The aim of this study was to make a diagnosis of coastal pollution through bacteriological analysis of water taken from stormwater drain systems and the nearby seashore. The results were submitted to statistical analysis as to differences in the Most Probable Number (MPN) of fecal coliform (FC) found between the stormwater drain systems and adjacent seashore locations both at low and high tides...

At present, many metropolitan sewer systems do not meet existing and proposed standards on water pollution. Existing systems were designed to overflow at prescribed locations in order to protect the sewage treatment plants whenever severe overload conditions exist (usually during storms). This discharge of untreated overflows into natural receiving waters is of growing concern to water pollutio...

MOST SEWAGE COLLECTION and treatment systems in the U.S. are 30 to 100 years old [EPA(b)] with a total estimated value exceeding $1 trillion [EPA(a)]. EPA estimates that in the year 2000, more than 1.2 billion gallons of raw sewage poured into waterways due to overflow, blockage, leakage or other system faults [EPA(b)]. The construction projects needed to correct these problems will be many and...

conserving water resources and protecting them from pollution are of high account in the natural cycle of our life. this study has tried to determine the refining potential and capacity of water hyacinth (eichhornia crassipes) in order to remove the cadmium from water, studying the influence of factors such as initial concentration of cadmium, contact time, absorbent mass, and ph. results have ...

Most current pollution management in cities is based on treating pollution at the end-of-the pipe, after pollution is generated. This paradigm worked well for treating municipal sewage and industrial effluents – point sources of pollutants. Pollution from these sources has been greatly reduced since passage of the Clean Water Act in 1972. However, the remaining pollution problem in post-industr...
