Ignoring the question of leaching, it's obvious that the statement "it will taint the water enough to make the taste unbearable" can hardly be true.Concrete has been used for cisterns, dams, wells, and pipes for centuries, and surely that direct continuous contact would produce far more contamination that what could possibly filter through a plastic container.

A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater ( sewage) flows for basic sewage treatment. [2] Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). [2]

Tank leaching is usually differentiated from vat leaching on the following factors: In tank leaching the material is ground sufficiently fine to form a slurry or pulp, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, this reduces the cost of size reduction;

The CIL circuit consists of two trains of eight tanks in series fed from a common leach tank. The loaded carbon passes into a 15 tonne acid wash column. The gold is recovered from the loaded carbon in two 15 tonne elution circuits. Gold is recovered from solution by electro-winning and smelted in the CIL smelt house in an induction furnace.

A typical septic drain field (see Figure 1), also known as a leach field, is a series of perforated pipes that are set in trenches and buried with aggregates (½- to 2½-inch gravel or ½- to 4-inch rubber chips) and soil. These drain lines are at a minimum depth of 6 inches and are typically 18 to 36 inches wide.

We send this slurry to leaching tanks, where we add a weak cyanide solution to the slurry, which leaches gold and silver into the solution. This process removes up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution. The gold attaches to the carbon and is pulled from the solution.

Currently, cyanide leaching is the chief method use. In this technique, sodium or potassium cyanide solution is either applied directly to ore on open heaps or is mixed with a fine ore slurry in tanks. Heap leaching is generally used to recover gold from low-grade ore, while tank leaching is used for higher grade ore.
