Two cases of taste and odor episodes in raw and groundwater in the Barcelona (NE Spain) metropolitan area are described. The first was caused by creosote, a distill of coal tar, dumped into river water by two wood-preserving factories. The second taste and odor episode was caused by the presence of a potent odorous compound, the 2-ethyl-5,5-dimethyl-1,3-dioxane, in different groundwater samples. This compound is a by-product present in wastes from resin manufacturing plants that use neopentyl glycol as a raw material for acid-catalysed condensations.

The Impact

Good management of water resources is a requirement for an area that has a high population development. Sentul City, which is an independent city in Bogor Regency which has a high population, is in an area that lacks water, because of this Sentul City requires infrastructure and policies that are able to ensure the availability of water for its residents. One of the paradigms of water management in urban areas is a water sensitive city. One of the steps in this paradigm is wastewater management and rainwater harvesting. The dynamic system modelling method is used to predict the impact of implementing several policies that will be taken to manage water resources. The objectives of this study are to build dynamic models to predict water supply and demand and to analyze policies for wastewater management and rainwater harvesting. Sentul City water demand is estimated will reach 122 105 000 m3 and a water crisis will occur in 2027. The wastewater recycle policy can inhibit the water crisis until 2030 and the negative water balance will last until 2040. Combining wastewater recycle and rainwater harvesting can increase water availability by 240% and prevent a water crisis.

Meteorological Droughts

The Monterrey Metropolitan Area (MMA) is located in northeastern Mexico in a semi-arid region. As in other areas of the world, prolonged and severe meteorological droughts are recurrent. Meteorological droughts affect the level of dam reservoirs, rivers, and groundwater (aquifers) in the region to the extent they become hydrological droughts which in turn may contribute to socioeconomic droughts. The recent dry event (2011–2013) in northern Mexico severely affected various socioeconomic sectors and may serve as an example of future climatic and hydrologic conditions in this region. Meteorological droughts in northeastern Mexico, mostly induced by anomalously intense subsidence, frequently result in hydrological droughts and intense pressure in the water resources services of the Monterrey Metropolitan Area (MMA), one of the largest cities in Mexico. Landfalling tropical cyclones entering northeastern Mexico historically have alleviated water crises during prolonged droughts. In 2013, the rains from tropical cyclone Ingrid helped to recover water levels in the system of dam reservoirs that provides water to the MMA. However, water management is only one part of a complex socioeconomic system that must respond to the growing demands for water in a region where aquifers are already overexploited. Trends in the atmospheric circulation indicate that droughts in the region may become more severe in the coming decades. Improved water management programs and protocols should be considered in addition to closer reviews of the hydraulic infrastructure. Water transfers from one region to another should be carefully planned because solving a problem in one place may adversely affect another. The use of climate information may be critical to avoidance of water conflicts in the future.

<p>Water supply in large cities has challenged governments and water authorities because of the complexity involved in meeting water demands. The traditional challenges stem from the seasonality of precipitation and population growth. Although water resources management strategies assume potential scenarios for water demand growth to design water infrastructure, unexpected changes in the hydrological cycle may cause shocks to urban water supply systems and generate unanticipated patterns of consumption, such as occurred during the water crisis experienced by the São Paulo Metropolitan Area (SPMA) from 2014 to 2016. This work explores the coevolution of the coupled human-water system variables associated with the water supply system within the SPMA, from the late twentieth century to the present, to explain how water demand has influenced water availability, and vice-versa, in particular for the Cantareira Reservoir System. The challenges facing the human-water system in the region are of critical importance, given that it supplies water to more than 9 million people, and it supports economic activities that represent 12% of Brazil’s Gross Domestic Product. The analysis reveals that hydrological shifts are responsible for major structural transformations and they also have led to changes in domestic consumption. We conclude that modelling the interactions and feedbacks between water availability and consumption can provide more realistic storylines to implement strategies to address water scarcity than merely considering long-term demand scenarios, as it is normally done. In addition, policies implemented to promote water savings can have different responses at sub-regional scales and this can be explored also in the context of long-term scenarios.</p>

Abstract Brazil's Southeast region has been facing water supply challenges, especially concerning the metropolitan region of São Paulo, since 2014. We adressed the water crisis from the disaster's point of view, considering that one of the guiding features to characterize a disaster is the amount of affected people and the losses associated. In the situation under review, there are people directly affected, because of intermittent house water supply, and indirectly affected by the increase of prices for goods, since their production and manufacturing depend on the availability of water. We presented each of the stages of a disaster risk management: prevention, mitigation, preparedness, response and recovery. The risk of water scarcity in São Paulo is only one aspect of the discussion involving the effectiveness of management processes and the need for investments in the area, especially in reducing wasteful distribution.
