BBRAeNews No.23 - Preserving Our Lakes from Pollutions.

Environmental Externalities and Some Possible Solutions To Prevent Pollutions and Contaminations to Our Botanical Lakes and Streams.

I want to look at a variety of issues that may arise with a water supply into our Botanical Lakes. I will do this by bringing up a variety of sources of pollution and some suggestions that may help solve the environmental externalities. Let me first mention that this hypothetical water supply may comes from a river that runs through a variety of landscapes and thus land uses including woodland areas near the tributaries then through a variety of rural and suburban built up areas and then into our Botanical Lakes and Streams.
A source of environmental externalities is from used motor oil or cooking oil or even detergent dumped into storm drains. Since the source is widespread and happens at random occurrences most methods of enforcement fines is of little prevention for events that can damage 250,000 gallons of drinking water or 1 million gallons of fresh water from one quart of used motor oil or used cooking oil or detergent. A good propaganda campaign can inform residents & shop owners individuals as to what the consequences of their actions are and appeal to their community consciousness. This does negate having fines and penalties but would do little good when the chances of getting caught are very low but the damage can be so severe.

The second source to affect our water source is acid rain caused by industrial plants emitting SO2 into the atmosphere. I assume that the present levels of SO2 gas does not create problems but could if industry expands or emits more SO2 in the future.

The third source of pollution spilling into our lakes is raw sewage and garbage from a variety of types of septic tanks or gravity flow drainage systems. When heavy rains or flooding occurs, this raw sewage (along with all the bacteria) and garbage is carried downstream. The easiest way to solve this problem is to take over waste removal especially in areas (households and shops) that may leak into the lakes water system.

Sedimentation is the fourth factor affecting our river water source. During the process, the amount of sentiment can be given a weight based on techniques used, areas covered, time of year, and other factors that can be determined. Sedimentation is bound to occur.

In conclusion, I used a variety of techniques to either internalize the environmental externalities on a river water source or to at least account for how our residents can deal with those pollution problems.

Continuous Propaganda can influence residents’ decision to raise the level of concern for these environmental issues.
