Pollution Loads

This paper investigated the effectiveness of natural wetlands (Phragmites australis) along Wadi Zomer in reducing the organic and inorganic pollution loads from diverse industrial discharges including occasional emergency discharges from Nablus West Sewage Treatment Plant (NWSTP), Palestine. We monitored physical and chemical parameters at four selective sampling stations (S1-S4) along Wadi Zomer with a length of 5 km downstream of NWSTP to assess the purification capacity of Wadi Zomer treatment wetlands (water, sediment, and vegetation) with Phragmites australis in pollution loads reduction. The results showed that S2 (0+0.5 km) and S3 (0+3.0 km) reflected an increase in pollution loads due to illicit industrial discharge and sewer overflow discharge from NWSTP during emergency conditions. BOD values varied significantly along the sampling sites from 6.64 mg/l (S1) to 437.10 mg/l (S3). The BOD at S1 and S2 in water samples were below the Palestinian Water Standard (PWS) compared to S3 and S4 with 437.1 and 333.9 mg/l, respectively. Water samples from all sites (S1-S4) showed a decreasing tendency in heavy metals concentrations (Fe>Cu>Zn>Cr >Ni) and were below the PWS limits, sediment samples followed the same decrease pattern for Zn, Cr, and Ni content with Wadi Zomer flow course. The concentration of Fe (6687 mg/kg) and Cu (1384.7 mg/kg) were highest in the sediment samples (S1-S4); this might be due to non-point sources of pollution. The research demonstrated that phytoremediation is a sustainable nature-based technology for the restoration of heavily polluted surface water bodies in Palestine.

Abstract The human polyomaviruses JC and BK (JCPyV and BKPyV) are ubiquitous, species-specific viruses that belong to the family Polyomaviridae. These viruses are known to be excreted in human urine, and they are potential indicators of human wastewater contamination. In order to assess the distribution of both JCPyV and BKPyV in urban water samples collected from a sewage treatment plant (STP) and from a canalized water stream of Porto Alegre, Brazil, two nested-PCR assays were optimized and applied to the samples collected. The amplicons obtained were submitted to sequencing, and the sequences were analyzed with sequences of human polyomaviruses previously deposited in GenBank. Twelve out of 30 water samples (40%) were JCPyV positive, whereas six samples (20%) were BKPyV positive. The sequencing results confirmed the presence of JCPyV subtypes 1 and 3, whereas only BKPyV Ia and Ib were found. This study shows for the first time the presence of human polyomaviruses in surface water and in samples collected in a sewage treatment plant in southern Brazil.

Early Survey

Abstract Heavy urbanisation increasingly isolates and exerts pressure on natural wetlands, particularly in rapidly growing tropical developing countries, including West Africa. Constructed wetlands such as sewage treatment plants, may unintendedly offer wildlife protection due to prohibitive access control and limited use, thereby attracting wary and specialised waterbirds, otherwise heavily disturbed in formally protected wetlands with less polluted waterbodies. We present data from a rapid survey on 1-year post-opening colonisation and use of waterbirds in a recently constructed 11 ha restricted-access sewage treatment plant situated in Ghana’s capital, Accra. During November-December 2013 and January 2014, nine daily counts in each month produced an accumulated count of >4200 observations belonging to 26 species of waterbirds, including several important Afro-Palaearctic and intra-African migrants, hereunder ardeids, piscivorous divers, waterfowl and waders. The distributional patterns of waterbirds clearly reflected local foraging opportunities and water quality parameters in the system of 12 inter-connected waste stabilisation ponds. A nearby semi-natural wetland with cleaner waterbodies, but higher levels of human interference, supported half as many waterbirds, predominantly commensal gregarious species. Our data suggests that strict protection from disturbances outweighs possible negative implications attributed to mere pollution of waterbodies supporting various waterbird guilds, thus highlighting the potential importance of non-formally protected sewage treatment plants distributed in functional networks, as a complement to designated wetlands. We contemplate that establishing similar or larger plants jointly will improve sewage treatment and waterbird conservation in urban Ghana, and West Africa in general.

