lagoons to flood and spill into the environment. Which of the following might be an effect of a leaking waste lagoon?

1.Runoff from a leaking lagoon could lead to soil erosion downstream.

2.Drinking water in groundwater aquifers could be contaminated.

3.The properties of soil downstream could be altered, affecting ecosystems.

4.Carbon dioxide emissions could increase and affect the global climate.
