Abstract
AbstractThe purpose of this investigation was to assess the groundwater impact of irrigation with industrial wastewater (baker's yeast wastewater, BYW) and to determine if agricultural reuse can be considered as an efficient wastewater treatment method. The impact of the irrigation and the status of the groundwater quality were determined using chemical parameters that are typical contaminants of BYW and characterise the content of total suspended solids (TSSs), organic matter (biochemical and chemical oxygen demands), nutrients (Norg, N‐NH4, N‐NO3, Ntotal, Ptotal and K), salts (Cl, SO4 and Na) and pH. The study revealed that BYW irrigation did not cause a significant increase in the content of these parameters in groundwater at a low water table region (WTR). However, at a high WTR, the irrigation had an extremely significant (P < 0.001) impact on the chemical status of groundwater that has been demonstrated by substantially high values of COD, N‐NH4, Cl, SO4 and Na.
