This paper articulates the complexities of adaptively managing Delaware River water resources to meet shifting priorities of drinking water supply, drought mitigation and flood mitigation, as well as conflicting stakeholder interests. In particular, the paper examines the short-term and long-term programs that comprise the Delaware River Basin Commission's (DRBC) and the 1954 US Supreme Court Decree parties' successful adaptive management approach that seeks to balance the growing list of demands for water resources management, including drinking water supply, drought management, flood control and cold water fisheries protection. Review of the DRBC's adaptive governance approach reveals the critical complexities of designing experimental, yet science-driven management approaches and effectively engaging various sets of stakeholders in the associated decision-making processes.

Abstract. Rajasthan, the largest State in India, has one of the most critical water statuses. Rajasthan, with more than 10.4 % of the country’s geographical area, supports more than 5.5 % of the human population and 18.70 % of the livestock, but only has 1.16 % of the total surface water available in the country. More than 60 % of the state is a part of the Great Thar Desert, and of the total 142 desert blocks in the country, 85 blocks are in the state of Rajasthan. The per capita annual water availability in the state is about 780 m3, compared with the minimum requirement of 1000 m3. It is feared that the availability would fall below 450 m3 by the year 2050. Thus, increasing population coupled with erratic rainfall further aggravates the water crisis. It is possible to harvest and augment water resources through the construction of small water harvesting structures called johads and the implementation of local water governance. This has been amply demonstrated by the successful experience of local communities in Alwar District in Rajasthan. Since 1985, 8600 johads have been built in 1086 villages. This has resulted in the rise in water levels in the shallow aquifer, increase in the area under single and double crops, increase in forest cover and drinking water supply security. The water collected in a johad during the monsoon penetrates into the sub-soil. This recharges the groundwater and improves the soil moisture in vast areas. The water in the johad can be used directly for irrigation, drinking water by animals, and other domestic purposes. The other advantage of this structure is that it checks soil erosion, mitigates floods, and ensures water availability in wells or boreholes used for drinking water supply, even for several successive drought years. Also, during the dry season when the water gradually recedes in the johad, the land inside the johad itself becomes available for cultivation.

The contamination of the world’s water supply due to various contaminants has caused the clean water supply to shrink around the globe. The problem is not only an issue with developing nations; in fact, many developed countries are facing the same turmoil. With the globalization, industrialization and weak enforcement of environmental regulations, waste water is discharged into clean water resources whereby contaminating the water. Out of the long list of contaminants many heavy metals find their way into the clean drinking water supply. The heavy metals arsenic (As), lead (Pb), and mercury (Hg) as well as many others are also discharged into water resources. There are numerous methods for removal of these heavy metals from water including filtration, chemical precipitation, ion exchange, adsorption, electro deposition as well as others but most are expensive and or not completely satisfactory. Arsenic and its compounds are often used as pesticides, herbicides, insecticides and various alloys and often find their way into the drinking water supply through various industrial sources. A cost-effective remediation of arsenic in water using readily available material is urgently needed. An ashed waste material consisting primarily of Azadirachta indica (Neem leaves) and Mangifera indica (Mango leaves) has been found effective in removing both arsenic (III) and (V) from water. The utilization of this ashed material achieves the concept of using waste material from one source, used by another and therefore benefiting both. The adsorbent is very effective at pH =7 and ion exchange appears to be the major adsorption mechanisms for binding the metal ions to the plant ash material. The material shows sufficient operation capacity to indicate the possibility of its use in remote rural areas as well as in an urban water treatment facility.

The Kota Makassar water utility serving (<em>Perusahaan Daerah Air Minum</em> - PDAM) faces a significant problem in managing water resources for their drinking water supply. The problems comprise raw water supply, the vulnerability of water quality, infrastructures, costs, and climate change uncertainty. The availability of clean water is one of the problems in the field of national defense. Because water is the main source of life in all sectors, be it agriculture or livestock. This study is aimed at assisting officials in making an adaptive and resilient decision. It involves inter-and cross-disciplinary studies within Robust Decision-Making (RDM) in water resources management planning for drinking water supply and disaster mitigation in Makassar. This research applies a qualitative approach in data analysis; reviewing strategies used by the utility management to anticipate all uncertainty, long-term strategies feasibility from simulation models, analyzing potential vulnerability scenarios, and the trade-off for an adaptive and robust decision in water resources management planning for drinking water supply in Makassar through RDM. The novelty lies in the raw water management policy that is more adaptive toward potential vulnerability and presents a variety of raw water supply alternatives in the long term. Reviews against the document of drinking water Master Plan found that the absence of harmony along with a high level of anticipation towards the threat of climate change along with their impact, as well as the threat of the raw water supply limitations due to the exogenous problems beyond the reach of human beings capacity, will result in global and long-term impact.

Background and Objectives: Legionella is one of the most important water-related pathogens. Inside the water supply systems and the biofilms, Legionella interact with other bacteria and free-living amoeba (FLA). Several amoebas may serve as hosts for bacteria in aquatic systems. This study aimed to investigate the co-occurrence of Legionella spp. and FLA in drinking water supply systems. Materials and Methods: A total of 268 water samples were collected from apartment buildings, hotels, and public buildings. Detection of Legionella spp. was performed in accordance with ISO 11731:2017 standard. Three different polymerase chain reaction (PCR) protocols were used to identify FLA. Results: Occurrence of Legionella varied from an average of 12.5% in cold water samples with the most frequent occurrence observed in hot water, in areas receiving untreated groundwater, where 54.0% of the samples were Legionella positive. The occurrence of FLA was significantly higher. On average, 77.2% of samples contained at least one genus of FLA and, depending on the type of sample, the occurrence of FLA could reach 95%. In the samples collected during the study, Legionella was always isolated along with FLA, no samples containing Legionella in the absence of FLA were observed. Conclusions: The data obtained in our study can help to focus on the extensive distribution, close interaction, and long-term persistence of Legionella and FLA. Lack of Legionella risk management plans and control procedures may promote further spread of Legionella in water supply systems. In addition, the high incidence of Legionella-related FLA suggests that traditional monitoring methods may not be sufficient for Legionella control.

The Impact

Riverbank filtration (RBF) is a well proven natural treatment, which in many countries is part of a multi-barrier concept in drinking water supply. The induced infiltration of river water into the aquifer produces a significant improvement in river water quality. Riverbank filtration wells are characterized by a high capacity. Based on data from recent years, an integrated approach to assessing the impact of climate change on safe drinking water production by RBF is demonstrated in the Lower Rhine Valley, Germany. Influencing factors on quantitative as well as qualitative aspects were identified. During low river water periods, the capacity of the RBF-wells decreases. In addition the lower discharge within the river is accompanied by a increased concentration of several chemical compounds. Together with higher water temperatures which influence the hydrogeochemical processes during RBF, the changing raw water composition has to be considered for the subsequent technical treatment step. However, our investigations reveal that despite the impact of climate change on RBF, the multi-protective barrier concept, including both natural and technical purification, has proven a reliable method for drinking water production. The sanitation of the Rhine over the last decades was an important step to make RBF more resilient to climate change.
