This paper describes a software platform for water environment monitoring. The main monitored parameters are temperature, turbidity, PH, dissolved oxygen, chemical oxygen demand (COD), total phosphorus, total nitrogen, nitrogen ammonia (NH) and heavy metal such as Pb, Zn and Cu etc. This platform was designed using java language and java web technology, which are widely used in many software platforms including water environment monitoring. Low cost and lightweight framework are the major aspects of the software platform because free software (Tomcat and MySQL) and SSH framework are adopted in this software platform. People can view water quality data in a computer or a smart phone browser in the form of table and chart. The water quality data transmitted from General Packet Radio Service (GPRS) wireless network are stored into the MySQL database automatically once the software platform is started. Data collected by this platform is real-time, once a record is out of limits, a message will be sent to mobile phone. Through data collected, environment protection administrators can predict and get the conclusion whether the water is polluted or not.

A water environmental monitoring system based on a wireless sensor network is proposed. It consists of three parts: data monitoring nodes, data base station and remote monitoring center. This system is suitable for the complex and large-scale water environment monitoring, such as for reservoirs, lakes, rivers, swamps, and shallow or deep ground waters. This paper is devoted to the explanation and illustration for our new water environment monitoring system design. The system had successfully accomplished the online auto-monitoring of the water temperature and pH value environment of an artificial lake. The monitoring system thus promises broad applicability prospects. The system's measurement capacity ranges from 0 to 90 °C for water temperature, with an accuracy of ±0.5 °C; from 0 to 16 on pH value, with an accuracy of ±0.05 pH units. Sensors applicable to different water quality scenarios should be installed at the nodes to meet the monitoring demands for a variety of water environments and to obtain different parameters.

Article contains theoretical and practical technical sentences on creation of an optoelectronic complex of monitoring of emergency discharge of pollution in sewage of the enterprises.The relevance of the task of monitoring of sewage on existence of emergency clots in sewage for saving water sources is shown. The structural scheme of a complex of monitoring of the water environment is provided. The mathematical model of a complex of optoelectronic monitoring over the water environment on the example of sewage of the enterprise is considered. The complex of monitoring is described by the random impulse transition function containing two independent components, one of which defines dynamic properties, another considers stochasticity of conversion.The example of implementation of an optoelectronic complex of monitoring of the water environment in the system of sewage of the enterprise is given. Experimentally the efficiency of a complex in case of measurement of changes of optical density of the analysable environments is shown. For carrying out an experiment water pollution is selected by vegetable oil. The analysis of absorption spectra of water and vegetable oil showed that as a source of radiation it is expedient to use lasers with lengths of waves in the range of 0,4–0,5 μm which have the minimum absorption of radiation in the water environment and the considerable absorption in the environment of impurity, for example, the violet STLL-MM-405-200-52-A laser with wavelength of 0,405 μm and 200 mW. As the photo-sensor element, it is possible to use, for example, the PDV-V400-46 photodiode.Results of an experiment of a research of optical density of the liquid environment containing clots from vegetable oil are given. They show the functional connection of pollution of sewage with change of optical density of the water environment with certain lengths of waves of a probing laser radiation.

