Hot spring waters and groundwaters

Water samples can also be collected using evacuated flasks or Giggenbach bottles 

Groundwater pumped from wells is normally sampled using copper tubes that are connected to the well by Tygon tubing. Caution must be exercised to sufficiently flush the sample device prior to crimping the copper tube. A Y connection may be used to release excess water pressure during and after pinching of the copper tube.
