What is that on our Lake

Over the past few years, we have observed an increase in various types of algae in the water at Lake Ontelaunee. Last year, a strain we were unfamiliar with caused operational issues that nearly disabled our filtration plant. Since then, RAWA has taken a proactive approach to monitor and treat algae to prevent future problems and has conducted extensive research on algae growth prevention. Algae problems do not resolve themselves naturally.

In recent years, we have also been experiencing increased drought conditions, which make controlling algae even more challenging. To address this issue, we have enhanced our monitoring efforts and purchased a microscope capable of identifying many forms of algae and recording our tests. Our highly skilled lab staff have been trained on this new equipment, and we have increased testing and monitoring tenfold. This enables us to anticipate and prevent potential issues before they become serious.

After careful consideration and consultation with industry professionals, we decided to install several next-generation, solar-powered, ultrasonic floating algae remediation solutions in addition to our lab testing and monitoring. Ultrasound technology is gentle and not harmful to other plants or aquatic life and helps protect drinking water utilities from harmful algae infestations and their impact on operations.

That is what you are now seeing on the lake.



We at RAWA are grateful for the vigilance of those who have been reporting sightings of these new devices to the police, DEP, and other authorities. We encourage you to continue doing so, as we are committed to maintaining the same high standards for access that have been in place for generations. It is essential to protect our drinking water supply from all potential threats.

Thank you for your continued support and understanding.

Sincerely,

Bill Murray

Executive Director, Reading Area Water Authority