The aim of this report is to contribute to the base of knowledge on environmental monitoring by increasing understanding of how eDNA, electrofishing and sampling fishing may be used to examine fish biodiversity. It also aims at understanding if fish indexes developed within the Water Framework Directive reflect biodiversity, as well as the potential of eDNA data to serve as input to these indexes. This was done by using three different approaches. Firstly, in order to establish which of the methods eDNA, electrofishing and sampling fishing is more suitable to measure the different dimensions of biodiversity (species richness, species evenness and genetic diversity), a literature review comparing the different methods was carried out. It was found that eDNA yields a more detailed results for species richness, electrofishing yields better results for species evenness and sampling fishing is outperformed by eDNA and electrofishing alike. Both electrofishing and sampling fishing may collect data for genetic diversity analysis, however electrofishing outperforms sampling fishing with regards to amount of species caught, making electrofishing a more suitable data collection method. Secondly, in order to gain insight on practical usage of eDNA, a case study of Spjutmo (Dalarna county) was reviewed. It was established that eDNA generated more detailed information of species richness in the case of Spjutmo (as compared to electrofishing). The relative abundance data generated by the eDNA study might be seen as a measure of species evenness. However, electrofishing yielded data which may serve as input to species evenness indices. To the best knowledge of the author, none of the methods generated data on genetic diversity in this specific case. Officials from the energy company Fortum and the county board of Dalarna were also interviewed in order to get insight on what potential they see for eDNA to contribute to environmental monitoring. Both officials point at the ability to estimate abundance as a desired feature, hence a better understanding of what the relative abundance results indicates is wanted. The two interviews indicate that this understanding is an important feature to develop in order to make metabarcoding studies effective in current environmental monitoring. Thirdly, in order to understand if fish indexes developed within the Water Framework Directive reflect biodiversity, a literature review was performed. It was found that, all but one of the compared indexes incorporates or somewhat incorporates species richness. However, only five indexes are indicative or somewhat indicative of species richness. Species evenness is incorporated or somewhat incorporated by two indexes, which are also indicative or somewhat indicative of species evenness. None of the indexes incorporate or indicate genetic diversity. Within the third literature review, the potential of eDNA data to serve as input to current fish-based indexes developed within the Water Framework Directive, was studied. It was found that eDNA data may serve as input to only one index in its present form. However, five indexes also use proportional information (e.g. proportion of tolerant species), which possibly could be provided by eDNA data. The index where usage of eDNA data is currently possible uses presence-absence information.
Målet med denna rapport är att bidra till kunskapsläget kring miljöövervakning genom att öka förståelsen för hur eDNA, elfiske och provfiske kan användas för att undersöka fisk biodiversitet. Målet är också att förstå om fisk-index utvecklade inom ramen för det Europeiska vattendirektivet reflekterar biodiversitet samt om data från eDNA kan utgöra input till dessa index. För att uppfylla dessa mål användes tre metoder. För att etablera vilken av metoderna eDNA, elfiske och provfiske är mer lämpad att mäta de olika dimensionerna av biodiversitet (artrikedom, distribution av arter och genetisk diversitet), genomfördes en litteraturstudie. Slutsatsen kunde dras att eDNA mäter artrikedom med högst noggrannhet, elfiske mäter distribution av arter mer detaljerat och att provfiske överträffas av både eDNA och elfiske i alla dimensioner. Både elfiske och provfiske kan samla data för analys av genetisk diversitet, men elfiske överträffar provfiske gällande hur många arter som fångas, vilket gör elfiske mer lämpligt som metod att samla in data för genetisk analys. För att få praktisk insikt i ett fall där eDNA använts, granskades en fallstudie från Spjutmo (i Dalarnas län). eDNA genererade mer detaljerad information om artrikedom än elfiske i detta fall. Datan genererad av eDNA kring relativ abundans mellan arter skulle kunna tolkas som ett mått på distribution av arter. Data genererad av elfiske kan å andra sidan användas som input till olika index för distribution av arter. Författaren veterligen, genererade varken eDNA eller elfiske mått på genetisk diversitet i detta specifika fall. Två personer, en från Fortum och en från länsstyrelsen Dalarna intervjuades också för att få insikt i deras syn på potentialen av att använda eDNA som ett miljöövervakningsverktyg. Båda intervjupersonerna pekade på att en bättre förståelse av de relativa abundansvärdena indikerar är önskad. Båda intervjupersonerna pekade på att det är en viktig aspekt för att metabarcoding studier ska vara effektiva i nuvarande miljöövervakning. För att förstå om fisk-index utvecklade för EU’s vattendirektiv reflekterar biodiversitet, genomfördes en komparativ litteraturstudie av index. Alla index förutom ett inkorporerar eller delvis inkorporerar artrikedom. Bara fem indikerar eller delvis indikerar artrikedom. Distribution av arter inkorporeras eller delvis inkorporeras av två index som också indikerar eller delvis indikerar distribution av arter. Inom den komparativa litteraturstudien av index, studerades även potential att fungera som input av data genererad av eDNA till indexen. Data genererad av eDNA kan i dagsläget fungera som input till ett av indexen. Fem index använder någon form av proportionell data (t.ex. proportion av toleranta arter), som möjligen skulle kunna ges av eDNA. Indexet till vilket det är möjligt att använda eDNA data använder närvarande-ej närvarande information som input.

