Treatment Options for Contamination in Well Water Systems

Various water treatment disinfection methods are available to address bacterial contamination, ranging from boiling water to advanced treatment systems. The following processes aim to eliminate harmful bacteria that can cause health issues.

First Steps in Assessing Water Quality in Private Wells

Fraser Valley water well owners should conduct a thorough water quality test to identify bacterial presences, such as E. coli or coliform bacteria.

Accredited water testing laboratories serving the Lower Mainland can reveal the types and concentrations of bacteria and guide the selection of appropriate treatment options.

Boiling Water is Quick and Good for Emergencies

Boiling is widely recommended and effective for treating contaminated well water, especially in emergencies or when other disinfection methods are unavailable.

Bringing water to a rolling boil for at least one minute is sufficient to kill most types of pathogens, including bacteria, viruses, and protozoans.

Water should be boiled for at least three minutes in areas above 2,000 meters (6,562 feet) due to the decreased boiling point.

Water Disinfection: Chlorination

Adding chlorine to contaminated well water can effectively destroy bacteria. This method involves carefully dosing with an injection pump system and monitoring chlorine levels to ensure disinfection while avoiding an adverse taste or smell.

Ultraviolet (UV) Disinfection: The Modern Method for Safe Water

Ultraviolet (UV) light disinfection is a chemical-free method for purifying water that works by inactivating or killing microorganisms. Here’s a more detailed explanation:

 

1. How it Works: UV disinfection uses UV light, particularly UV-C light, which has a wavelength that is effective at disrupting the DNA and RNA of microorganisms.
   
   This disruption prevents the microorganisms, such as bacteria, viruses, and protozoa, from reproducing and causing infection.
   
   
2. Requirement for Clear Water: UV light must penetrate water to reach microorganisms. The source water needs to be clear for UV disinfection to be effective. Sediments or particulates in the water can shield microorganisms from UV light, reducing the effectiveness of the treatment.
   
   Hard or iron water exceeding the MAC will scale (coat) the quartz sleeve covering the UV lamp, reducing its ability to disinfect water.
   
   
3. Maintenance and UV Bulb Replacement: Regular maintenance is essential for UV light disinfection systems. It’s important to replace the UV bulb annually, as its effectiveness reduces over time.
   
   Even if the bulb continues to emit light, its disinfection capability diminishes, which is why routine replacement is necessary.

Effectiveness: UV disinfection is highly effective against many pathogens, including those resistant to chlorine, such as Cryptosporidium and Giardia. Ultraviolet does not remove chemical contaminants and heavy metals or improve the taste or odor of water.

In summary, UV light disinfection is a powerful, chemical-free method to purify water, particularly effective against various pathogens, as long as the water is clear and the system is well-maintained.

Water Filtration Systems: For Bacteria in Water?

Some filtration systems, like reverse osmosis, reduce bacterial levels and other contaminants. Using activated carbon filters alone is not enough to remove waterborne bacteria. Additional disinfection methods are necessary.

Well Water Disinfection: Ozonation

Ozone gas is nature’s most powerful disinfectant that eliminates bacteria and viruses from well water. Although effective, this method requires specialized equipment and technical knowledge.

Well Water Disinfection: Distillation

Distillation produces highly purified water by boiling and condensing the steam, removing bacteria and other impurities. It is a rigorous but energy-intensive process.

Maintenance and Regular Water Well Monitoring:

Regular maintenance of treatment systems and water testing is necessary to ensure they operate effectively and provide safe, bacteria-free water.

Considerations for Water Treatment System Selection

Rising Threat of Antibiotic Resistance in Well Water Systems

Guaranteeing the quality and safety of drinking water sourced from private wells in the Fraser Valley depends on adhering to both provincial and national guidelines. Understanding these regulations is essential to ensure the water meets drinking standards.

Antibiotic resistance in water systems, including wells, poses a significant public health concern. Well water, often used in rural or semi-urban areas, can become contaminated with antibiotic-resistant bacteria, notably strains of Escherichia coli and Pseudomonas aeruginosa.

These bacteria, which can thrive in anaerobic (oxygen-free) environments typical of some wells, have resisted multiple antibiotics due to their overuse and the improper disposal of pharmaceuticals. This situation may worsen in areas near agricultural or industrial sites where disposal is common.

Bacteria in well water complicate the treatment water that may cause waterborne illnesses, requiring vigilant monitoring and treatment protocols as recommended by water treatment experts in the Fraser Valley.

Climate Change and Its Impact on Well Water Microbiology

Global climate change further compounds these microbial challenges in well water systems. Rising temperatures and altered precipitation patterns can change the microbial ecology of well water, potentially enhancing the growth and spread of pathogens.

