Vedclass · Answer

(A) The project at Arcata,California,involved the creation of an integrated wastewater treatment process.
Scientists from Humboldt State University created a series of six connected marshes over $60$ hectares of marshland.
These marshes were seeded with appropriate plants,algae,fungi,and bacteria,which neutralize,absorb,and assimilate the pollutants,including heavy metals.
Therefore,the correct answer is $60$ hectares.

In the treatment of wastewater,scientists at the Arcata Marsh (a project associated with Humboldt State University) developed a series of six connected marshes over how much area to remove heavy metals and other pollutants?
