The Impact

We examine the impact of poor water quality on avoidance behavior by estimating the change in bottled water purchases in response to drinking water violations. Using data from a national grocery chain matched with water quality violations, we find an increase in bottled water sales of 22 percent from violations due to microorganisms and 17 percent from violations due to elements and chemicals. Back-of-the envelope calculations yield costs of avoidance behavior at roughly $60 million for all nationwide violations in 2005, which likely reflects a significant understatement of the total willingness to pay to eliminate violations.

Baseline Information

Water resources in the Chia lagoon in Malawi experience a possible threat to sustainability. Communities are seeking alternatives to improve water quality in the lagoon. This study quantified the communities’ willingness-to-pay (WTP) and their influencing factors while using contingent valuation (CV) techniques. A wide range of data collection procedures, including focus group discussions, key informant interviews, field observation, and CV survey, were employed. A sample of 300 households was randomly selected. The CV results showed that 57.4% of the households were willing to pay. The monthly individual aggregate WTP amount ranged from MK696.83 (US$0.95) to MK81697 (US$111.38), and on average MK7870.45 (US$10.73), generating aggregate annual values ranging from MK6, 689,568 (US$9126.29) to MK784, 294,080 (US$1,069,978), and on average MK75,556,320 (US$103,078) (ceteris paribus). Logistic regression model demonstrated a significant (p < 0.01 or p < 0.05) relationship between demographic (gender, age, literacy level), social-economic (land ownership, main agriculture water source, and income), and institutional (civic education and social network, extension, institutional trust, household socio trust) factors and WTP. The findings from this study provide significant clues for further research and baseline information for local government and communities in the development of more effective and holistic approaches for improving water quality in natural ecosystems.

Abstract In order to integrate ecosystem services (ES) in designing agri-environmental policy, we investigated both the demand for, and supply of, ES from agricultural environments in Finland. Using the discrete choice experiment method, we measured citizens’ willingness to pay (WTP) for four different ES and analysed farmers’ compensation request (willingness to accept [WTA]) for producing these services. Biodiversity and water quality gathered the highest WTA of farmers, but also the highest WTP of citizens. Overall, the average WTA exceeded the WTP for almost all attributes and levels, but 20–27 per cent of farmers were willing to produce the ES with the compensation lower than citizens’ WTP.

Preliminary Study

A preliminary study on the water quality of a reservoir, affected by agriculture, in the east of Thailand was conducted during 1996-1997. Monitoring water quality of a reservoir is important because the sloping lands surrounding the reservoirs are mainly utilized for cultivating cash crops (pineapple, cassava, etc). A lot of fertilizers and agrochemicals were applied to soil and crops which can polluted the water . The results from the preliminary studied will be applied for the monitoring of the water quality in other reservoirs in the 16 pilot areas.

Quality Health

The state of Penang has been known to be offering the lowest water tariff rate for its users in Malaysia. The most recent water services reform exercise in Malaysia saw a suggestion made for the abolishment of water subsidies by the federal government and for full cost recovery (FCR) approach to be applied. This means that the operating cost will be transferred to consumers instead. This study reports a descriptive pilot study results that explored Penang user’s responses to various issues pertaining to their perception of water quality, health risk concern and willingness to pay for increased water tariff. The findings show that users were not that happy with water quality only in terms of taste, suspended solids that should not have come out from the tap but sometimes they do, and chlorine content; however, not for its odor or color. As for health risk concern, although majority believe that their tap water adhered to the drinking standard set by World Health Organization (WHO), still many perceived that their tap water is associated with health risk and unsafe for drinking, which saw many opted to buy bottled water for their drinking consumption. As for willingness to pay, majority think that the tariff should not be increased at all, particularly at the current water quality provided to users. Gender and monthly income as part of demographic factor play important roles in enhancing the study’s outcome.  The findings provide preliminary insight to how water users may act towards a possible water tariff increase in the state.

<p>It is well recognized that the classical biological and chemical markers of environmental pollution do not necessarily indicate the presence or absence of emerging threats to public health, such as waterborne viruses and genotoxicants. The purpose of this preliminary study was to evaluate the presence of material of enteroviruses (EV), rotavirus (RV) and adenovirus (AdV) and genotoxicity in water samples from points of routine monitoring of water quality in the main course of the Sinos River. The points are classified into different levels of pollution in accordance to the Brazilian federal regulations. Viral genomes from EV, AdV were detected in two of the 4 collection points regardless of the level of urbanisation of the surrounding areas. In contrast, genotoxicity was not observed in piava (<italic>Leporinus obtusidens</italic>) fingerlings cultivated on these same water samples. Results were compared with classical physical, chemical and microbiological parameters. There was no clear evidence of association between any of the classical markers and the presence of viral genomes in the water samples tested.</p>

Bendungan Telaga Tunjung terletak di Desa Timpag, Kecamatan Kerambitan, Kabupaten Tabanan, Provinsi Bali. Dalam perkembangannya, wilayah sekitar bendungan dimanfaatkan untuk kegiatan pertanian, industri serta pemukiman yang memungkinkan terdapatnya masukan bahan pencemar seperti logam berat. Berdasarkan hal tersebut, perlu dilakukan penelitian mengenai kualitas perairan ditinjau dari kandungan logam berat, mengingat fungsi bendungan yang dimanfaatkan untuk masyarakat. Penelitian ini bertujuan untuk mengidentifikasi konsentrasi kandungan logam berat Timbal (Pb) dan Kadmium (Cd) pada kolom air dan ikan nila (Oreochromis niloticus, Linn.) di Bendungan Telaga Tunjung, yang dilakukan pada bulan Februari 2016. Metode yang digunakan adalah metode purposive sampling, dengan teknik pengambilan sampel air dilakukan secara komposit pada 5 stasiun berdasarkan perwakilan perairan bendungan. Pengambilan sampel air dilakukan sebanyak 3 kali setiap 2 minggu, dan pengambilan sampel ikan dilakukan secara acak sebanyak 1 ekor setiap 2 minggu. Kandungan logam berat dianalisis menggunakan alat Plasma Atomic Emission Spectrometer ICPE-9000. Kosentrasi logam berat Timbal (Pb) di badan air yang diperoleh berkisar 0 – 0,009 mg/l, dan Kadmium (Cd) berkisar 0,135 – 0,310 mg/l. Pada ikan nila, konsentrasi timbal tidak dapat terdeteksi, dan konsentrasi kadmium yang di dapat berkisar 0,330 – 0,728 mg/kg. Hasil tersebut menunjukkan bahwa perairan di Bendungan Telaga Tunjung telah tercemar oleh logam berat Kadmium (Cd), karena telah melebihi ambang baku yang ditetapkan Peraturan Gubernur Bali Nomor 8 Tahun 2007 tentang Baku Mutu Lingkungan Hidup dan Kriteria Baku Kerusakan Lingkungan Hidup Kelas II yaitu sebesar 0,03 mg/l, dan melebihi ambang baku yang ditetapkan SNI (Standar Nasional Indonesia) 7387:2009 sebesar 0,1 mg/kg untuk ikan dan hasil olahannya.