Originally developed in the 1970s for the optimal control of systems governed by partial differential equations, the adjoint method has found several successful applications, e.g. in meteorology with large-scale 3D or 4D atmospheric data assimilation schemes, for carbon cycle data assimilation in biogeochemistry and climate research, or in oceanographic modelling with efficient adjoint codes of ocean general circulation models.

Despite the variety of applications in these research fields, adjoint methods have only very recently drawn attention from the ocean acoustics community. In ocean acoustic tomography and geoacoustic inversion, where the inverse problem is to recover unknown acoustic properties of the water column and the seabed from acoustic transmission data, the solution approaches are typically based on travel time inversion or standard matched-field processing in combination with metaheuristics for global optimization.

In order to complement the adjoint schemes already in use in meteorology and oceanography with an ocean acoustic component, this thesis is concerned with the development of the adjoint of a full-field acoustic propagation model for shallow water environments.

In view of the increasing importance of global ocean observing systems such as the European Seas Observatory Network, the Arctic Ocean Observing System and Maritime Rapid Environmental Assessment (MREA) systems for defence and security applications, the adjoint of an ocean acoustic propagation model can become an integral part of a coupled oceanographic and acoustic data assimilation scheme in the future.

Given the acoustic pressure field measured on a vertical hydrophone array and a modelled replica field that is calculated for a specific parametrization of the environment, the developed adjoint model backpropagates the mismatch (residual) between the measured and predicted field from the receiver array towards the source.

The backpropagated error field is then converted into an estimate of the exact gradient of the objective function with respect to any of the relevant physical parameters of the environment including the sound speed structure in the water column and densities, compressional/shear sound speeds, and attenuations of the sediment layers and the sub-bottom halfspace. The resulting environmental gradients can be used in combination with gradient descent methods such as conjugate gradient, or Newton-type optimization methods tolocate the error surface minimum via a series of iterations. This is particularly attractive for monitoring slowly varying environments, where the gradient information can be used to track the environmental parameters continuously over time and space.

In shallow water environments, where an accurate treatment of the acoustic interaction with the bottom is of outmost importance for a correct prediction of the sound field, and field data are often recorded on non-fully populated arrays, there is an inherent need for observation over a broad range of frequencies. For this purpose, the adjoint-based approach is generalized for a joint optimization across multiple frequencies and special attention is devoted to regularization methods that incorporate additional information about the desired solution in order to stabilize the optimization process.

Starting with an analytical formulation of the multiple-frequency adjoint approach for parabolic-type approximations, the adjoint method is progressively tailored in the course of the thesis towards a realistic wide-angle parabolic equation propagation model and the treatment of fully nonlocal impedance boundary conditions. A semi-automatic adjoint generation via modular graph approach enables the direct inversion of both the geoacoustic parameters embedded in the discrete nonlocal boundary condition and the acoustic properties of the water column. Several case studies based on environmental data obtained in Mediterranean shallow waters are used in the thesis to assess the capabilities of adjoint-based acoustic inversion for different experimental configurations, particularly taking into account sparse array geometries and partial depth coverage of the water column. The numerical implementation of the approach is found to be robust, provided that the initial guesses are not too far from the desired solution, and accurate, and converges in a small number of iterations. During the multi-frequency optimization process, the evolution of the control parameters displays a parameter hierarchy which clearly relates to the relative sensitivity of the acoustic pressure field to the physical parameters.

The actual validation of the adjoint-generated environmental gradients for acoustic monitoring of a shallow water environment is based on acoustic and oceanographic data from the Yellow Shark '94 and the MREA '07 sea trials, conducted in the Tyrrhenian Sea, south of the island of Elba.