Waterborne pathogens like Vibrio cholerae and Salmonella enterica, which thrive in warmer temperatures, pose increased risks.

These pathogens can find their way into well water, particularly if the wells are shallow or inadequately protected. there are many shallow wells in use in the Fraser Valley and many of them have rarely been tested.

Additionally, climate change can affect the abundance of non-pathogenic microorganisms in water, influencing the survival and proliferation of pathogenic species through ecological interactions.

Addressing Water Safety: Vigilant Monitoring and Treatment

In summary, the intersection of antibiotic resistance and climate change impacts presents significant concerns for the safety and quality of well water. This situation necessitates a heightened focus on monitoring, protecting, and treating well water sources.

Understanding how these factors influence the microbial composition of well water is crucial for preventing outbreaks and ensuring the health and safety of those relying on this vital resource.

Frequently Asked Questions: Bacteria in Well Water

This clarifies common concerns about water safety, focusing on bacteria-related questions that individuals frequently have.

What are the health effects of bacteria-contaminated water?

Consuming bacteria-contaminated water can lead to gastrointestinal illnesses, with symptoms ranging from diarrhea and vomiting to more severe conditions, depending on the pathogen involved.

What are the most common types of bacteria found in well water?

Water sources can harbor various bacteria, including coliforms like E. coli, often indicators of fecal contamination, and pathogens like Salmonella and Campylobacter.

What is the deadliest bacteria found in water wells?

Determining the “deadliest” water bacteria in private water wells in British Columbia is not straightforward. The impact of a bacterial contaminant can depend on various factors, including the presence and concentration of the bacteria, the condition of the water well, and the health and immunity of the individuals consuming the water.

However, a few bacterial contaminants are particularly notorious for their potential health impacts:

1. E. coli (Escherichia coli): Some strains of E. coli, especially E. coli O157:H7, can cause severe illness, including bloody diarrhea and a potentially fatal kidney condition called hemolytic uremic syndrome. E. coli is a common contaminant in water sources contaminated by fecal matter.
   
   
2. Legionella pneumophila: This bacterium causes Legionnaires’ disease, a severe form of pneumonia. It can be found in various water systems, including wells, especially when the water is warm and poorly maintained.
   
   
3. Salmonella: Certain strains of Salmonella can cause serious illness, especially in vulnerable populations like the elderly, young children, and those with weakened immune systems. Like E. coli, it can contaminate wells through fecal matter.
   
   
4. Campylobacter: This bacterium is one of the most common causes of bacterial diarrhea in the developed world. Private wells are susceptible to campylobacter contamination, particularly those with septic system leaks or agricultural runoff. Thousands of shallow-dug surfaced wells operate in the Fraser Valley, yet many have not been tested.
   
   
5. Vibrio cholerae: Although less common in places like British Columbia, Vibrio cholerae, the bacterium responsible for cholera, is indeed found in well water under certain conditions.
   
   This bacterium typically thrives in warm, brackish water and can enter well water through various pathways.
   
   The most common route of entry is through contaminated surface water infiltrating shallow or poorly protected wells.
   
   This contamination can occur due to inadequate sanitation, where sewage or runoff containing the bacteria seeps into the groundwater.
   
   The risk of such contamination increases significantly in areas prone to flooding or those with high water tables.

Beware of FREE Water Testing in the Fraser Valley

Numerous companies in the Fraser Valley have promoted “free” water testing as a tactic to sell their costly water treatment systems. Here’s how it typically unfolds: a salesperson, under the guise of a treatment specialist, visits your home to conduct “tests” using color-changing strips available for $10, offering the same inferior results. However, this comes with the added inconvenience of dealing with a persistent salesperson in your kitchen.

Treat your water samples with caution, as they generally need to be analyzed by a certified laboratory, not by a salesperson at your doorstep offering tests with a kit. Buyer beware…

It’s also important for Fraser Valley well owners to be aware of local Fraser Health advisories and water quality reports, which can provide specific information about regional water safety concerns.

Summary: Article References and Studies

How can the presence of bacteria in tap water be detected?

Standard water tests detect the presence of bacteria in water to assess its quality. These tests check for coliforms and other pathogens to ensure the water is safe for consumption.

 Important: If bacteria is present in your water 

Bacteria in drinking water indicates contamination from possible sources like septic systems, agricultural runoff, or natural deposits. Such contamination is a serious health hazard. Potentially causing waterborne diseases varying from gastrointestinal problems to more severe illnesses, depending on the bacteria or pathogens involved.

What is the incubation period for illness caused by waterborne bacteria?

