Most water supply programmes in Cambodia have focused on providing access to bacteriologically safe water, an approach which has led to an increasing reliance on ground water, especially in rural areas. However, there have been very few data collected on the chemical quality of the nation's drinking water sources, and few water supply programmes have the capacity to assess chemical quality. The study was designed to address this data gap by conducting a low-cost, rapid assessment of drinking water sources nationwide to determine whether there were any chemicals of concern in Cambodian water supply sources. Results of the assessment confirm that there are several parameters of health and aesthetic concern; dissolved arsenic is the most significant. Elevated arsenic levels (some exceeding 500 μg l-1) were detected in aquifers of moderate depth in several highly populated areas, confirming that further investigation of the occurrence of arsenic contamination in Cambodia is warranted. Other chemicals of health concern include nitrate, nitrite, fluoride and manganese. Additionally, many ground water sources are negatively impacted by parameters of aesthetic concern, such as iron, manganese, hardness and total dissolved solids. Elevated levels of these parameters have caused consumers to reject newly installed water supplies, often in favour of surface water sources that are bacteriologically unsafe.

Abstract Myanmar is an agriculture-based country with 70% of the total population residing in rural areas. Around half of the total population in Myanmar has to consume water from unimproved sources. The prevalence of diarrhea due to contaminated drinking water is high even in urban areas. The urban community may expect the provision of municipal water supply in the near future if the current revolution in the country succeeds. However, the rural areas have lesser or no chance to get quality water because of a lot of other prioritized tasks. Household water treatment is encouraged to be implemented as one of the national water safety plans for rural water supply in Myanmar. This study explored the diarrhea prevention awareness of the rural community using a questionnaire survey. The microbial quality parameters of drinking water sources were also examined. Fecal coliform contamination was detected in all examined drinking water sources. A significant association was found between drinking untreated water and the occurrence of diarrhea. The percentage of people who applied the diarrhea preventive measures was low. Even if they knew how to prevent the disease, very few people applied the measures in reality. Therefore, measures to cause behavioral change should be initiated, together with awareness raising, to promote diarrhea prevention in the community.

Primary Water

Abstract Hill tribe villages are located in mountainous and remote areas. Primary water supply and drinking water sources are mountain water from a small weir on the mountain. Most mountain waters found turbidity higher than 1 NTU, and water quality was unclean to use and drink. This research applied different concentrations of alum doses to observe turbidity reduction. Optimum alum does apply to reduce turbidity for mountain water samples from Hmong, Karen, Lahu, and Lisu for three seasons. The optimum alum dose is between 20 - 40 mg/l in rainy seasons and 10 – 40 mg/l in summer. The cold season was low optimum alum dose at 10 mg/l for all hill tribe villages. Therefore, alum coagulants can be used to treat the mountain water supply and drinking that can implement the main problem of mountain water in hill tribe village.

Langat River

Chemical pollution in the transboundary Langat River in Malaysia is common both from point and non-point sources. Therefore, the water treatment plants (WTPS) at the Langat River Basin have experienced frequent shutdown incidents. However, the Langat River is one of the main sources of drinking water to almost one-third of the population in Selangor state. Meanwhile, several studies have reported a high concentration of Arsenic (As) in the Langat River that is toxic if ingested via drinking water. However, this is a pioneer study that predicts the As concentration in the Langat River based on time-series data from 2005–2014 to estimate the health risk associated with As ingestion via drinking water at the Langat River Basin. Several time-series prediction models were tested and Gradient Boosted Tree (GBT) gained the best result. This GBT model also fits better to predict the As concentration until December 2024. The mean concentration of As in the Langat River for both 2014 and 2024, as well as the carcinogenic and non-carcinogenic health risks of As ingestion via drinking water, were within the drinking water quality standards proposed by the World Health Organization and Ministry of Health Malaysia. However, the ingestion of trace amounts of As over a long period might be detrimental to human health because of its non-biodegradable characteristics. Therefore, it is important to manage the drinking water sources to minimise As exposure risks to human health.
