During which weather are soils with high T-times particularly difficult to handle?

• A. Dry weather
• B. Cold weather
• C. Wet weather
• D. Snowy weather

Answer: (C)

Soils with high T-times move water slowly through the profile. When the weather is wet, the pore spaces are already filled with water, so there’s little room left to accept more effluent. That combination—slow movement plus high moisture—means the absorption area can’t drain effectively, leading to surface ponding, poor treatment, and more trouble for handling and design. In dry weather, air-filled pores can help infiltration, and cold or snowy conditions mostly reduce infiltration due to freezing, but they don’t compound the challenge the way saturated, wet conditions do for soils with high T-times.
