The leachate riser or wells arc first opened and allowed to equilibrate with the atrtosphere. 2. The in;tchata elevation is tben measured from a set location using a conducrivity-based water-level meter. The level is generally measured from a WrVeyud mark on the north run of the casing. 3. A leachate samplo is tLen collected using a clean,disposable Wilcr. 4. The sample is libeled and immediately stored in an iced cooler pending transport to the analytical laboratory.