Starting from an initial guess of the environmental control parameters, either obtained through acoustic inversion with global search or supported by archival in-situ data, the adjoint method provides an efficient means to adjust local changes with a couple of iterations and monitor the environmental properties over a series of inversions.

In this thesis the adjoint-based approach is used, e.g. to fine-tune up to eight bottom geoacoustic parameters of a shallow-water environment and to track the time-varying sound speed profile in the water column.

In the same way the approach can be extended to track the spatial water column and bottom structure using a mobile network of sparse arrays.

Work is currently being focused on the inclusion of the adjoint approach into hybrid optimization schemes or ensemble predictions, as an essential building block in a combined ocean acoustic data assimilation framework and the subsequent validation of the acoustic monitoring capabilities with long-term experimental data in shallow water environments.

The impact of multiple anthropogenic stressors on the marine environment has increased to large extents within the past few decades. Piscivorous fish can bioaccumulate pollutans to significantly higher concentrations than those found in the water or sediments, due to the lipid solubility and resistance of these compounds to numerous degenerative processes. The use of fish from different hydrological settings as bio-indicators represents a useful complementary choice to evaluate the levels and responses of marine organisms to pollutans, and to assess the global marine status. The purpose of this project is to evaluate the role of selected pelagic (Thunnus thynnus), and benthopelagic fish species (Dentex dentex and Pagellus bogaraveo) as biomonitors of Mediterranean sea pollution through the chemical identification and quantification of persistent organic and inorganic compounds in target tissues, the investigation of toxicopathic-related pathological changes, and the putative correlation between abnormal levels of pollutants and tissue lesions. Fish were selected based on length and weight. The mean concentration of metallic elements, polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCs) was calculated and compared to their acceptable levels when available. Blackspot seabreams had the highest PCB concentration, whereas OCs were highest in tunas. A different spread in distinct species was documented for the following elements: Al, K, Co, Mo, Ag, Cd, Sn, and Th. For the elements without maximum dietary limits, Fe was highest in tunas, while Th was significantly predominant in dentices. Several metals were found in quantities above the acceptable levels. Specifically, the median concentrations of Hg and Cd in the pooled species were significantly higher than their relative PTWI. Significant differences among species were reported for Se, inorganic As, Ni and Zn. Other elements (Al, Cr, Cu, Sn, Pb, and Mn) were found to be at or below the corresponding acceptable levels. Histopathology evidenced acute and chronic lesions in numerous organs, comprising muscular degeneration and necrosis, hepatic lipidosis, hepatocellular necrosis and dysplastic foci in all fish groups. Specifically, chronic lesions in liver, gills, immune and reproductive systems were common in all fish species encountered. Testicular atrophy, necrotizing branchitis, and proliferation of melanomacrophagic centers represented common findings. Although these findings revealed some differences in the patterns of histopathologic traits between pelagic and benthopelagic fishes, the overall level of histopathological injury was moderate and severe traits like neoplasms or pre-neoplastic foci were not observed. The concentrations of the other metallic elements did not influence the muscular H-indices in all species, with the exception of Na, where the interaction between concentration of Na and fish species was statistically significant. No significant differences were found between the H-indices of different species. Given the simultaneous presence of pollutans in dangerous concentrations and the putative relationship with subacute to chronic microscopic lesions, research on fish contamination and human exposure could not be framed in terms of a single contaminant. Our findings aim to encourage cross-disciplinary discussion and to establish research and monitoring priorities in order to protect the human health. Since the risks associated with high simultaneous levels of multiple compounds have not been quantified but represent a severe health hazard, monitoring data should be collected to characterize the spatial and vertical distribution of metals in seawaters across a range of marine ecosystems. Our work confirms that histopathological evaluation of target organs should be included as a tool to determine the potential consequences of chronic toxicant exposure in wild fish.