In order to develop a criteria system for assessing the environmental hazards associated with wastewater discharges, a research project was initiated to investigate the suitability of tests commonly used in the assessment of single substances. Toxicity tests with micro-organisms, algae, waterflea and fish, a mutagenicity test and a RPLC-based method were applied to industrial effluents and sewage treatment plant effluents. The biological tests, including the Ames Salmonella test, showed good applicability/sewage treatment plant effluents being a proper reference. The RPLC-analysis on the contrary needs to be further investigated and optimized. Special attention has to be paid to the interpreting of the results from these laboratory tests in relation to possible adverse effects in the receiving surface waters.

Drinking Water Samples

The occurrence of 51 pharmaceuticals and personal care products (PPCPs) and endocrine disrupting compounds (EDCs) in the Detroit River Watershed (DRW) was investigated. Also, the efficiency of local water treatment plants (WTPs) in removing these pollutants was evaluated. Samples were collected from various locations in the DRW, including the discharge of a sewage treatment plant (STP), downstream of the STP on the Detroit River, the intakes of the WTPs, and treated drinking water. Of the 51 target substances analyzed, 12 were not detected in any of the samples, while 14 were detected consistently in all samples from the STP effluent. The concentration of target chemicals was two to four orders of magnitude higher in the STP effluents than at the intakes of the WTPs. In total, 10 substances were detected in at least 10% of the drinking water samples. Two compounds, perfluorooctanoic acid (PFOA) and perfluorooctyl solfonate (PFOS), were found in 90+% of the drinking water samples.

Abstract Microplastics (MPs), generally found in all environment matrices, have become a hot issue in the word. In this study, a typical shallow lake (Baiyangdian) in Northern China was selected, MPs (0.45 μm-5 mm) in different depth of the water and sediment samples were determined. The abundance of MPs in water samples was 1000-20000 items /m3 (9595 items /m3 in average) and 400-2200 items /kg (1023 items /kg in average) in sediment samples. Since the pollution abatement measures implemented, MPs visible to eyes are generally eliminated, the detected MPs in this study are mainly μm sizes with no more than 3-5 items being mm size for each collected sample. The main forms of MPs are fibrous and fragmented with components mainly being polyamide (PA), polyethylene (PE) and polypropylene (PP). MPs in the water at the garbage transfer station can be ranked as surface water < middle water < bottom water and the sediment contained obviously higher MP fragments indicating the history transferring of garbage can be a main cause of plastic deposition in this place. The content of fibrous MPs in surface water was high, and the fragments were found increasing with the depth of water. The southern area contained less MPs compared with the middle and north part of Baiyangdian lake due to the less human activities. The main sources of MPs in this area are the earlier residents' activities, the running of local plastic factories and the effluent from sewage treatment plant.

Abstract:Phosphorus is a major substance that is needed especially for agricultural production or for the industry. At the same time it is an important component of wastewater. At present, the waste management priority is recycling and this requirement is also transferred to wastewater treatment plants. Substances in wastewater can be recovered and utilized. In Europe (in Germany and Austria already legally binding), access to phosphorus-containing sewage treatment is changing. This paper dealt with the issue of phosphorus on the sewage treatment plant in Nitra. There are several industrial areas in Nitra where record major producers in phosphorus production in sewage. The new wastewater treatment plant is built as a mechanicalbiological wastewater treatment plant with simultaneous nitrification and denitrification, sludge regeneration, an anaerobic zone for biological phosphorus removal at the beginning of the process and chemical phosphorus precipitation. The sludge management is anaerobic sludge stabilization with heating and mechanical dewatering of stabilized sludge and gas management. The aim of the work was to document the phosphorus balance in all parts of the wastewater treatment plant - from the inflow of raw water to the outflow of purified water and the production of excess sludge. Balancing quantities in the wastewater treatment plant treatment processes provide information where efficient phosphorus recovery could be possible. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. There are also two outflows - drainage of cleaned water to the recipient - the river Nitra - 9.9 kg Ptot/day and Ptot content in sewage sludge - about 120.3 kg Ptot/day - total 130.2 kg Ptot/day.

Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.
