Unfortunately it appears that the liquid running into the ocean last week was indeed highly toxic coolant fluid.
WC, CAPE TOWN, SEA POINT
Please see below the official reply from the City of Cape Town, Note: this is not a “story” and although we would all like it to be harmless tracing dye it is not, and as suspected remains coolant and is TOXIC. Please refrain from making unnecessary and derogatory statements. The point of this post is informative and to give those of us who care an opportunity to make a change.
Hi, we appreciate your interest and concern. We have identified the green liquid as a coolant used for commercial building cooling systems. These coolants may also appear in blue and pink. We have identified most of the main manufacturers of this substance, as well as the companies that service commercial building cooling systems in the Cape Town area. These companies are responsible for correctly disposing of excess or used coolant when servicing cooling systems.
We will be engaging with the various companies with the intention of making them aware of their responsibilities and the fact that it is illegal to discharge this substance in to the City’s stormwater system.
We will also distribute information to residents and businesses in the Sea Point, Green Point and Camps Bay areas with the intention to:
• Inform the public of the challenges we are facing with regard to pollutants being discharged into the stormwater system and the consequences this has for water quality in the coastal environment
• Inform residents and businesses of where and how to discharge various waste household and commercial waste products in accordance with the City’s standards
• Provide a range of City contact numbers and email addresses for the public to use should they witness any illegal discharge of substances into the stormwater system
Thank you so much for contacting us.
