Table 3

Characteristic of “old” landfill leachate (nondiluted).

Parameter	Unit	Range	Average±SD^∗	Median
TOC	mg/L	309–352	327±21	324
COD	mg/L	381–435	403±19	400
BOD	mg/L	120–150	134±11	130
N NH4	mg/L	26–60	43±10	52

^∗SD: standard deviation; number of measurements𝑛=16; time-dependent variation of parameters value was caused by unstable composition of leachate.
