This project is being funded through the Focus Area Program, which enables WRF to solve broadly relevant subscriber issues and challenges with a targeted, sustained research effort. The program is developed around research Focus Areas: a topic area that is of high interest and priority to WRF subscribers because of a challenge or opportunity that is present, emerging, or anticipated, and for which research will help subscribers manage and address the challenge or optimize the opportunity. A focus area includes a discrete challenge or opportunity statement, measurable objectives, and one or more projects that will lead to applied solutions and benefits for WRF subscribers within a specified, relevant time frame. FOCUS AREA RFP This project is funded under the Focus Area titled, Waterborne Pathogens in Distribution and Plumbing Systems and is intended to support the Focus Area objective(s): To understand the factors governing the proliferation of waterborne pathogens. Method(s) for Detecting and Differentiating Opportunistic Premise Plumbing Pathogens (OPPPs) to Determine Efficacy of Control and Treatment Technologies (RFP #4721) Project Objective The objective of this project is to develop and/or optimize method(s) for detecting and differentiating multiple opportunistic premise plumbing pathogens and to demonstrate method applicability, suitability, and effective use following OPPP treatment and control options. Budget Proposals may request WRF funds in the range of $225,000 - $250,000. WRF funds requested and total project value will be a criterion considered in the proposal selection process. Background The presence of opportunistic premise plumbing pathogens (OPPPs) (e.g., Legionella pneumophila, nontuberculous mycobacteria, Acanthamoeba, Naegleria fowleri, Pseudomonas aeruginosa, to name a few) in drinking water distribution and plumbing systems has continued to grow in significance as a public health concern. However, the ability to provide reliable, sensitive and quantitative detection and differentiation of live and infectious pathogens remains a significant challenge for OPPPs. Currently, there is a lack of standardized methodologies or protocols for detecting and differentiating the variety of OPPPs potentially in potable water. The primary advantage of culture-based methods for detection of OPPPs remains their ability to confirm the presence of live pathogens. However, published data suggest that certain bacterial pathogens, such as Pseudomonas and Legionella, can under certain environmental conditions (e.g., presence of specific metal ions), survive in a viable but non-culturable (VBNC) state. There is also evidence that some strains of specific OPPPs present a larger risk to public health, especially to susceptible populations, but no methodologies to discriminate between pathogenicity currently exist. Free-living (trophozoic) protozoan organisms may play a critical role in biofilms as both primary pathogens and/or hosts for certain bacterial pathogens. They can also survive disinfection in a cystic state. Current detection methods provide limited ability to differentiate trophozoites from cysts, and even less ability to determine the infectivity of cysts.
Some molecular-based methodologies have been designed to distinguish non-viable cells from those in a dormant state. But these molecular methods have not been rigorously tested. While, molecular-based methods provide some distinct advantages including specificity and sensitivity, and the potential to produce high-throughput results, they are limited by the lack of both standardization and studies which directly compare their performance to that of other detection methods. Detailed information on OPPPs detection methodologies can be found in WRF report 4379 [1]. There is a need to develop reliable, sensitive, and quantitative method(s) for detecting and differentiating multiple opportunistic premise plumbing pathogens in order to demonstrate the effectiveness of OPPP treatment and control options. Several disinfection strategies are used for the control of a wide range of pathogens in drinking water distribution systems, including premise plumbing. Some studies have shown that the use of chloramine seems to reduce the frequency of L. pneumophila, but other studies have shown that this leads to an increase in the numbers of mycobacteria. Baron et al. (2014) observed a shift in the microbial ecology of a hospital s hot water system, following chloramination, using the Illumina 16S rrna sequencing population analysis [2]. However, the effectiveness of current control strategies is still not well documented because the methods for OPPPs have not been fully developed or validated. The deliverables of this project include the development of OPPP detection method(s) that are applicable and suitable tools for use in determining control and treatment effectiveness. In addition, the research team will evaluate the methods performance using at least one control option. Research Approach With a focus on known opportunistic pathogens in drinking water systems, select at least 3 OPPPs, and provide compelling reasons to support the selection. Complete a literature review to support the research direction. Propose the most appropriate fit-for-purpose method(s) for detecting and differentiating the opportunistic premise plumbing pathogens selected above. Demonstrate performance in a range of drinking water and premise plumbing (bulk water/biofilm) matrices. Because OPPPs can exist in several forms in nature (e.g., cyst, trophozoite, vegetative, viable but non-culturable, etc.), the proposed method(s) need to quantitatively differentiate between actively growing, dormant, and/or dead cells, etc. Appropriate positive controls and internal controls must be included. The developed method(s) should be evaluated for determining the effectiveness of OPPP treatments and control options. To do so, choose at least one control method/treatment/operation (e.g., chlorination, chloramination, heat treatment, copper-silver ionization UV, plumbing operation, etc.) to demonstrate the applicability of the detection method in documenting the effectiveness of the control option in either a bench or pilot test format. Prepare a report detailing the methodology, sensitivity, specificity, speed, accuracy, cost, and training required for the developed method(s). Consider holding a workshop or webinar to disseminate the methodology and provide training to water utility professionals.
Prepare a publishable report demonstrating the effectiveness of at least one control option, using the method(s) developed for OPPPs. References 1. A. Pruden, M. Edwards, and J.
