This literature review investigates the effectiveness and applicability of free and dissolved gas sampling techniques for establishing baseline conditions in water wells. The author, Trevor Hirsche, synthesizes existing research to evaluate the methodologies, challenges, and benefits associated with these sampling approaches in hydrogeological and environmental assessments. The review aims to provide a foundational understanding for practitioners and researchers involved in water resource monitoring and management.

This work is presented as a comprehensive literature review, indicating a focus on synthesizing existing knowledge rather than presenting novel research. Its value likely lies in its thorough examination of sampling techniques for water wells, providing a foundational resource for environmental scientists and hydrogeologists. The review's utility is expected to be in guiding practitioners toward effective baseline testing strategies.
