No one likes to talk or think about septic systems, which is exactly why they are such a problem. Septic systems are designed for a specific capacity and to be periodically maintained. Consequently, the leach field may become stressed and contaminants such as bacteria, nitrates, metals, and a variety of nutrients maybe released, escaping the natural purification action which the field was designed to provide. In addition, contaminants such as detergents, cleaning agents, and solvents sent down the drain typically end up in groundwater. Natural house-hold and manufactured alternatives are available for many of these products, several of which are listed below.
