a.

Summary Introduction

To describe:

The test used to analyze the water quality in recreational areas.

Introduction:

The water percentage on Earth is about 97.5% in the form of vast oceans. But only 2.5% water is available as freshwater. The human activities like overexploitation of freshwater, introduction of pollutants into water bodies and using chemical fertilizers in crops that seep into water are leading towards depleting water resources.

b.

Summary Introduction

To determine:

The way by which information can be conveyed to the beach supervisor about the contamination of Enterobacter species in the water.

Introduction:

Water quality is important for good river health. It sustains ecological processes that support fish populations, vegetation, wetlands and bird. Many species directly depend on water for basic needs. If the quality of water is not fit for consumption, then it will affect the health of the organisms.

c.

Summary Introduction

The reason of little tolerance for fecal coliforms in recreational or drinking water.

Introduction:

Water quality is important for good river health. It sustains ecological processes that support fish populations, vegetation, wetlands and birdlife. Many species directly depend on the water for basic body need; if the quality of water is bad then it might affect the health of the organisms.
