage intérieure pour une pluralité de lignes d'échantillonnage, chacune s'étendant à partir d'un orifice appliqué de façon interne à travers la paroi de boîtier et vers la surface du sol, ou, en variante, des unités d'échantillonnage pour collecter des données d'eaux souterraines.
