The Downside of Chlorine in Well Redevelopment

Why It's Not the Best Option 

When it comes to well redevelopment, the use of chlorine has been a common practice for disinfection and cleaning. However, while it may seem like a quick and effective solution, there are significant downsides to using chlorine in this process.

 

In this technical article, we'll explore why chlorine may not be the best option for well redevelopment and discuss alternative methods that can yield better results. 

 

Chlorine, a powerful disinfectant, is often used to kill bacteria, algae, and other microorganisms in wells. While it can effectively eliminate these contaminants, it also comes with several drawbacks that can impact the overall health and productivity of the well. 

 

First and foremost, the use of chlorine can lead to the formation of harmful disinfection by-products (DBPs) such as trihalomethanes (THMs) and haloacetic acids (HAAs). These by-products are known to be carcinogenic and can pose serious health risks to those who consume water from the treated well. Additionally, the presence of DBPs can lead to regulatory compliance issues, as water quality standards become increasingly stringent. 

 

Moreover, chlorine treatment can also have a detrimental impact on the well infrastructure itself. It can corrode metal components, deteriorate well screens, and cause damage to pumps and other equipment. This can result in increased maintenance costs and a shorter lifespan for the well, ultimately leading to more frequent and costly repairs.  Furthermore, the effectiveness of chlorine in eliminating certain types of bacteria, such as iron bacteria and sulfate-reducing bacteria, is limited. These bacteria can form stubborn biofilms that are resistant to chlorine, leading to recurring contamination issues and reduced water quality. 

 

So, if chlorine isn't the best option for well redevelopment, what alternatives are available? One effective and environmentally friendly approach is the use of BoreSaver Ultra C and mechanical surging. This method can dislodge and remove sediment, biofilms, and other obstructions without the use of any harmful or damaging chemicals such as chlorine or hydrochloric acid. Thus, preserving the integrity of the well and ensuring long-term water quality. 

 

In conclusion, while chlorine has been traditionally used in well redevelopment for its disinfection properties, its negative impact on water quality, well infrastructure, and regulatory compliance make it a less than ideal choice. By exploring alternative methods and technologies, well owners and operators can achieve sustainable and long-lasting results without compromising safety or well integrity.
