Effects of Sand Mining on Palau’s Reefs Joshua Kloulubak SC-249: Environmental Concepts & Issues Instructor Sherry Ngirmeriil 21 July 2013 Abstract What are the negative effects sand mining has on Palau’s reefs? This research paper attempts to address the consequences of dredging erratically in the quest for modernization and what these threats can pose to the society should this continue in an unsustainable manner. Over the years‚ the ocean and reefs of Palau have been an important source

Water testing is carried out for ions‚ colour‚ pH‚ hardness‚ turbidity‚ conductivity‚ micro-organisms. Alternative methods of filtration such as membrane filtration may be both more efficient in removing particles including microorganisms such as Giardia and Cryptosporidium. However‚ these techniques are expensive to

PLANT LIFE IN SOFT BOTTOM COMMUNITIES 1. INTRODUCTION This paper deals with plants that are found in soft bottom communities that are either found in freshwater or marine environment. These plants are submerged therefore having different adaptation for this environment. These different adaptations were tackled in this paper as well as the physico-chemical parameters present in their environment. These plants have changes in their morphology to be able to cope with the environment. For example

Introduction My unknown organism #6 is Morganella morganii‚ which is a gram-negative bacillus rods commonly found in the environment and also in the intestinal tracts of humans‚ mammals‚ and reptiles as a normal flora. (3‚ 5) This bacterium Morganella morganii‚ was first discovered in the 1906 by a British bacteriologist named H. de R. Morgan. (2) Despite its wide

What my project is about: I will be comparing results from water testing I did at two different water bodies to prove that the catchment area has an influence over the water quality in the different water bodies. The first water body I tested was the small dam in the bokkie park situated in between residential areas and in the middle of a piece of land solely used for animals. The second water body I tested was the small dam across the road from the Trinity Church in Boksburg on Rondebult Road‚ which

These were: pH‚ fecal coliform‚ total coliform‚ total dissolved solids‚ turbidity‚ NH3-N‚ lead‚ BOD5 etc. Analysis results reveal that overall quality of water was quite satisfactory as per Bangladesh standards. Again from point of view of cost savings on installation and maintenance expenses‚ the system is quite effective and
