A fluid sampling apparatus is disclosed for withdrawing samples of groundwater or other fluids from a well or other monitoring site.

The apparatus preferably also includes a removable and portable controller means adapted for easy and convenient transportation and connection to such dedicated fluid sampling components at various wells or monitoring sites. A recovery, collection and control system for cleanup of leachate or other liquid material or contaminated groundwater from a landsite is also disclosed. Such system preferably includes fluid-operated pump means, each with associated preferably pneumatic controller apparatus, as well as a collection system for collecting, monitoring and controlling the collection and disposal of hazardous or other material withdrawn from in-ground wells at the landsite.
