In this article we will explain Landfill Quality Assurance (QA) and the importance of ensuring that the universal principles of QA, are applied to landfill construction and development. We will elaborate on why QA is so important for a landfill, especially a landfill liner later in this article. But, meanwhile we would ask our readers […]
The purpose of Landfill Construction Quality Assurance is to ensure that the landfill is constructed in full compliance with the specification. The primary responsibility for ensuring this, rests with the landfill construction (civil engineering) contractor. The landfill CQA Engineer who is resident on the site, provides independent inspection and verification of the work, and receives […]
The rate of flow (flux – Q) per unit area of liquid through a liner is a function of the hydraulic conductivity (k) and the hydraulic head (i), and can be approximated by applying the following equation, attributed to Darcy: Q=ki (1) In the case of vertical flow under gravity, the hydraulic head (i) is […]
We explain why the landfill CQA engineers involved in CQC and CQA hold a such a vital role as the final link in ensuring that the landfill design is constructed to the specified requirements. CQ Engineers never forget! Future generations depend on you!
Landfill CQA Actions up to the Start of Construction Once the landfill design engineer has completed the landfill design and the specification has been substantially completed, it is possible to write the landfill Construction Quality Assurance (CQA) Plan, which the construction contractor will then be required to follow, and which will once completed be reported […]
