Which of the following could indicate that a property was previously used as a waste disposal site?

The presence of soft spots, mounds, and discolored soil can indeed indicate that a property was previously used as a waste disposal site. These physical characteristics are often a result of disturbed land and can signal underlying issues such as buried waste. Soft spots may suggest areas where the ground has settled due to waste decomposition, while mounds can signify where land has been filled or buried with waste materials. Discolored soil can be a sign of contamination, potentially from chemicals or decomposing organic matter associated with waste disposal activities.

Identifying these signs during an inspection can be crucial for assessing environmental risks and determining the necessary remediation measures before a property is developed or repurposed. Understanding these indicators helps professionals ensure compliance with environmental regulations and protect public health.