The incubation period for waterborne bacterial enteric infections varies depending on the specific bacteria. Studies have reported the following for some waterborne diseases:

 

• • Cryptosporidium Infection: During the 1993 Milwaukee outbreak, strong associations between drinking water turbidity and emergency room visits related to gastroenteritis and hospital admissions among the elderly were observed at lags of 5–6 days consistent with the Cryptosporidium incubation period.
    
    A second peak of illness among the elderly occurred at 13 days, accounting for about 40% of all excess cases among the elderly, suggesting a shorter Cryptosporidium incubation period and high risk for person-to-person transmission (Naumova et al., 2003).

• • Listeriosis: A brief for the incubation period of listeriosis, an illness that may be waterborne, noted that the incubation period significantly differs by clinical form of the disease. The overall median incubation period was 8 days (range: 1–67 days); longer periods were observed among pregnancy-associated cases (median: 27.5 days; range: 17–67 days) compared with central nervous system cases (median: 9 days; range: 1–14 days) and bacteremia cases (median: 2 days; range: 1–12 days) (Goulet et al., 2013).

• • E. coli Infection: An outbreak of E. coli O157:H7 associated with a contaminated water supply had a significantly shorter incubation period median than had been previously reported, 3-4 days, potentially due to the high dose of ingested bacteria (Johnsen et al., 2010).

• • Norwalk-like Virus: Outbreaks of clinically and epidemiologically confirmed Norwalk-like virus infection (acute gastroenteritis) were defined as those in which illness lasted less than 3 days; no fever or signs or symptoms of disease other than diarrhea and vomiting preceded illness; no bacterial pathogen was identified in association with the outbreak; and the pattern of illness was characterized by a mean (or median) incubation of 24-48 hours (Kaplan et al., 1982).

These studies reflect the range among illnesses caused by different waterborne pathogens; their incubation periods may be as short as 24 hours to several weeks.

It is important, therefore, to determine the specific pathogen causing an outbreak so that the risk can be understood and appropriate public health measures can be implemented.

Will bathing in water with coliform bacteria lead to infections?

Engaging in water sports or swimming in areas in the Fraser Valley contaminated with coliform bacteria, such as some strains of E. coli that are antibiotic-resistant, could come with a risk to your well-being.

These bacteria have been found to cause infections, and have been shown to heighten the risk of infection when they’re resistant.

One study, for instance, underscored the danger of having recreational water activities, such as spearfishing, near wastewater treatment plants with antibiotic-resistant E. coli.

This was just one of several to suggest there are potential public health risks to swimming in polluted waters, in addition to a survey called the Beach Bum Survey that noted that surfers were frequently exposed to antibiotic-resistant E. coli.

The global issue of antibiotic-resistant bacteria in bathing waters is a serious one, with implications for anyone who enjoys water-based activities. 

These bacteria can be ingested, and may be resistant to critical third-generation cephalosporins, an important tool used to treat a number of infections. These results underscore the critical need for regular water quality testing at recreational sites and the importance of controlling coliform and antibiotic-resistant bacteria.

Bathing waters must be held to the strictest safety standards, in order to ensure that swimmers and anyone taking part in water activities remain safe and healthy.

Latest findings on bacteria levels in private water well systems

Research on bacteria levels in private water well systems, not just specific to the Fraser Valley or British Columbia, emphasizes the necessity of consistent testing and acknowledges the potential for contamination from various sources, such as septic failures and surface water intrusion. Here are some notable insights:

 

• • Regular Sampling: Critical for detecting and monitoring Escherichia coli, which shows variation across different geographical locations and seasons.

    The detection rate of E. coli increases with more frequent sampling, indicating the need for stricter testing frequency guidelines (Latchmore et al., 2020).

• • Enteric Viruses: Sporadically found in groundwater from private wells in rural areas, albeit infrequently. This finding questions the reliability of using fecal bacteria as indicators for viral contamination (Pang et al., 2021).

• • Variability in Contamination: Research in Ontario wells reveals differences in fecal sources and pathogen levels, with septic tank density and geological factors offering explanations for regional contamination differences.

    A small percentage of samples were contaminated with enteric pathogens, with E. coli qPCR measurements correlating strongly with Bacteroides markers (Felleiter et al., 2020).

• • Opportunistic Pathogens: Legionella and mycobacteria were found ubiquitously in private well water, highlighting the potential health risks from inadequately maintained private water systems.

    Further investigation is recommended to fully understand these health implications (Xue et al., 2020).

• • Shiga Toxin-Producing E. coli (STEC) Risks: The importance of monitoring groundwater sources for STEC presence is underscored to prevent waterborne disease outbreaks (Reynolds et al., 2020).
