Abstract
The invention relates to a method for microbial remediation of underground water petroleum hydrocarbon contamination by regulating soil buffer capability, which comprises detecting the soil particle size of contaminated site soil, dividing the contaminated site soil into coarse-grained soil and fine-grained soil; dividing the contaminated site soil into high buffer capacity soil and low buffer capacity soil; and adjusting the composition and ratio of a biostimulant solution added to the contaminated site soil based on the classification of the contaminated site soil. The detecting step includes classifying soil with a particle size between 0.075 mm and 60 mm and a mass greater than or equal to 50% of the total mass as coarse-grained soil; and classifying soil with a particle size not greater than 0.075 mm and a mass greater than or equal to 50% as fine-grained soil.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
