Abstract
Contamination of natural water through point and non-point sources can degrade the quality of urban waterways risking the health of humans and aquatic animals. While the presence of anthropogenic compounds in various natural water bodies has been well studied, there is not much information in the literature on the simultaneous application of chemical and biological markers for identification of diffuse source contamination. In this work, a fingerprint for detecting untreated sewage in urban waterways is developed by associating a suite of 25 reliable chemical markers and 5 source-specific biomarkers. 12 outfall samples, 32 surface water samples, and two groundwater samples were studied. With few exceptions all target chemical markers were detected in study samples. Sucralose and acesulfame were detected in all water matrices including groundwater, and acetaminophen was detected with the highest median concentration. Human-associated biomarkers, Bacteroidales (BacH) and F-RNA-II coliphages correlated well with several labile chemical markers such as Nicotine, Caffeine, Ibuprofen and Naproxen (0.42–0.75, p < 0.05). They were also moderately to strongly associated with conservative chemical markers Acesulfame, Metformin, and Triclocarban (0.46–0.79, p < 0.05). Human mitochondrial DNA MitoH correlated moderately with labile markers nicotine and salicylic acid as well as with conservative markers Metformin and Triclocarban (0.31–0.47, p < 0.05). This study demonstrated that by associating chemical and biological markers, a robust technique was developed for fingerprinting source-specific untreated waste and fecal contamination in natural water resources.
期刊介绍：
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
