A literature review on Sri Lankan water quality statistics and associated problems would involve a comprehensive analysis of various sources that discuss the state of water quality in Sri Lanka and the challenges it faces. Here is a brief overview:

1. **Introduction**: Sri Lanka, an island nation in South Asia, is known for its diverse landscapes and rich biodiversity. However, the country faces significant challenges in maintaining water quality, primarily due to industrial pollution, agricultural runoff, and inadequate sanitation facilities.

2. **Water Quality Statistics**: According to the World Health Organization, nearly 85% of Sri Lanka's population has access to improved water sources. However, the quality of this water varies significantly. A study by the National Water Supply and Drainage Board (NWSDB) found that only about 40% of the country's water supply is considered "safe" by international standards. The water quality in rural areas is particularly concerning, with high levels of bacterial contamination and heavy metals.

3. **Problems Associated with Water Quality**: The poor water quality in Sri Lanka has significant health implications. Waterborne diseases such as diarrhea, typhoid, and hepatitis A are common. Additionally, the presence of heavy metals in water sources can lead to long-term health issues like kidney disease. A study published in the International Journal of Environmental Research and Public Health linked the high prevalence of chronic kidney disease in Sri Lanka's North Central Province to the consumption of water contaminated with heavy metals.

4. **Contributing Factors**: Several factors contribute to the poor water quality in Sri Lanka. Industrial pollution is a significant issue, with factories often discharging untreated waste into rivers and streams. Agricultural runoff, containing pesticides and fertilizers, also contributes to water pollution. Furthermore, inadequate sanitation facilities, particularly in rural areas, lead to the contamination of water sources with human waste.

5. **Efforts to Improve Water Quality**: The Sri Lankan government, along with international organizations, has implemented several initiatives to improve water quality. These include the construction of new water treatment facilities, stricter regulations on industrial waste discharge, and programs to educate the public about the importance of water conservation and sanitation.

6. **Conclusion**: While progress has been made, significant challenges remain in improving water quality in Sri Lanka. Continued efforts are needed to address industrial pollution, agricultural runoff, and inadequate sanitation facilities. Further research is also necessary to better understand the health implications of poor water quality and to develop effective strategies for water management and conservation.

This is a brief overview and a more detailed review would involve a deeper analysis of each of these points, including a review of specific studies, data analysis, and a discussion of potential solutions.
