As the demand for geoelectric integrity surveys performed as the final stage of liner construction quality assurance (CQA) increases, the number of surveyors certified by the TRI-CORP Liner Integrity Center (T-CLIC) also increases.
To date about 200 people have taken the 1-day classroom and 1-day, hands-on instructional course at the TRI campus or at other locations.
Special sessions have been held by request of government agencies and private companies in Houston, Texas; Albany, New York; Halifax, Nova Scotia; Edmonton, Alberta; and Manila, the Philippines.
At the TRI campus in Austin, hands-on instruction is provided in three test cells simulating three common liner survey conditions: water-covered, soil-covered, and exposed. The exposed liner has three different substrates: conductive geomembrane, conductive geotextile, and geosynthetic clay liner (GCL). We would like acknowledge GSE and Sensor for their generous supply of materials here.
GAINING CERTIFICATION
Certification from T-CLIC involves more than attendance at the two-days of class and test cell training. T-CLIC performs audits and exams later on to ensure retention of skills. The course presenter and field auditor is Ian D. Peggs, I-CORP International, Ocean Ridge, Florida.
Of those who have taken the liner integrity survey course, 39 have proceeded to a one- or two-day field audit during their first or a subsequent production survey followed by a 90-minute closed book written test of 40 questions based on actual surveys. Questions are both multiple choice (with maybe more than one correct answer) and drawing/essay type. Marks are given for each correct answer and are deducted for each wrong answer.
Of these 39, 24 have achieved T-CLIC certification.
