Hello, I have a dataset with 1400 rows and 12 columns, I have found the outliers, I have the row numbers currently, I am unable to find a way to delete those rows from the dataset. I am confused about using a function to delete the rows or are there any inbuilt functions?

Let data be my dataset, and pH is my column, so I am checking here if my pH is less than 2.8 then the position of those values are returned

Newdata[Select[#pH < 2.8 &]] // (Position[Newdata, Alternatives @@ #] &) // Flatten

The returned value is {136}. How do I delete this particular row from my dataset. Thanks in advance.
