 is in contact with the acid solution in the bottle. Tightly seal the
parafilm around the outlet tubing.
C. Sample collection procedure.
a. Collect leachate samples at a prescribed frequency. Recommended
frequency is provided in the Sample Collection Chart in Table D1.
b. After collection, replace the lid, carefully mix the leachate sample, and
reweigh. Determine the weight of sample collected, by difference, and
record this weight.
c. Insert a polyethylene stirring rod in the sample, and check the pH of the
sample with pH paper. If the pH of the sample is greater than 2, add
concentrated Ultrex nitric acid in 0.1-mL increments until the pH is less
than 2.
d. For chloride determination, weigh 40 g of leachate sample into a 60-mL
polyethylene bottle. Label the bottle with the sediment identification,
column leach apparatus number, sample number, and parameter code.
Store samples at 4 EC.
