Important Aspects In The Phase I Environmental Site Assessments (ESAS)

By Della Monroe


A new factory or industrial installation is usually a project that evokes great interest, and one which people spend enormous sums on. They also dedicate large amounts of time and attention to the project. The planning and forecasting which go into the project are copious, and part of these are the Phase I Environmental Site Assessments (ESAS). This is an environmental assessment which is performed in order to detect the natural profile of the project area and what threats it contains, as well as its general suitability.

The environment needs to be taken into account and assessed. The modern attitude is that it should be recognized as deserving of respect. The opinion that pollution is insignificant or that the environment should be taken for granted is outdated and is not adhered to by modern governments or the community.

As a rule, then, developers should always take cognisance of the environment. They should maintain the approach that the latter needs to be preserved, not damaged or polluted. This is in keeping with the modern philosophy of conservation and respect.

The ESAS looks at several factors in the natural environment that are of extreme importance in determining the safety of the area. These factors are related to aspects of the environment that can potentially have an influence on human health and the ability of the area to sustain the development or planned activities.

One of these is the nature of the soil. Soil is important in assessing the environment because it absorbs and stores substances. Dangerous chemicals seep into the soil (a process known as leaching). These chemicals may originate from a variety of sources, such as dead animals, rotting plant matter or simply the rain. The soil then becomes poisoned and is not suitable for agriculture or other activities.

The soil is another aspect that should be examined. This sounds strange, but soil is not as innocuous as it looks. It absorbs any chemical that it comes into contact with, especially from sources such as animal carcases or decomposing vegetation. Poisons sink into the soil and remain, where they can potentially poison anything else. Poisoned soil is not suitable for crops or animal husbandry.

Undesirable plants are those species which are not wanted by the authorities in that specific area. This is almost always because they are not indigenous species. Alien plant species are a threat to the environment because they do not form part of the endemic food chain. They then cause a disruption in the food chain by absorbing too many nutrients or taking up too much space. They may also cause the soil quality to deteriorate. Unhealthy plants are those which have been poisoned or which are carrying diseases. Poisoned plants are sometimes eaten as fodder by insects and animals, and this is how the poison enters into the local food chain.

The water in the area also needs to be assessed. This is an easy assessment because the water harbors the toxins that are present in the soil and plants.

These are all significant aspects in the environmental assessment. In general, developers should not try to skimp on the assessment or eliminate it from their planning.
