Answer 1

Answer:

Algae is one of the most common, and annoying, problems faced by water treatment plants and wastewater treatment plants. It’s a problem that requires swift action to ensure that it does not affect production or release toxins that could change the properties of the water. To combat this problem, many believe that applying a copper sulfate solution to the infected water will reduce and cure algae blooms. While this method has been widely used and promulgated, it is an ineffective and dangerous solution to a safely treatable problem. Here are ten reasons not to use copper sulfate as a solution to your algae bloom infestation.

10 Reasons

It doesn’t treat the causes of algae in your pond. When it is applied to an infected water location it can treat only the visible symptoms of algae. Instead of targeting the nutrients that cause the algae to grow in the first place, it only targets algae itself. For this reason, copper sulfate becomes ineffective—it kills the algae, which then sinks to the bottom of the pond where it decays and releases additional toxins which can create more blooms, essentially resulting in a larger problem than you started with.

It is toxic to humans. When used to combat algae blooms in water, copper sulfate can create a hazard to humans. Since copper sulfate is easily absorbed through the skin, those that dispense it must be extremely cautious to avoid even minimal skin contact with it. If contact occurs, it can cause itching and permanent yellow discoloration of the skin. Additionally, if ingested (through inhalation of the powder or through drinking it) copper sulfate can cause immediate vomiting, and if retained in the stomach: unconsciousness, burning pain, nausea, diarrhea, headache, shock, and unconsciousness. These risks are documented by the EPA who have classified copper sulfate
