Presentation Of Data:

Introduction- The Cipero river is located in San Fernando in the district of Victoria, South of Trinidad. It is located at an elevation of about 1 metre above sea level and the coordinates are 10°16'0" N and 61°28'0" E. The distance of the Cipero is approximately 25 miles away from Port Of Spain, the Capital of Trinidad and Tobago and the compass direction from Port Of Spain is South South-East.

Table 1- showing various points at the river and the pH.



Table 2- showing various points and velocity



Analysis And Discussion:

Table 3



As seen in table 3, due to the dumping of garbage and other effluents disrupted the smoothness of the river. The velocity of the river varied because of this and the natural relief of the positioning of the upper and lower courses. Another observation that was deduced was that the width of the river allowed more garbage to be accumulated, decreasing the velocity. The causes responsible for this are the garbage and household disposals. These conclusions were deduced from points 1-7.

The reasons for the pH being as it is (refer to table 1), is perhaps linked to the obervations made from the effluent from industrial waste water and the run off of pesticides from agricultural grounds nearby. An interviewed was conducted with the person who owned the agricultural ground in which he said that the industry nearby dispose their waste into the river as was seen as well. The pH of the water was supposed to be neutral ( pH 7) but as tested, it was slightly over 7. Another interviewed was conductor in which the person resides near the river where the water was stagnant and accumulated most of the garbage at the sides of the river. As a result, flooding occurs and it turns to a breathing ground fro mosquitoes. The person said that one year, there was a massive flood which reached the height of half of the electricity poles. Once again, the pH of the river was altered various points of the river due to the effluents from the industry nearby and household pollutants which affected the marine life.

Causes
Consequences
Dumping of Garbage
Blockage of the river course hence causing flooding and contaminated water. Repulsive odor obtained by garbage in which residents nearby are disturbed Household waste water flowing into river
Water turns a green colour showing presence of algae due to build up of nitrates Oil floating on an area (refer to table 1) on the surface of the water allows fish to breathe and live in such condition and as a result the fishes are dead Industrial Pollution

Oil was seen floating on the water (refer to table 1) which causes the destruction of marine life. Flowing of pesticides and herbicides from agricultural grounds Harmful toxins from the pesticides and herbicides poisons marine life (organisms) due to the lack of oxygen that is not present anymore...