Using treated wastewater (TWW) for crop irrigation represents an important opportunity for ensuring adequate food production in light of growing freshwater scarcity worldwide. However, the environmentally sustainable approach of using TWW for irrigation can lead to contamination of produce with fecal pathogens that may remain in treated water. The overall goal of this research was to evaluate the correlation between the presence of fecal indicator bacteria (FIB) and that of a suite of human pathogens in TWW, the irrigated soil, and crops. Field experiments were conducted to compare secondary and tertiary TWW with dechlorinated tap water for irrigation of tomatoes, a typical commercial crop, in Israel, a semi-arid country. Human pathogens including bacteria (Salmonella), protozoa (Cryptosporidiumand Giardia), and viruses (Adenovirus [AV Types A, B, C & 40/41] and Enterovirus [EV71 subtypes]) were monitored in two field trials using a combination of microscopic, cultivation-based, and molecular (qPCR) techniques. Results from the field trials indicate that microbial contamination on the surface of tomatoes did not appear to be associated with the source of irrigated waters; FIB contamination was not statistically different on tomatoes irrigated with TWW as compared to tomatoes irrigated with potable water. In fact, Indicator bacteria testing did not predict the presence of pathogens in any of the matrices tested. High concentrations of FIB were detected in water and on tomato surfaces from all irrigation treatment schemes, while pathogen contamination on tomato surfaces (Cryptosporidiumand Salmonella) was only detected on crops irrigated with TWW. These results suggest that regular monitoring for pathogens should take place to accurately detect presence of harmful microorganisms that could threaten consumer safety. A notable result from our study is that the large numbers of FIB in the water did not appear to lead to FIB accumulation in the soil. With the exception of two samples, E. coli that was present at 10³ to 10⁴ cells/100 mL in the water, was not detected in the soil. Other bacterial targets associated with the enteric environment (e. g., Proteusspp.) as well as protozoal pathogens were detected in the TWW, but not in the soil. These findings suggest that significant microbial transfer to the soil from TWW did not occur in this study. The pattern of FIB contamination on the surfaces of tomatoes was the same for all treatment types, and showed a temporal effect with more contamination detected as the duration of the field trial increased. An important observation revealed that water quality dramatically deteriorated between the time of its release from the wastewater treatment plant and the time it was utilized for irrigation, highlighting the importance of performing water quality testing throughout the growing season at the cultivation site.

This Dredging Operations Environmental Research (DOER) technical note disseminates novel methods to monitor and reduce contaminant mobility and bioavailability in water, sediments, and soils. These method advancements are enabled by additive manufacturing (i.e., three-dimensional [3D] printing) to deploy and retrieve materials that adsorb contaminants that are traditionally applied as unbound powders. Examples of sorbents added as amendments for remediation of contaminated sediments include activated carbon, biochar, biopolymers, zeolite, and sand caps. Figure 1 provides examples of sorbent and photocatalytic particles successfully compounded and 3D printed using polylactic acid as a binder. Additional adsorptive materials may be applicable and photocatalytic materials (Friedmann et al. 2019) may be applied to degrade contaminants of concern into less hazardous forms. This technical note further describes opportunities for U.S. Army Corps of Engineers (USACE) project managers and the water and sediment resource management community to apply 3D printing of polymers containing adsorptive filler materials as a prototyping tool and as an on-site, on-demand manufacturing capability to remediate and monitor contaminants in the environment. This research was funded by DOER project 19-13, titled “3D Printed Design for Remediation and Monitoring of Dredged Material.”

Root water uptake is perhaps the most important unknown in the mass balance of hydrological and agricultural systems. The understanding and the ability to predict root uptake and the way it is influence by environmental conditions has great potential in increasing water and fertilizer use efficiency and allowing better control of water and contaminant leach towards groundwater. This BARD supported research is composed of several components, including a) intensive laboratory work for the quantification of root uptake and the way it is controlled by environmental conditions; b) development of tools for laboratory and field use that can help in sensing very low water fluxes and water content, which is a necessity for studying root uptake; c) development of capabilities to model compensated root uptake; and d) development of a database that will allow calibration of such a model. In addition some auxiliary research was performed as reported later. Some of the components, and especially the modeling and the HPP development, were completed in the framework of the project and even published in the international literature. The completed components provide a modeling environment that allows testing root compensated uptake modeling, a tool that is extremely important for true mechanistic understanding of root uptake and irrigation design that is based on mechanistic and not partially based myth. The new button HPP provides extended level of utilization of this important tool. As discussed below, other components did not get to maturity stage during the period of the project, but comprehensive datasets were collected and will be analyzed in the near future. A comprehensive dataset of high temporal and spatial resolution water contents for two different setups was recorded and should allow us understanding f the uptake at these fine resolutions. Additional important information about root growth dynamics and its dependence in environmental conditions was achieved in both Israel and the US. Overall, this BARD supported project provided insight on many important phenomena related to root uptake and to high resolution monitoring in the vadose zone. Although perhaps not to the level that we initially hoped for, we achieved better understanding of the related processes, better modeling capabilities, and better datasets that will allow continuation of this effort in the near future.

