Burned forests impact water supplies

Chemical contamination of water supplies.

Man-made organic chemicals have been found in drinking water for many years. Their numbers and varieties increase as our analytical capabilities improve. The identified chemicals comprise 10 to 20% of the total organic matter present. These are volatile or low molecular weight compounds which are easily identified. Many of them are carcinogenic or mutagenic. Chlorinated compounds have been foun...

Mapping Burned Areas in Tropical forests using MODIS data

1 This paper presents a new burned area product for the tropical 2 forests in South America and South-east Asia. The product is derived 3 from Moderate Resolution Imaging Spectroradiometer (MODIS) mul4 tispectral surface reflectance data and Active Fire hotspots using a 5 novel rare class detection framework that builds data-adaptive clas6 sification models for different spatial regions and lan...

Bacterial nitrification in chloraminated water supplies.

Nitrifying bacteria were detected in 64% of samples collected from five chloraminated water supplies in South Australia and in 20.7% of samples that contained more than 5.0 mg of monochloramine per liter. Laboratory experiments confirmed that nitrifying bacteria are relatively resistant to the disinfectant. Increased numbers of the bacteria were associated with accelerated decays of monochloram...
