前期遗留个别黑土存在有机质超标风险；Hazens在原有有机质检测基础上

Some black soils left over in the early stage have the risk of organic matter exceeding the standard; on the basis of the original organic matter testing, Hazens separately arranged three sets of organic matter sampling. The three sets of organic content were 0.67, 0.71, and 0.98, which met the requirements of the filling design and specifications.
