Colorful Hebei pits heavily polluted

Tests show that colorful sewage pits found on farmland in Langfang, Hebei province, are severely polluted and must be treated quickly, according to an investigative report released on Wednesday.

A cluster of red and yellow pits occupy a strip of arable land in Dacheng county, of which the largest covers more than 170,000 square meters, equal to 23 standard soccer fields.

Surrounding the pits is black sludge, and piles of dark-red waste residue were discovered at a nearby industrial zone, according to aerial photographs provided by Chongqing Liangjiang Voluntary Service Center, an NGO, which went viral online on Wednesday.
