A sinkhole that opened up in January was surrounded by orange plastic fencing outside a suburban home at Lisa Drive in West Whiteland Township, Chester County.

Over two years of construction, the Mariner East 2 pipeline — which carries natural gas liquids across Pennsylvania to an export terminal in Delaware County — has been plagued with delays and mishaps.

The construction has destroyed some private water wells, opened sinkholes, and sparked a criminal investigation by the Chester County District Attorney.

On the latest episode of The Why, a podcast from WHYY, StateImpact Pennsylvania reporter Susan Phillips takes us along the pipeline’s winding path and explains why the DA is taking this unprecedented step.
