- C. G. Galgowski and
- W. R. Wright2
An inexpensive variable-depth ground-water sampler for 4-cm i.d. PVC well casing is made from readily available materials. The sampler will extract water samples at any selected depth from a shallow aquifer via a perforated well casing without mixing water from different strata. Water samples can be obtained from a depth of about 10 m with standard vacuum equipment.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
