This chapter follows Native and Euro-American communities in eastern Massachusetts through the twentieth and twenty-first centuries, examining a series of commemorations and counterprotests that unfolded in urbanizing areas and related sites. It analyzes how Bostonians’ conceptions of the city and modernity tended to exclude Native peoples from both, instead relegating them to the past—despite the presence of numerous “Urban Indians” in the growing metropolis, who were seeking employment and social opportunities. It considers a series of pageants and historical markers erected across the Commonwealth, as well as Native pushback against dominant Euro-American narratives about history, such as a 1970 gathering in Patuxet/Plymouth, Massachusetts that foregrounded Indigenous perspectives and inaugurated an annual National Day of Mourning. The chapter also details how tribal communities challenged plans to build a sewage treatment plant on Deer Island, on grounds considered intensely sensitive for their ties to the incarcerations of King Philip’s War. Finally, it illuminates a recent series of memorial journeys along the Charles River and Boston Harbor Islands in which mishoonash (Native dugout canoes) have played important roles in reconnecting Native descendants to the landscapes of ancestors, as well as providing avenues for Indigenous solidarities into the future.

Abstract A comparison of costs of implementing an advanced wastewater treatment system for a cadmium plating plant, versus the sludge disposal costs of the sewage treatment plant to which the plating plant is discharging its effluent, is described. An economic analysis spreadsheet approach using Lotus 1-2-3 is employed. A case study application demonstrates for overall society net benefit that it is cost-effective to initiate pretreatment at electroplating facilities which allows a municipal facility to dispose of its sludge on agricultural land rather than be required for landfilling. Sensitivity analyses to market interest rate, sludge production, sludge disposal fees and drag-out rates are explored.

Land Cost

Employing stabilization pond systems to treat wastewater has the advantages of being economical of energy, easy to operate, and low in operation costs. However, stabilization pond systems have the problem of occupying large areas of land. Therefore, only after an overall technical economic analysis is made can an assessment be made of whether it is feasible to employ a stabilization pond systems to treat wastewater. During the period of the Seventh Five-year Plan of China, the “Study on the Technology of Stabilization Ponds” was set as one of the national scientific and technological key items. Seven experimental bases were established ranging from the north down to the south of China. With the great numbers of operational data obtained from both these bases and the existing stabilization pond systems, an analysis of the composition of the capital outlay in the stabilization pond system construction was made. The analysis shows that the land purchase cost accounts for approximately 60% of the capital outlay in construction and is the most important influencing factor. A comparison between the various costs of stabilization pond systems and those of conventional sewage treatment plant was made. Thereupon two new parameters were put forward: “equal capital land cost” and “upper limit of feasible land cost”. At the same time, a nationwide isogram of these two parameters was plotted. This isogram may be useful for preliminary design and planning purposes, and may be helpful to the users to assess comparatively easily whether its feasible to employ stabilization pond system.

The influence of the discharged treated wastewater on the ecology of the Kafirnigan River is considered. The data on the current state of sewage treatment facilities in the city of Dushanbe are given and an assessment of the environmental efficiency of these treatment facilities is given. Preliminary calculations of costs for the construction of a new sewage treatment plant in Dushanbe have been made. The article is devoted to the current problem of cleaning storm sewers. It should be noted that storm water drainage, like wastewater, has a negative impact on the environment. Before the wastewater is disposed of, it is necessary to treat it in a special way, subjecting it to treatment of varying degrees and depths.

The City

Raigarh is a rapidly growing industrial city situated in the state of Chhattisgarh, spread over an area of 46.54 km2. It is characterized by its rising population, mounting urbanization, and motorization. The population, of the city, is 1,66,460 as per the census year 2011 and it will be increased by 2,90,988 till the year 2035. There will be an increase not only economically but also there will be a rise in population along with infrastructure works so there is a basic need at the construction of a sewage treatment plant with a view of sufficient capacity to treat the sewage. The objectives of this study are to review and evaluate sewage treatment technologies and propose a sewage treatment plant to improve Kelo River water.

Term Monitoring

The present survey was carried out in the framework of MEDPOL Phase III (2004 – 2006), aiming to provide recent information for the long-term monitoring of pollution trends in selected susceptible marine environments along the Mediterranean coastline. Information was collected from a network of four stations spaced out along the eastern coast of the Island of Lesvos, Greece, including a high risk station near the harbour of the city of Mytilini. Pollutants in abiotic components of the marine environment (seawater, sediment) as well as in selected marine organisms (M. barbatus and B. boops) were measured. It was found that there is no evidence of substantial pollution of the marine environment (seawater, sediment and fish) with respect to the pollutants measured. However, it was shown that although the uncontrolled discharge of untreated effluents has been reduced since the beginning of the operation of the Mytilini sewage treatment plant in 2001, sediments near the harbour of the city still carry increased loads of metals of anthropogenic origin. Furthermore, the small quantity of untreated sewerage that still flows out in the harbour of the city seems to affect water quality, since a higher mesotrophic character with eutrophic trends was observed in the area.

River Ganga arises on the southern slopes of the Indian central Himalayan region beginning the Gangotri glacier. The river covers catchment area of 8, 61,404 km2 and its total length in the state Bihar stretch is 475 km. This study was carried out at Patna in the river Ganga at two sampling sites, viz., Digha Ghat (upstream) and Gai Ghat (downstream). The objective of the study was to observe the eminence of water of Ganga at Patna. The results that indicate that the river reaches near the city of Patna (upstream at Digha Ghat) are less polluted with pH 7.75, DO 7.42 mg/l, BOD 2.48 mg/l and COD 15.12 mg/l, while when the river leaves city after travelling 18 km (downstream at Gai Ghat), concentration of all pollutants increases significantly (pH 6.28, DO 6.22 mg/l, BOD 2 mg/l and COD 23 mg/l). The concentration of coliform bacteria (total coliform ranges from 5000 to 6000 MPN/100ml and faecal coliform ranges from 2200 MPN/100ml and 3000 MPN/100ml at both the sites) was recorded at higher level than the upper limit of the permissible level. This increment may be due to domestic and sewage discharge from the city. The municipality of Patna has sewage treatment plant capacity of about 109 MLD but whereas the city generates approximately 250 MLD sewage/township discharge. For the maintenance of pristine quality of water of the river Ganga, the sewage need be treated before discharge

This study summarizes the findings and lessons learned from the start up and operation of a large wastewater treatment plant in warm climate under modified conditions. The treatment works comprise of a newly constructed sewage treatment plant located in the city of Dubai, U.A.E with an ultimate capacity of 300 Ml/d. The plant can be reviewed in three major parts; (i) liquid stream, (ii) sludge stream and (iii) odor control stream all having the latest state of the art technology and related equipments. The challenge in starting up the plant was related to the fact that only 20% of the flow was available in the form of hauled sewage to be hauled from septic tanks located in various parts of the city and also from the nearby industry which was uncontrollable. Furthermore, some parts of the plant were not ready to be commissioned on the day of the planned startup not to mention that effluent irrigation main was not complete to receive the treated sewage effluent (TSE) from the plant. A comprehensive commissioning plan was implemented and followed during the startup which was tailored according to the actual conditions. The plant commissioning was conducted in a phased sequence to cater for the expected and unexpected changes related to the inlet conditions. Commissioning and operation of the plant was carried for over 18 months with success considering the challenging and difficult conditions.
