Compost Composit Sample Log
NCSU Waste Reduction and Recycling Compost Facility and Research Coopreative
In accordance with Rule .1408 (a), a composite sample of the compost produced will be analyzed every six months or every 20,000 tons. The sample tested for pathogens will be collected
as a composite sample from finished compost onsite on the same day it is taken to the lab for analysis. The sample that is collected for metals analysis is to be collected and composited
over a six-month period from each batch of compost. At least three individual samples (of equal volume) will be taken from each batch produced in separate areas along the side of the
batch. Each sampling point will be at a depth of two to six feet into the pile from the outside surface of the pile. Manmade inert tests are performed by in-house personnel. They will
be determined by passing a dried, weighted sample of compost product through a one-quarter inch screen. EPA Method 160.3 shall be used to dry the sample. The material remaining on the
screen shall be visually inspected, and the foreign mater that can be clearly identified shall be separated and weighed. The weight of the separated foreign matter divided by the weight
of the total sample shall be determined and multiplied by 100. This shall be the percent dry weight of the foreign matter content. Recordkeeping will conform to provisions detailed
in .1408 (b) and (c).
