On July 8, 2020, the Mayor of Hopatcong was on hand to watch over the start of his New Jersey Department of Environmental Protection (NJ DEP) Grant Project. This initiative was driven by the Mayor, while the official Lake Hopatcong Commission, Lake Hopatcong Foundation and Princeton Hydro filed the majority of other Grant requests. The Mayor filed his request to ensure that Crescent Cove was included in the process.

What are Nanobubbles and how will they help?

Nanobubble aeration is a new technology designed to naturally control algae by increasing the oxygen in the water. On-shore generators will produce nanobubbles that are ultra-fine (400 times smaller than a human hair) that will remain within the water column for extended periods, providing oxygenation and algae control.

The new nanobubble technology is designed to naturally improve water quality by exceeding the oxygenation capabilities of aeration systems. Nanobubbles are produced by an on-shore gas transfer mechanism that creates ultra-fine bubbles that are nearly invisible to the eye; in fact, at less than 1 micrometer, they are about 400 times smaller in diameter than human hair and 1 million times smaller than ordinary bubbles. As a result of their size, nanobubbles have no natural buoyancy. Unlike floating fountains and submersed aeration systems, which use rising larger bubbles to induce circulation and transfer of atmospheric oxygen throughout the water column, nanobubbles remain within the water column for extended periods of time, providing direct oxygenation of the water.

Another interesting characteristic of nanobubbles is that they are negatively charged and, therefore, are attracted to positively charged organic matter in the water column. When they connect with positively charged metals, pollutants and dangerous cyanotoxins, nanobubbles render them inactive to keep them from causing undesirable water quality conditions. While nanobubbles are traditionally infused with oxygen from the atmosphere, they can also be infused with concentrated oxygen from small onshore generators that can easily be added to the system where faster or more immediate results are needed.

  • Saturates water with up to 79,000x more oxygen than aeration
  • Helps mitigate excess nutrients and harmful toxins
  • Aims to sustain the rapid growth of beneficial bacteria and desirable microbes
  • Helps prevent accumulation of anaerobic bottom muck and sediments
  • Can remain within the water column for more than 2-3 months

NJ DEP GRANT not for the Full Amount

While this is still great news for Crescent Cove, the N.J. Department of Environmental Protection (DEP) stated that only a portion of his grant request for battling the Harmful Algae Blooms (HABs) has been approved.

The grant to Hopatcong was only for $125,000, not the $250,000 requested for the four biological treatments of Crescent Cove. 

This marks another GREAT PROJECT improvement happening on our lake.
