Your Pool is a Major Air Polluter

An aerial view of the suburbs in a warm climate often displays a homogenous cluster of houses, spiraling outwards along the street. Behind each house, a fenced, green patch contains a sparkling pool in a kidney-bean shape – or perhaps round or rectangular.

These toxic puddles are more than Kool-aid blue splashes on an otherwise bare landscape. They are generators of air pollution. Especially in large concentrations.

Staying out of artificial swimming pools doesn’t keep you free from exposure to the toxins contained within. Whether they are actually used, the congregation of chemically treated pools elevate the pollution levels throughout the entire neighborhood. This can be done through evaporation.

Evaporation can occur year-round in all climates, but occurs at higher rates in dry climates – less so when the air is humid. As pools are more often found in neighborhoods of hot, dry cities, they will have a greater percentage of water loss.

In Sydney, Australia, the average pool can lose a daily amount of 5.3 – 7.4 mm of water for every square meter of pool surface area. This would be the equivalent of 200-plus liters (52.83 gallons) per day. During the six-month swimming season, you may be losing well over 10,000 liters of water a month.

In Perth, Australia, for example, an average of 10,435 liters of water is lost to evaporation each month (during the six-month swimming season). In addition, another 3,000-plus liters will be lost during the other half of the year. The equivalent of about 792 gallons.

A pool of 20,000 gallons of water will contain around 2 pounds of chlorine. With the above evaporation rates considered, we can infer that with a pool this size in a similar climate, more than 5 ounces of chlorine will also enter into the air, with the water, through the evaporation process.

Five ounces per month. This may seem minute. However, the numbers quickly add up when considering areas with high concentrations of of pool water.

Let’s assume, for example, you live a neighborhood in an arid climate. In this neighborhood, are twenty houses, fifteen of which have an artificial pool in their backyard. If each pool contains 20,000 gallons of chlorine treated water, releasing 5 ounces of chlorine into the air each month, all would contribute to a total of 75 ounces of chlorine released. Or 4.6 pounds per month.

Because toxins are able to rise and move about freely through the air, they will have a negative impact on all residents of the neighborhood, even to those who have had no contact with the water. This could cause eye and skin irritation, along with irritation of the throat and mucus membranes. While long term exposure to air pollutants can lead to asthma and other illnesses.

These toxins effect everyone, but are particularly hazardous to children, whose lungs are still developing, as well as the elderly and those living with respiratory problems.
