Inthepresentstudy,8samples(3Yamunawatersamples,3tanneryeffluentsamplesand2textileeffluentsamples),werecollectedfromdifferentsitesofYamunaandexitpointsoftextileandtanneryIndustries.

IntroductionTheparamountofpollutioninourenvironmentespeciallyrivers,isadireconsequenceofcontinuallyexpandingpopulationalongwithanexponentialdevelopmentintheindustrialfield.
RiverYamuna,withatotallengthofaround1370kmisthelargesttributaryoftheGanges.
ThepollutionofriverYamunaisconsideredaninternationalissue.
Therearemanybigindustries,factories,andevenpeopleslivingincolonies,slumsandruralareasatthebankofYamuna.
Allthesearepollutingthisriver.
Amongthesecauses,industriesarecontributingmajorlytoincreasepollutionloadinriverYamunaespeciallytanneriesandtextileprintingunits.
ThetanningindustryplaysasignificantroleinIndianeconomybygeneratingexportsandemployment.
However,tannerywastesareamongthehighestpollutantindustrialwastes.
Tannerywasteisalwayscharacterizedbyitsstrongcolour(reddishdullbrown),highBOD,highpH,andhighdissolvedsolids.
Importantpollutantsassociatedwiththetanningindustryincludechlorides,tannins,chromium,sulphateandsulphidesasadditiontotraceorganicchemicalsandincreasinguseofsyntheticchemicalssuchaspesticides,dyesandfinishingagents,aswellasfromtheuseofnewerprocessingchemicalsolvents(Chandravathanam,2009).
Ithasbeenrecognizedtointerruptagro-basedactivitieslikefarmingandanimalhusbandryaswellaspolluteground-watersystems.
Groundwatercontaminationoccurswhenwastewaterandchemicalsseepthroughthesoilfromunlinedponds,pipesanddrains,orfromdumpsandspills.
Groundwatermaytakealongtimetocleanseitselfbecauseitmovesslowlyandisoutofcontactwithair.
Consequentlywhenthedepositionofsolidsisconsidered,itbecomesapparentthatrawunsettledtannerywastewaterscancauseencrustation(ofcalciumcarbonate)andseriouscorrosionofmetalsaswellasconcretesewers(duetoH2SbiologicaloxidationtoH2SO4)(Balusubramanianetal.
