Features
Groundwater monitoring well casings and screens will produce fouling, blocking or corrosion. If the situation continues to deteriorate, it may lead to loss of function. Therefore, in order to extend the life of the well to ensure that its function is normal, regular inspection and maintenance of wells is necessary. Well photography works as similar as the principle of endoscopy in general, the camera lens directly into the bottom of the hole, to see the situation in the well directly through the monitor screen.
