The Impact of Site Conditions on the Electrical Surveying of Pond Liner Installations
Contractors, with over six year's experience, were engaged to survey and report on the condition of a HDPE liner in Queensland, Australia. The 35,000 m2 pond was a clay lined, cut and fill construction with a trench anchored, 2.0mm HDPE liner with no appurtenances or perforations. All fill and discharge was undertaken over the top of the basin. The pond contained a solution of 7000ppm saline water, a by-product of coal seam gas extraction. In the course of preparing the survey equipment (in accordance with ASTM.D7002 , ASTM D.7007 and ASTM D7703), it became evident that the voltage was unstable and the contractors were unable to electrically identify the calibration puck, thus making it impossible to identify the parameters for the equipment settings, or to successfully carry out the requirements of the test regime. Further extensive investigation eventually identified a set of conditions peculiar to the site, and which impacted on the surveyors' ability to undertake effective testing. This paper intends to explore this specific incident, in which several major site related factors, including: (1) Salinity levels of contained liquid; (2) Substrate conditions; (3) Metallic properties of contained pond sediment, and (4) Ambient meteorological conditions The above contributed directly to the detrimental effect on the electrical surveying of a pond liner. The subsequent importance of understanding site conditions and nuances when undertaking electrical survey is highlighted within.
