What could be causing the green tint by the sea?« Back to Previous Page

After the heavy storms we had last month, I noticed a strange greenish tint on the sand at the edge of our patio right by the sea. It looks like some kind of algae or mold, but it’s in such an odd spot that I’m not sure where it could be coming from. The kids have even started to complain about feeling unwell when they play outside. Where might this be coming from and how can we clean it up?

The green tint by the sea could be due to several factors. In Dubai and UAE, coastal areas are prone to various environmental conditions that can lead to such occurrences. It's quite likely you're seeing algae or a type of mold growing on the sand near your patio. This could happen for a few reasons.

Firstly, the recent heavy storms might have brought in more moisture than usual, which is perfect for fungi and algae growth. In Dubai, where we experience a combination of high humidity and direct sunlight, such conditions can create an ideal environment for microorganisms to thrive. Secondly, salt spray from the sea might also contribute to this growth as it could affect how the sand retains moisture.

However, given your concerns about the kids feeling unwell after playing in that area, it's important to rule out any potential health risks associated with such a condition. In Dubai, we do have regulations and guidelines for maintaining public health, especially regarding environmental quality near residential areas.

I recommend getting a professional inspection done. Contacting 800-MOLDS or emailing hello@saniservice.com could be beneficial as they can provide you with an assessment of the situation and advise on appropriate cleaning measures. They might also test to ensure that what you're seeing isn't something more harmful, like certain types of mold.

For now, it's a good idea to keep your kids away from this area until you get professional help. If you decide to clean up yourself, make sure to wear protective gear such as gloves and masks to avoid direct contact with the substance.

Cleaning can be done using basic disinfectants or fungicides that are suitable for outdoor use, but always follow the manufacturer's instructions carefully. It’s also worth checking if the area is prone to reoccurring issues so you can take preventative measures in future. Remember, safety and health should always come first.

In the meantime, keeping an eye on weather conditions and any changes in the sand could provide additional insights into what might be causing this issue.