Monitoring water quality of small inland lakes and reservoirs is a critical component of the US Army Corps of Engineers (USACE) water quality management plans. However, limited resources for traditional field-based monitoring of numerous lakes and reservoirs covering vast geographic areas often leads to reactional responses to harmful algal bloom (HAB) outbreaks. Satellite remote sensing methodologies using HAB indicators is a good low-cost option to traditional methods and has been proven to maximize and complement current field-based approaches while providing a synoptic view of water quality (Beck et al. 2016; Beck et al. 2017; Beck et al. 2019; Johansen et al. 2019; Mishra et al. 2019; Stumpf and Tomlinson 2007; Wang et al. 2020; Xu et al. 2019; Reif 2011). To assist USACE water quality management, we developed an Environmental Systems Research Institute (ESRI) ArcGIS Pro desktop software toolbox (waterquality for ArcGIS Pro) founded on the design and research established in the waterquality R software package (Johansen et al. 2019; Johansen 2020). The toolbox enables the detection, monitoring, and quantification of HAB indicators (chlorophyll-a, phycocyanin, and turbidity) using Sentinel-2 satellite imagery. Four tools are available: (1) automating the download of Sentinel-2 Level-2A imagery, (2) creating stacked image with options for cloud and non-water features masks, (3) applying water quality algorithms to generate relative estimations of one to three water quality parameters (chlorophyll-a, phycocyanin, and turbidity), and (4) creating linear regression graphs and statistics comparing in situ data (from field-based water sampling) to relative estimation data. This document serves as a user’s guide for the waterquality for ArcGIS Pro toolbox and includes instructions on toolbox installation and descriptions of each tool’s inputs, outputs, and troubleshooting guidance.

