The Batinah Coastal plain, located between the Hajar mountains and the sea, from Muscat to the UAE border, is a favorable region for groundwater occurrence in Oman and the main source of fresh water in this coastal area. The coastal parts of the Batinah plain, particularly Barka and Suwaiq, have suffered from groundwater deterioration over the past 20 years. This paper reviews the monitoring activities of groundwater electrical conductivity in the Batinah coastal plain between Seeb and Suwaiq over the period 1984 to 2005, an area of approximately 394 km2. GIS and Auto-Cad techniques were applied to illustrate different salinity zones as the wells coordinates and their field EC were digitized on maps with contours. Zones of salinity ranges are identified and their areas were computed and compared to the total catchment area of each wadi. All samples were collected from the same upper gravel layer, ranging in depth 20-100 meters. There has been a substantial deterioration in water quality as indicated by a 7% reduction in areas of water suitable for agriculture use (2.000 – 6.000 μS/cm), reflecting a loss of 2,714 hectares of irrigated land. Also, a saline interface is reported 12 km inland at Wadi al Taww, Barka area, an indication of aquifer over-exploitation. It is therefore critical that monitoring of water quality and quantity is continued. It is recommended to improve implementation of the standard water resources management solutions to coastal aquifer saline contamination. Cooperation of different organizations and water users is essential to conserve these precious water resources.

Abstract. Water resources in Poland continue to be under stress despite systematic efforts to safeguard ground and surface water quality and quantity. Groundwater protection from nitrate pollution of human origin requires the development of sewerage systems. Such investments are often financed from public funds that must be formally appraised. The appraisal should be done by a comparison of benefits and costs of investment measures – not only financial but also environmental and social. A significant challenge is the monetization of the effects on the environment. In this paper we use non-market valuation to examine residents' preferences and estimate their willingness to pay for improving drinking water quality. This paper also contributes to the narrow literature on valuation of benefits of measures for groundwater quality improvement by presenting an application of the choice experiment method in the Czestochowa Region of Poland. To the best of our knowledge this is the first study estimating the value of benefits of the groundwater quality improvement in Poland.

The use of sustainable drainage systems (SuDS) or best management practice is becoming increasingly common. However, rather than adopting the preferred ‘treatment train’ implementation, many developments opt for end-of-pipe control ponds. This paper discusses the use of SuDS in series to form treatment trains and compares their potential performance and effectiveness with end-of-pipe solutions. Land-use, site and catchment characteristics have been used alongside up-to-date guidance, Infoworks CS and MUSIC to determine whole-life-costs, land-take, water quality and quantity for different SuDS combinations. The results presented show that the use of a treatment train allows approaches differing from the traditional use of single SuDS, either source or ‘end-of-pipe’, to be proposed to treat and attenuate runoff. The outcome is a more flexible solution where the footprint allocated to SuDS, costs and water quality can be managed differently to fully meet stakeholder objectives.

Wetlands are a critical resource, essential not only to water quality and quantity, but also to human sustenance and to the thriving ecosystems. Human and ecosystem dependence on wetlands is not well recognised in governmental oversight and community attitudes. As such, markets undervalue them and businesses and industry consider them disposable. Given that the market economy controls the “new normal”, it has not been uncommon for States, when formulating policies to exploit wetland resources for gain, thereby undermining their future and sustainability. India has made some attempts, both nationally and internationally to resolve these matters. This paper is an attempt to showcase one such common property resource, i.e. wetlands in the city of Bangalore, which are under tremendous stress from capitalism.
