“…2), were negligible for both pig slurry and DSW (<1%), but were also very low for dairy slurry (average 2.5%). These low levels are consistent with the findings of Bolado-Rodríguez et al (2010), who measured just 0.3 g TOC in leachate from air stripped pig slurry compared with 3.5 g applied in a soil column experiment.…”

This study aimed to quantify leaching losses of nitrogen (N), phosphorus (P) and carbon (C), as well as carbon dioxide (CO) and methane (CH) emissions from stored slurry, and from packed soil columns surface applied with unamended and chemically amended dairy and pig slurries, and dairy soiled water (DSW). The amendments to the slurries, which were applied individually and together, were: polyaluminum chloride (PAC) and zeolite for pig and dairy slurry, and liquid aluminium sulfate (alum) and zeolite for DSW. Application of pig slurry resulted in the highest total nitrogen (TN) and nitrate-nitrogen (NO-N) fluxes (22 and 12 kg ha), whereas corresponding fluxes from dairy slurries and DSW were not significantly (p < 0.05) higher than those from the control soil. There were no significant (p < 0.05) differences in leachate N losses between unamended and amended dairy slurries, unamended and amended pig slurries, and unamended and amended DSW. There were no leachate P losses measured over the experimental duration. Total cumulative organic (TOC) and inorganic C (TIC) losses in leachate were highest for unamended dairy slurry (82 and 142 kg ha), and these were significantly (p < 0.05) reduced when amended with PAC (38 and 104 kg ha). The highest average cumulative CO emissions for all treatments were measured for pig slurries (680 kg CO-C ha) followed by DSW (515 kg CO-C ha) and dairy slurries (486 kg CO-C ha). The results indicate that pig slurry, either in raw or chemically amended form, poses the greatest environmental threat of leaching losses and gaseous emissions of CO and CH and, in general, amendment of wastewater with PAC, alum or zeolite, does not mitigate the risk of these losses.

“…The area studied has 170 farms distributed in an approximated surface of 1000 square miles, generating a total amount of 1 million of tones of slurries at year (source: EUROSTAT DATABASE, 2009) of 41 million of tones at year generated in EU. The management of these products turns out to be complicated and inefficient, constituting an environmental and sanitary problem because of zoonotic pathogens like HEV, may be transported to drinking water resources (Bolado-Rodriguez et al, 2010;Hazam et al, 2010;Meng, 2011) and other problems like excessive nitrification of soil and presence of excessive concentra-tion of heavy metals. These problems worry both the livestock sector and Public Health authorities.…”

Hepatitis E virus (HEV) is an increasing cause of acute hepatitis in industrialized countries. The aim of this study was to evaluate the presence of HEV in pig manure composting plants located in Spain. For this purpose, a total of 594 samples were taken in 54 sampling sessions from the different stages of composting treatment in these plants as follows: slurry reception ponds, anaerobic ponds, aerobic ponds, fermentation zone and composting final products. HEV was detected by reverse transcription polymerase chain reaction (RT-nested PCR) in four (80%) of five plants studied, mainly in the first stages of the process. HEV was not detected in any final product (compost) sample, destined to be commercialized as a soil fertilizer, suggesting that composting is a suitable method to eliminate HEV and thus, to reduce the transmission of HEV from pigs to humans.

“…Chemical treatment of slurry may also have an effect on the survival of microorganisms (31) and on the size distribution of slurry particles. Investigating the effect of slurry pretreatment on the leaching potential of manure-borne contaminants is, therefore, important (32).…”

Pathogens may reach agricultural soils through application of animal manure and thereby pose a risk of contaminating crops as well as surface and groundwater. Treatment and handling of manure for improved nutrient and odor management may also influence the amount and fate of manure-borne pathogens in the soil. A study was conducted to investigate the leaching potentials of a phage (Salmonella enterica serovar Typhimurium bacteriophage 28B) and two bacteria, Escherichia coli and Enterococcus species, in a liquid fraction of raw pig slurry obtained by solid-liquid separation of this slurry and in this liquid fraction after ozonation, when applied to intact soil columns by subsurface injection. We also compared leaching potentials of surface-applied and subsurface-injected raw slurry. The columns were exposed to irrigation events (3.5-h period at 10 mm h ؊1 ) after 1, 2, 3, and 4 weeks of incubation with collection of leachate. By the end of incubation, the distribution and survival of microorganisms in the soil of each treatment and in nonirrigated columns with injected raw slurry or liquid fraction were determined. E. coli in the leachates was quantified by both plate counts and quantitative PCR (qPCR) to assess the proportions of culturable and nonculturable (viable and nonviable) cells. Solid-liquid separation of slurry increased the redistribution in soil of contaminants in the liquid fraction compared to raw slurry, and the percent recovery of E. coli and Enterococcus species was higher for the liquid fraction than for raw slurry after the four leaching events. The liquid fraction also resulted in more leaching of all contaminants except Enterococcus species than did raw slurry. Ozonation reduced E. coli leaching only. Injection enhanced the leaching potential of the microorganisms investigated compared to surface application, probably because of a better survival with subsurface injection and a shorter leaching path.
