Dug & Drilled Well Colour Video Inspection

Downhole Dug and Drilled Well Video Camera

Atlantic Water Investigations Limited owns and operates a well video inspection color camera with led lights located at the camera head that is capable of submerged depths of 1000 feet, attached to a 1000 foot kevlar reinforced cable, so that a down-hole video surveys can be conducted. The video is recorded to DVD with optional VHS recording. There is onscreen depth displayed in either metres or feet. A mirror can be attached to provide side profiling if required.

This provides clear images above the water, pinpointing actual down-hole conditions that can contribute to water quality limitations of drilled wells, such as:

  • biofouling material buildup inside of casing
  • leak around pitless adaptor
  • leak around welded casing joints
  • water seepage around casing/drive shoe
  • water flowing through shallow fractures above the water table located below the drive shoe, etc.

Conditions a video inspection reveals that can contribute to the water quality limitations of dug wells are:

  • biofouling material buildup inside of well
  • shifted crocks with water seepage between crock joints, water intake line
  • frost heaving shifted crocks
  • falling rocks, caving of rocklined wells
  • sources of bacteria contamination such as tree roots, dead rodents, insects (spiders, ants, earwigs, worms), etc.

Based on the video inspection, methods to try and eliminate the problem through appropriate corrective action can be recommended. A well video inspection was performed on this well using a color camera with led lights located at the camera head. Based on the video inspection, methods to try and eliminate the problem through appropriate corrective action can be recommended. There is onscreen depth displayed in either metres or feet.

Atlantic Water Investigations Limited assumes that the video inspection can be performed with the pump in the well. In some cases where there is the potential for the pump wiring to interfere with the placement of the camera, and tangling of the camera upon retrieval, the pump will need to be removed for an additional fee.
