Bioattenuation is most sensitive to spatial variations in incipient biomass and critical electron donors/acceptors for ω ≥ 1 (i.e., when pore-water residence times are high compared to the time needed for microbial growth or contaminant attenuation). Under these conditions, critical reaction processes can become substrate-limited at multiple locations throughout the aquifer; which in turn increases expected contaminant discharges and their uncertainties at monitored transects. For ω ≤ 0.2, contaminant discharge is not sensitive to incipient biomass variations. Physical heterogeneities expedite plume arrival and delay departure at transects and in turn attenuate peak discharges but do not affect cumulative contaminant discharges. Physical heterogeneities do, however, induce transect mass discharge variances that are bimodal functions of time; the first peak beings consistently higher. A simple stream tube model is invoked to explain the occurrence of peaks in contaminant discharge variance.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2013-08-26T15:40:42Z No. of bitstreams: 1 1-s2.0-S0309170810000825-main.pdf: 838769 bytes, checksum: af48ec7aa13521cdc1101e67f7977c2a (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2013-11-01T11:51:26Z (GMT) No. of bitstreams: 1 1-s2.0-S0309170810000825-main.pdf: 838769 bytes, checksum: af48ec7aa13521cdc1101e67f7977c2a (MD5)Made available in DSpace on 2013-11-01T11:51:26Z (GMT).
