Water experts yesterday called for a stop to an ongoing project to cover a riverbed with an impermeable plastic cover to create a man-made lake in Jinan to be scrapped.
Experts worry the plastic will disrupt the natural process of river water seeping into the ground, which they said would threaten the groundwater supply in the city, the capital of East China’s Shandong Province.
The project, conducted by the Western Town Headquarters under the municipal government, got under way in January despite much controversy.
It aims to turn a 2.3-kilometre section of the Beisha River into a man-made lake, adding a “scenic spot” to the newly-built university town.
