The concentra.ions of MCB in the Ga. column effluent a.d.TCE in the Fe^0 column effluent were below the d.tection limit. However, the concentra.ions of MCB a.d.TCE in the fina. ca.cite column exceed.d.the ma.imum conta.ina.t level （MCL） und.r the Sa.e d.inking Wa.er a.t of the US Environmenta.

We present a.ped.0}ogica. overview of the nonperturba.ive mecha.ism tha. end.ws gluons with a.d.na.ica. ma.s. This a.a.ysis is performed.ba.ed.on pure Ya.g-Mills theories in the La.d.0} ga.ge, within the theoretica. fra.ework tha. emerges from the combina.ion of the pinch technique with the ba.kground.field.method. In pa.ticula., we concentra.e on the Schwinger-d.son equa.ion sa.isfied.by the gluon propa.a.or a.d.exa.ine the necessa.y cond.tions for obta.ning finite solutions within the infra.ed.region. The role of sea.ull d.a.ra.s receives pa.ticula. a.tention, a. d. the id.ntities tha. enforce the ca.cella.ion of a.l potentia. qua.ra.ic d.vergences. We stress the necessity of introd.cing nonperturba.ive ma.sless poles in the fully d.essed.vertices of the theory in ord.r to trigger the Schwinger mecha.ism, a.d.expla.n in d.ta.l the instrumenta. role of these poles in ma.nta.ning the Becchi-Rouet-Stora.Tyutin symmetry a. every step of the ma.s-genera.ing proced.re.
