I am not sure what "pesticide ridden bacteria" could be.
Pesticides are chemicals designed to kill insects and some plant diseases. Pesticides themselves are mostly poisons to animals. But pesticides are not alive.

But molds, and algae yes. These simple organisms may infect people and cause illness. Molds actually can live in people. The algae tend to dump toxins into the bodies of mammals, and these toxins are byproducts of their metabolisms.

I have seen algae mats upNorth where water is shallow. You might have those. They are dark green and sometimes look even black. They cover the bottom of the pool as a rule, but when thinner they float around and may wash up with waves.

I think you might reconsider so much barefoot activity and opt for water shoes, crocs etc.

Pesticides kill insects. And bacteria are everywhere. Algae are neither.
https://en.wikipedia.org/wiki/Algae
Algae can be considered to be primative plants.

https://en.wikipedia.org/wiki/Bacteria
Bacteria are considered to be primative animals.
If pathogenic they can live inside people and cause infections.

cyanobacteria: These are bacteria with photosynthetic ability. Often considered the first forms of life on the evolving earth in the beginning of this planet.

Health risks
Main article: Cyanotoxin

Cyanobacteria can produce neurotoxins, cytotoxins, endotoxins, and hepatotoxins (i.e. the microcystin-producing bacteria species microcystis), and are called cyanotoxins.

Specific toxins include, anatoxin-a, anatoxin-as, aplysiatoxin, cyanopeptolin, cylindrospermopsin, domoic acid, nodularin R (from Nodularia), neosaxitoxin, and saxitoxin. Cyanobacteria reproduce explosively under certain conditions. This results in algal blooms, which can become harmful to other species, and pose a danger to humans and animals, if the cyanobacteria involved produce toxins. Several cases of human poisoning have been documented, but a lack of knowledge prevents an accurate assessment of the risks.[48][49][50] Recent studies suggest that significant exposure to high levels of some species of cyanobacteria producing toxins such as BMAA can cause amyotrophic lateral sclerosis (ALS). The Lake Mascoma ALS cluster [51] and Gulf War veterans' cluster are two notable examples.
It is these toxins the cyanobacteria produce that are toxic to animals and people.
