7. Water Quality
Western Cape IWRM Action Plan: Status Quo Report Final Draft 7. WATER QUALITY 7.1 INTRODUCTION 7.1.1 What is water quality? “Water quality” is a term used to express the suitability of water to sustain various uses, such as agricultural, domestic, recreational, and industrial, or aquatic ecosystem processes. A particular use or process will have certain requirements for the physical, chemical, or biological characteristics of water; for example limits on the concentrations of toxic substances for drinking water use, or restrictions on temperature and pH ranges for water supporting invertebrate communities. Consequently, water quality can be defined by a range of variables which limit water use by comparing the physical and chemical characteristics of a water sample with water quality guidelines or standards. Although many uses have some common requirements for certain variables, each use will have its own demands and influences on water quality. Water quality is neither a static condition of a system, nor can it be defined by the measurement of only one parameter. Rather, it is variable in both time and space and requires routine monitoring to detect spatial patterns and changes over time. The composition of surface and groundwater is dependent on natural factors (geological, topographical, meteorological, hydrological, and biological) in the drainage basin and varies with seasonal differences in runoff volumes, weather conditions, and water levels. Large natural variations in water quality may, therefore, be observed even where only a single water resource is involved. Human intervention also has significant effects on water quality. Some of these effects are the result of hydrological changes, such as the building of dams, draining of wetlands, and diversion of flow. -

Date: July 2018 Coastal management lines for Eden District ii EXECUTIVE SUMMARY The coastal zone has always attracted people, whether for recreational purposes or for the natural resources that can be harvested from the coast or adjacent marine area. However, this concentration of people necessitates the concentration of developmental activities that are often in conflict with the natural dynamic nature of the coast or the biophysical sensitivities associated with the coastline. The Western Cape Government is under obligation to protect and preserve the inherent value of the Western Cape’s coastal zone. -