Research objectives : Identify genetic potential and community structure of soil and rhizosphere microbial community structure as affected by treated wastewater (TWW) irrigation. This objective was achieved through the examination soil and rhizosphere microbial communities of plants irrigated with fresh water (FW) and TWW. Genomic DNA extracted from soil and rhizosphere samples (Minz laboratory) was processed for DNA-based shotgun metagenome sequencing (Green laboratory). High-throughput bioinformatics was performed to compare both taxonomic and functional gene (and pathway) differences between sample types (treatment and location). Identify metabolic pathways induced or repressed by TWW irrigation. To accomplish this objective, shotgun metatranscriptome (RNA-based) sequencing was performed. Expressed genes and pathways were compared to identify significantly differentially expressed features between rhizosphere communities of plants irrigated with FW and TWW. Identify microbial gene functions and pathways affected by TWW irrigation*. To accomplish this objective, we will perform a metaproteome comparison between rhizosphere communities of plants irrigated with FW and TWW and selected soil microbial activities. Integration and evaluation of microbial community function in relation to its structure and genetic potential, and to infer the in situ physiology and function of microbial communities in soil and rhizospere under FW and TWW irrigation regimes. This objective is ongoing due to the need for extensive bioinformatics analysis. As a result of the capabilities of the new PI, we have also been characterizing the transcriptome of the plant roots as affected by the TWW irrigation and comparing the function of the plants to that of the microbiome. *This original objective was not achieved in the course of this study due to technical issues, especially the need to replace the American PIs during the project. However, the fact we were able to analyze more than one plant system as a result of the abilities of the new American PI strengthened the power of the conclusions derived from studies for the 1ˢᵗ and 2ⁿᵈ objectives. Background: As the world population grows, more urban waste is discharged to the environment, and fresh water sources are being polluted. Developing and industrial countries are increasing the use of wastewater and treated wastewater (TWW) for agriculture practice, thus turning the waste product into a valuable resource. Wastewater supplies a year- round reliable source of nutrient-rich water. Despite continuing enhancements in TWW quality, TWW irrigation can still result in unexplained and undesirable effects on crops. In part, these undesirable effects may be attributed to, among other factors, to the effects of TWW on the plant microbiome. Previous studies, including our own, have presented the TWW effect on soil microbial activity and community composition. To the best of our knowledge, however, no comprehensive study yet has been conducted on the microbial population associated BARD Report - Project 4662 Page 2 of 16 BARD Report - Project 4662 Page 3 of 16 with plant roots irrigated with TWW – a critical information gap. In this work, we characterize the effect of TWW irrigation on root-associated microbial community structure and function by using the most innovative tools available in analyzing bacterial community- a combination of microbial marker gene amplicon sequencing, microbial shotunmetagenomics (DNA-based total community and gene content characterization), microbial metatranscriptomics (RNA-based total community and gene content characterization), and plant host transcriptome response. At the core of this research, a mesocosm experiment was conducted to study and characterize the effect of TWW irrigation on tomato and lettuce plants. A focus of this study was on the plant roots, their associated microbial communities, and on the functional activities of plant root-associated microbial communities. We have found that TWW irrigation changes both the soil and root microbial community composition, and that the shift in the plant root microbiome associated with different irrigation was as significant as the changes caused by the plant host or soil type. The change in microbial community structure was accompanied by changes in the microbial community-wide functional potential (i.e., gene content of the entire microbial community, as determined through shotgun metagenome sequencing). The relative abundance of many genes was significantly different in TWW irrigated root microbiome relative to FW-irrigated root microbial communities. For example, the relative abundance of genes encoding for transporters increased in TWW-irrigated roots increased relative to FW-irrigated roots. Similarly, the relative abundance of genes linked to potassium efflux, respiratory systems and nitrogen metabolism were elevated in TWW irrigated roots when compared to FW-irrigated roots. The increased relative abundance of denitrifying genes in TWW systems relative FW systems, suggests that TWW-irrigated roots are more anaerobic compare to FW irrigated root. These gene functional data are consistent with geochemical measurements made from these systems. Specifically, the TWW irrigated soils had higher pH, total organic compound (TOC), sodium, potassium and electric conductivity values in comparison to FW soils. Thus, the root microbiome genetic functional potential can be correlated with pH, TOC and EC values and these factors must take part in the shaping the root microbiome. The expressed functions, as found by the metatranscriptome analysis, revealed many genes that increase in TWW-irrigated plant root microbial population relative to those in the FW-irrigated plants. The most substantial (and significant) were sodium-proton antiporters and Na(+)-translocatingNADH-quinoneoxidoreductase (NQR). The latter protein uses the cell respiratory machinery to harness redox force and convert the energy for efflux of sodium. As the roots and their microbiomes are exposed to the same environmental conditions, it was previously hypothesized that understanding the soil and rhizospheremicrobiome response will shed light on natural processes in these niches. This study demonstrate how newly available tools can better define complex processes and their downstream consequences, such as irrigation with water from different qualities, and to identify primary cues sensed by the plant host irrigated with TWW. From an agricultural perspective, many common practices are complicated processes with many ‘moving parts’, and are hard to characterize and predict. Multiple edaphic and microbial factors are involved, and these can react to many environmental cues. These complex systems are in turn affected by plant growth and exudation, and associated features such as irrigation, fertilization and use of pesticides. However, the combination of shotgun metagenomics, microbial shotgun metatranscriptomics, plant transcriptomics, and physical measurement of soil characteristics provides a mechanism for integrating data from highly complex agricultural systems to eventually provide for plant physiological response prediction and monitoring.
