Available in PDF, EPUB and Kindle. Book excerpt: Water treatment residuals (WTR) and biosolids are by-products from municipal treatment processes. Both products have been studied separately for their benefits on land application as an alternative method of beneficial reuse. WTR land application concern is the amorphous metal oxides adsorbing tremendous P amounts, thus significantly reducing plant-available P via surface adsorption. A supplemental P source, such as biosolids, should negate the adsorptive effects. Co-application effects in terms of P fractionation have not been studied. The objectives of the project were to understand both the long-term effects of a single co-application of biosolids and water treatment residuals (WTR) and the short-term impacts of a repeated co-application on soil inorganic and organic P dynamics. Test plots were 7.5 × 15 m with treatments consisting of three different WTR rates co-applied with a single biosolids rate (0, 10, and 21 Mg WTR ha-1 coapplied with 10 Mg biosolids ha-1) in either 1991 or 2002. Soil samples were collected in 2003 and 2004 from the 0-5-cm depth within each plot. Soils were analyzed for pH, EC, total C and N, inorganic C, soluble/loosely bound P, Al-P, Fe-P, occluded-P, Ca-P, labile organic P, microbial biomass P, humic and fulvic acid P, resistant organic P, oxalate extractable P, Al, Fe, and phosphorus saturation index, Mehlich-III, Bray-I, and Olsen’s extractable P. Comparisons were made between all inorganic and organic P fractions to identify P cycling in the system over time.

Available in PDF, EPUB and Kindle. Book excerpt: The 1993 regulation (Part 503 Rule) governing the land application of biosolids was established to protect public health and the environment from reasonably anticipated adverse effects. Included in the regulation are chemical pollutant limits, operational standards designed to reduce pathogens and the attraction of disease vectors, and management practices. This report from the Board on Environmental Studies and Toxicology evaluates the technical methods and approaches used by EPA to establish those standards and practices, focusing specifically on human health protection. The report examines improvements in risk-assessment practices and advances in the scientific database since promulgation of the regulation, and makes recommendations for addressing public health concerns, uncertainties, and data gaps about the technical basis of the biosolids standards.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Application of biosolids on agricultural lands is a common practice and useful disposal alternative for recycling organic matter and nutrients into soils, as a replacement for synthetic fertilizers. There is a need to better understand potential environmental implications from the application of these soil amendments to ensure that they can be applied without negative impacts on the underlying aquifer. In particular, the relationship between biosolids application rates and resulting concentrations of pharmaceuticals and nitrate in aquifers requires further investigation. The main research objectives were to identify potential impacts of biosolids application on groundwater quality in a shallow sedimentary fractured bedrock aquifer, looking at both temporal and spatial variability, and to determine whether tile drainage systems affect the leaching of those contaminants to the aquifer. The depth-discrete monitoring approach captured distinct insights on water quality and contaminant behaviour, and facilitated the examination of vertical variability of emerging substances of concern (ESOC) and nitrate concentrations within the borehole. In addition, a bromide tracer experiment was used to aid in the characterization of the groundwater flow and solute travel times from the surface to the aquifer. Results suggested the system is more sensitive to surface-applied compounds in summer and spring, where warmer temperatures seemed to facilitate N mineralization, yet biosolids application may not pose a risk to groundwater quality on the short term, for this hydrogeological setting. Predominance of lateral movement observed at the site affects the fate of contaminants in the subsurface. Additionally, tile systems might be intercepting contaminant pathways, influencing the transport and fate of the leached hydrophilic compounds from the surface. The results are relevant for the implementation of local water protection policies through the development of standards or guidelines to avoid harm from biosolids application, and should be considered by specialists when recommending ideal agronomic loading rates of biosolids for agricultural soil amendments.

This book was released on 2015 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study is an objective evaluation of the controversy on whether the practice of land application of biosolids for soil enrichment and restoration poses significant harm to the environment, human and animal health. Over the years, many review articles have concluded that the majority of research show that the practice poses less harm as compared to the benefits. This in turn made the United States Environmental Protection Agency to promote its use for soil enrichment and restoration. In an attempt to obtain an objective evaluation, based on reliable scientific evidence of the controversy, Google Scholar search was conducted using the phrase "environmental and health effects of land application of sewage sludge/biosolids". The search result yielded 86 research articles directly related to the topic. The 86 articles were then comprehensively studied and grouped into three categories: those research findings that proved that land application of biosolids poses significant harm to the environment, human and animal health, those that proved that the practice does not pose significant harm to the environment, human and animal health and those that were inclusive and suggest precaution in using biosolids for soil enrichment and restoration. iv Out of the total of 86 research articles studied, 42 or about 49% found that land application of biosolids posed significant harm to the environment, human and animal health as opposed to 33 or about 38% concluding no significant harm. Furthermore, when research conducted in the U.S. were extracted from the 86 global research articles, about 51% found that land application of biosolids posed significant harm to the environment, human and animal health as opposed to about 36% concluding no significant harm. The U.S. articles numbered 47 or about 55% of the total articles reviewed. Based on these statistics from the current study, it is evident that majority of the studies conducted over the past 15 years suggest that land application of biosolids for soil enrichment and restoration poses significant harm to the environment, human and animal health.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Biosolids, or composted sewage sludge, are a relatively untapped but broadly available resource, and the repository for a substantial portion of nutrients consumed in the form of food. Returning these nutrients to food production systems would "close the loop" in nutrient cycling rather than cause a waste disposal problem. Biosolids have the potential to be a beneficial soil amendment to agricultural land, yet in addition to nutrients they also ubiquitously contain contaminants such as pharmaceuticals and personal care products (PPCPs). Biochar, or pyrolyzed agricultural waste, is a potential co-amendment with biosolids that could reduce the bioavailability of pharmaceuticals found in biosolids. Because of its unique chemistry and high surface area, biochar can sorb organic chemicals such as PPCPs that are introduced to the soil via application of biosolids. The major objectives of this work were to understand effects of contaminants found in biosolids on soil ecosystem processes and related microbial structure, and to examine how biochar affects these relationships. These were addressed in two separate studies: (1) In a laboratory soil incubation, we show that functional redundancy between ammonia-oxidizing bacteria (AOB) and archaea (AOA) can buffer negative effects of exposure to ciprofloxacin, an antibiotic commonly found in biosolids. The higher resistance, at least in the short-term, of AOA to antibiotics can maintain the process rate of nitrification, providing ecosystem functional resistance to the antibiotic disturbance. Further, co-amending with biochar mitigates any negative effect of ciprofloxacin on either AOB or AOA, suggesting that biochar can be an effective sorbent of pharmaceutical contaminants. (2) In a greenhouse study examining the effects of co-amending biosolids with biochar, we find that biochar has positive growth effects on plants, possibly due to the aforementioned sorption of growth-limiting contaminants found in biosolids. However, a bioanalytical (CALUX) examination of endocrine-disrupting activity in the biosolid- and biochar-amended soils suggests that biochars might also be a source of such activity. The rate of biochar application to induce this effect (100 t ha−1) is high above the average agronomic rate (10 t ha−1), and it is thus possible that such levels of endocrine-disrupting activity would not be present in the soil in an agricultural context. Together, these results show how microbial communities and related functions are affected by contaminants in biosolids, and suggest that biochar might be an effective co-amendment to mitigate negative effects of an antibiotic disturbance. However, biochar must be explored for potential environmentally-relevant endocrine-disrupting activity before it is used as a remediation tool.
