Swallowing Water While Swimming

Have you ever wondered how much water you actually swallow while swimming in a pool?  We did too so we decided to find out. 

In 2006, the EPA did a pilot study titled "Water ingestion during swimming activities in a pool."

What the study revealed was that a non adult would ingest 37 Milliliters of water over a 45 minute period.  This converts to 1.6 ounces of water every hour a non-adult is in a swimming pool.  

If a non adult with access to their swimming pool of that of a friend or relative spends an average of three hours a day in a pool all summer long, they will ingest 480 ounces of pool water per summer.  That is  3.75 GALLONS every summer.

That is a lot of water.  It also is a reminder to have your pool water correctly sanitized and balanced in accordance with the Langelier Saturation Index.  

Something to think about.
