“…In an investigation in Serbia by Fridrich et al (2014), the effects of treated animal wastewater application (from 3 IHFOs with 3000 AU each) in lagoons without hydroisolation for storing wastewaters, where the water table is *5 m, were studied. Average concentrations of COD and BOD 5 ranged between 17-46 mg COD L -1 and 3.7-10.8 mg BOD 5 L -1 , respectively.…”

The application of treated animal wastewater produced in intensive fog farming operations (IHFOs) on surface soil, leads to groundwater contamination. In this study, the contamination of a Mediterranean aquifer caused by long-term application of treated wastewater, produced by an IHFO, on a plot with a geologic fault within the IHFO boundaries, was investigated. Groundwater samples were taken from monitoring wells close to the IHFO. A significant increase of chemical oxygen demand (COD), biochemical oxygen demand (BOD5), total viable count (TVC) and total coliform (TC) concentrations was found in wells, compared to control monitoring well, which were mainly affected by the subsurface flow of contaminated water, due to the presence of the geologic fault. During the winter, significant increases in concentrations of COD, BOD5, TVC and TC were noted and attributed to increased precipitation, which assisted in the accelerated transport of organic compounds and microbial load, through geologic fault, to groundwater.

“…In order to eliminate the risk related to disease transfer, water intended for mass consumption is treated and disinfected before use. Monitoring of water sources involves the determination of important microbiological and physico-chemical parameters which indicate first of all potential organic pollution, particularly pollution originating from animal excrement, storage of waste, natural and artificial fertilisers, and others (Sasakova et al 2013;Fridrich et al 2014). On the basis of the results, adequate measures can be taken that include prevention of contamination and systemic disinfection.…”

ABSTRACT:The aim of this study was to examine drinking water on three farms in eastern Slovakia and to determine experimentally the optimum dose for adequate disinfection in terms of devitalisation of potential pathogens while observing the limit for residual active chlorine (0.3 mg/l) in drinking water. Our investigations included bacteriological examination focused on general contamination and indicator bacteria (bacteria cultivated at 22 and 37 °C, total coliforms, E. coli, enterococci), physico-chemical examination (pH, ammonium ions, nitrites, nitrates, chlorides, free chlorine, chemical oxygen demand COD Mn and Ca + Mg), and EEM (excitation emission matrix) fluorescence spectroscopy which focused on the presence of natural organic matter (NOM). After determining the optimum single dose of Chloramine T for disinfection of water used for watering of animals, the bacteriological quality of water was checked on the 5 th day after the disinfection. The results showed that water quality was better on Farm No. 3 than on Farms No. 1 and No. 2. The weather (precipitation) evidently affected the quality of water on all three farms and was associated with some risk to animals consuming this water. The experimentally determined doses of Chloramine T appeared relatively efficient on Farm No. 1 and Farm No. 3, while the Chloramine T dose estimated for adequate disinfection on Farm No. 2 had to be increased considerably but was still much lower than the dose recommended by the manufacturer of this preparation. It appeared effective to adjust the intervals between individual chlorine treatments according to weather conditions (heavy rain) instead of increasing the active chlorine dose.

“…They may survive in water for different periods of time depending on many factors. Monitoring of safety of water sources is based on determination of parameters that indicate pollution caused by sewage, animal excrements, storage of waste, animal manure and artificial fertilizers, and other (Sasakova et al, 2013;Fridrich et al, 2014). An important tool that helps to eliminate pollution of water sources is the Directive 2010/75/EU on integrated prevention of pollution and control that applies to industrial and agricultural installations with large pollution potential.…”

The objective of this study was to monitor the quality of ground water supplied to animal farms and 2 villages and of surface water (rivers) in the same area (Košice basin, eastern Slovakia) with the aim to assess contamination of water by potential sources in this area. Samples for physico-chemical and microbiological examination were collected at 12 sampling points (6-surface water; 6-ground water) from May 2014 up to March 2015, covering all four seasons. The examination and evaluation of individual parameters was carried out according to relevant Slovak legislation compatible with EU Drinking water directive. The physico-chemical evaluation focused on parameters that indicate pollution of water resulting from human activities and farming. Microbiological examination included determination of counts of bacteria cultivated at 22 • C and 37 • C (BC22 and BC37), total coliforms, E. coli and fecal streptococci. Ground water intended for mass consumption (farms, villages) is abstracted from wells, collected in storage reservoirs and disinfected before brought to consumers. Some families in the villages use their own wells. Water for individual consumption (individual households) originates directly from individual wells. Examination of potable water used on agricultural farms showed some possibility of contamination of sources by runoff and inappropriate manipulation with excrements. Surface water in in the area close to both farms was polluted with organic substances (COD Mn ), however they did not exceed the limit set for surface water. At many samplings we detected in surface water presence of total coliforms, E. coli and occasionally also fecal enterococci indicating fecal pollution that could eventually affect ground water in individual wells. Our investigations showed that protection zones of water sources were not always sufficient. There were considerable variations in the quality of surface water during the year but no clear relationship between microbial contamination and seasons was observed. Quality of ground water supplied for mass consumption complied with legislative regulations except for BC 22 (heterotrophic count at 22 • C) in summer and autumn). Water from individual wells contained occasionally presence of total coliforms, E. coli and enterococci and higher heterotrophic counts.
