If sewage is smelled on a leaching bed, which observation points to a breakout?

• A. Soft, spongy ground
• B. Sloped surface
• C. Uniform moisture
• D. Glossy surface

Answer: (A)

When a septic leaching bed breaks out, wastewater pushes toward and onto the surface, signaling a failure in the absorption area. Soft, spongy ground around the bed is the clearest sign because the soil has become saturated and loses its firmness where the effluent is seeping through. That cushiony, damp feel points to wastewater breaking through to the surface. The other observations don’t fit as well. A sloped surface would tend to shed water rather than allow it to pool and surface. Uniform moisture suggests general wetness from groundwater or recent rainfall, not a localized breakout. A glossy surface could indicate a film or different substance on the soil, not the typical breakout of sewage.
