There are huge algal blooms growing in many waters off the coast, in lakes and rivers near where large populations reside. Most of this comes from human use of farm chemicals and fertilizers used on golf courses. It’s a big problem and here is a drinking water problem in the Las Vegas Lake Powell area;

The way to cure drinking water in Lake Powell and drinking water outside of Wichita KS with a similar problem is to use microencapsulation technologies to allow slow release of biosensitive chemicals to reduce Bloom. It was said that in a problem like this; High levels of nutrients in bodies of water, eg swimming pools in waterways with high levels of N, the best solution to the problem is the following: trial application of zeolite to extract N from the water column will allow a slow release for plant use. Macrophytes (eg, pond biofilters) will use N from the zeolite Flocculant zeolite in the water and then add microbes to break down the algae blooms. But by using microencapsulation technologies, you can fix it without the complicated problems.

If the encapsulated chemicals become loaded, they will stick to the bloom and slowly release and solve the problem. This is not to say that watershed or BMP issues associated with local NPDES permits should not be followed by point source discharges. There have been many very complex and expensive ideas to fix the Lake Powell problem, but I think the problems are simpler than that, same with The Cheasapeak or even the Gulf of Mexico off the coast of Naples and Ft Myers FL. Any questions on this subject please post an answer.

There are many companies working on this, here is one that we investigated in our study;

Water is important and we must be careful to protect it and address these issues at superfund sites and in cases of our past lack of knowledge of the complex factors that make up our ecosystem. Think about it.
