  • 垃圾倾倒已经污染了五条流域
        由污水排放以及固体垃圾倾倒引起的微生物污染影响了位于Kerala五条河流的水质,急需对水资源进行更严格的监控以及管理。
    该研究主要针对Kasaragod地区Mogral,Chittari以及Shiriya河流,Idukki地区的Pambar河流以及Attappady地区的Bhavani河流,其研究成果已经被水资源发展以及管理中心发表。该研究作为针对水质环境检测项目的一部分,由Kerala地区科学,技术与环境委员会负责实施。

    污水排放检测
        该研究表明Mogral流域67%的水样水质较差,23%的水样水质刚刚达标。Mogral流域中大部分的上覆水经过传统的处理与消毒后能够被用来饮用。在Mogral kadavu检测到了污水的直接排放,其中固体废弃物倾倒被认为是河口地区的主要问题。所有Pambar流域的水样水质刚刚达标,这表明只有经过消毒后才能够被用来引用。最严重的微生物污染发生在雨季前。

        Chittari流域的样品分析表明25%的水样质量较差。被大肠杆菌污染的样品百分比在雨季较高。下游地区污染更加严重,在Madiyan thodu地区的污染最为严重。
        Bhavani流域的水质由好至逐渐较差。最严重的微生物污染发生雨季前。最严重的有机降解发生在Kakkapady。
        Shiriya流域表层水样品的分析表明20%的水样质量较差,80%的水样质量刚刚达标。最严重的微生物污染发生在雨季前。在Angadi Mugar 以及 Adkasthala 桥附近是污染最为严重的地点。80%的地下水样品在进入雨季前就已经被微生物污染。
    有机氯杀虫剂的浓度在所有五个流域中的浓度都低于检出限。

    • Dumping has hit five river basins Microbial contamination due to sewage discharge and dumping of solid waste has affected the water quality in five river basins in Kerala, highlighting the need for stricter monitoring and management of water resources. The findings have been published by the Centre for Water Resources Development and Management (CWRDM) based on a study of the Mogral, Chittari and Shiriya river basins in Kasaragod, the Pambar river basin in Idukki, and the Bhavani river basin at Attappady. The study was carried out as part of the Environmental Monitoring Programme on Water Quality taken up by the Kerala State Council for Science, Technology and Environment. Sewage input detected The survey revealed that 67% of the water samples collected from the Mogral river basin were of poor quality while 23% were of marginal quality. The majority of the surface water samples from the Mogral could be used for drinking only after conventional treatment and disinfection. Sewage input was detected at the Mogral kadavu while solid waste dumping was identified as a major problem near the mouth of the river. All the water samples collected from the Pambar river basin were found to be of marginal quality indicating that the water could be used for drinking only after disinfection. Maximum microbial contamination was reported in the pre-monsoon season. Analysis of the samples from the Chittari basin revealed that 25% were of poor quality. The percentage of E.coli contamination was found to be high in the monsoon season. The downstream areas were more polluted, with Madiyan thodu recorded as the most polluted location. The water quality in the Bhavani river basin ranged from good and fair to marginal. The maximum microbial contamination was reported in the pre-monsoon season. A high degree of organic degradation was reported from the Kakkapady site. Analysis of the surface water samples collected from the Shiriya river basin showed that 20% were of poor quality and 80% of marginal quality. Maximum microbial contamination was in the pre-monsoon season. The area near the Angadi Mugar and Adkasthala bridges were the most polluted locations. Up to 80% of the groundwater samples were also bacteriologically contaminated during the pre-monsoon season. The concentration of organochlorine pesticides was found to be below detection limit in all the five river basins.
