The disclosed embodiments provide a system that facilitates use of a network link. The generation method includes: receiving a variable length coding table; and dynamically establishing an adaptive decoding lookup table from the VLC table according to a target decoding rate and a free system memory resource. The processes may be applied on a batch or continuous basis to contaminated soil and groundwater, to contaminated effluents from a wide variety industrial operations, or to wherever such amenable contaminants are present. For 14 rate, the LDPC code has the following relevant parameters: q=135, nldpc=64,800, kldpc=nBCH=16200, kBCH=16008.
