Purple Bamboo Park, east of a Great Lakes waters, the lake was drained to do reduced infiltration project. Conservationists argue that the project will affect the aquatic environment and groundwater recharge. Without an environmental impact evaluation of the environmental protection department, was also suspected violation.
site east of the Great Lakes water to be drained
10 am today, Purple Bamboo Park, east of the Great Lakes, has set up several hundred meters long, one high Weidang. Through the gap there are workers to see work, but I do not know doing what works.
reporter standing on the east coast to see a stone bridge, east of a Great Lakes waters, the lake has been drained, exposing the bottom of the lake is full of mud. Can see patches of weeds, there are outcrops of the lotus from the mud.
from the lake about 200 meters east to west, a north-south lake spans both sides of the cofferdam, to block the west side of the lake. Cofferdam, the excavator is operating, will be a color similar to the silt and clay lake bottom, laying in the bottom of the lake.
asked workers at the site that it is the park’s lake being reduced infiltration project. Started in October of this year, is expected to end in January next year. Reduced infiltration aim of the project is to reduce water leakage in order to save limited water resources.
questioned the lake drained impact benthos
lake reduced infiltration works at the same time, by some environmentalists questioned.
environmental organizations Dahl asked social researcher Shao Wenjie natural knowledge that the lake drained and then cover, bottom organisms may be destroyed. Projects using clay, the impact on the aquatic environment is not known.
In addition, some people worry that reduced infiltration project will make the lake is not easy to penetrate down to the groundwater recharge is difficult to obtain, which is Beijing’s groundwater resources increasingly strained described as “worse.”
● zoo respond
project using natural clay, not the production of chemical raw materials impermeable membrane. And components and mud near the lake, “the equivalent of more than a layer of mud at the bottom of the lake”, does not impact on the water.
projects using clay and impermeable membrane is different than a reduction of water leakage, recharge groundwater, rather than completely block the channel, has little effect on groundwater.
alleged breach of the EIA without making
reduced infiltration project started, whether done by the environmental protection department of environmental impact assessment?
Shao Wenjie said that any possible impact on the environment of the project, the EIA should do first, confirm compliance with environmental standards before being started.
Purple Bamboo Park, if not to do the EIA, the project starts alleged violation.
● zoo response
park officials said, reduced infiltration before the start of the project, after approval of higher authorities agreed and funding.
also invited to the water sector, water experts will convene a review “them from the professional point of view, endorsed the use of clay as a way to reduce the diffusion layer.” Garden party, but admitted, did not do in the environmental protection department EIA .
