Arsenic: Some 80 million people of Bangladesh are now at risk of Arsenic contamination. This was revealed from the latest survey jointly conducted by DCH and SOES. After analyzing the data, experts opined that groundwater Arsenic contamination and sufferings of peoples in Bangladesh may be the biggest Arsenic calamity in the world. However, after testing the water of tube-wells of several districts, the survey did not found alarming level of Arsenic. Arsenic was found less than 0.01 mg/l in these samples. These districts can be considered as completely safe from Arsenic pollution. One of these 8 districts is Naogaon. The Public Health Engineering Department of the Government of Bangladesh examined of tube well water samples in some southern districts and concluded that Naogaon is one of the "Contamination Free Districts". On the contrary, examinimg various areas, BAMWSP targeted some areas of bangladesh as Arsenic Prone Upazilas where Porsha of Naogaon had 28th place as in Phase 1 and 2, and Manda of Naogaon had 95th place as in Phase 3. According to some experts, the percentage of arsenic-affected tubewells is between 20 and 40 in Naogaon district. Proshika located Naogaon as one of the least affected district (2%). "Even in areas of low arsenic concentrations, there are some 'hot spots' where a cluster of wells with unusually high concentrations of arsenic exist. Such 'hot spots' are dispersed but most noticeable in northern Bangladesh. We investigated one such 'hot spot' in Chapai Nawabganj and estimated that it was about five kilometers by four kilometers in extent'', the study said.

Flood: Further to heavy rainfall in West Bangal and water flow from the upper catchment areas of India, flood waters enters Bangladesh in last quartrs of about each year.  Flood waters spread to deeper in Bangladesh over Naogaon. The affected population can be divided into two categories;  those remaining in flooded areas and those who have sought refuge in shelters established by the local community, private individuals, the local administration and NGOs. A  few  deaths  have  been reported each year. Millions of people are believed to have been affected by the floods in affected districts. Very few boats were available locally for relief and rescue operations, since major rivers in the area are rare.  This shortage of vessels has in part been offset by the use of army and navy boats, and by the arrival of boats from neighbouring districts, but these still fall short of requirements.  As floodwaters begin to recede the use of boats will be restricted and possibilities for transport will be further curtailed.  It is therefore essential that relief supplies be delivered to affected areas before communications become more difficult. Large numbers of tube wells have been inundated and may need to be resunk, and there has been widespread arsenic contamination.  80 to 90% of houses in the area are built of mud, which is unlikely to have withstood the onslaught of the floods.  Most of these houses will have to be reconstructed. Rice due to be harvested in November has been seriously affected by the floods.   Other crops severely affected and destroyed.  Tons of husked rice and vegetable crops have been lost. Poultry and goats were washed away by the sudden floods.  Larger animals usually survived the floods, but families are selling their livestock for much-needed cash as fodder is scarce in the shelters, and animal theft rife. The Ministry of Disaster Management and Relief (MDMR) has so far has been allocating cash and rice to this affected district Naogaon[1].
