Publication Summary

Evaluation of environmental impacts at solid waste facilities is dependent on obtaining air, soil and water quality samples that are representative of the environment. Obtaining representative ground water samples requires careful attention to monitoring well design and construction and sampling procedures. This document provides an understanding of the ground water monitoring requirements (WAC 173-304-490) as stated in the Minimum Functional Standards for Solid Waste Handling (MFS). The document is intended to be utilized by state inspectors, hydrogeologists and engineers and by local health departments, public works departments and their consultants in reviewing ground water monitoring systems, proposals, and monitoring results. It is also intended to be a reference manual for other hydrogeologists and engineers who are not cognizant of or familiar with the requirements for ground water monitoring at solid waste landfills in the State of Washington.
