In April 2024, the Environmental Protection Agency (EPA) announced the first-ever national, legally enforceable drinking water standards for per- and poly-fluoroalkyl (PFAS) substances. Known as “forever chemicals,” PFAS poses significant risks to public health. Studies have shown links between PFAS and liver damage, thyroid disease, immune system changes, developmental effects or delays in infants and children, higher rates of certain cancers and higher cholesterol levels. The clock has started for water districts to act and protect public health by providing safe, clean drinking water that abides by the new enforceable PFAS limits. 

The New PFAS Limits

Restrictions have been imposed for five individual PFAS: PFOA, PFOS, PFNA, PFHxS and HFPO-DA (also known as “GenX Chemicals.”) There are also rule limits for mixtures of any two or more of four types of PFAS: PFNA, PFHxS, PFBS and “GenX Chemicals.” See the chart below for specific level requirements. The enforceable limits are represented by Maximum Contaminant Levels (MCLs), while the Maximum Contaminant Level Goals (MCLGs) are health-based and non-enforceable.

The Timeline for Testing and Treatment

All public water systems must complete initial testing for PFAS chemicals by 2027, followed by ongoing compliance monitoring. Beginning in 2027, public, regulated water districts are responsible for informing the public of the levels of PFAS measured in their drinking water on an ongoing basis.

If testing finds PFAS levels that exceed the legally required standards, the water district must notify the public and act to reduce the levels of PFAS in the drinking water by 2029.

How You Can Test for PFAS and Get Compliant

Technological developments such as granular activated carbon, reverse osmosis and ion exchange systems can filter PFAS appropriately. The EPA has allocated $1 billion to help water districts resolve PFAS in the drinking water, and districts have the flexibility to determine the best solution for their community.

While this all may sound overwhelming, RK Water is ready to support you through the entire process. We can:

– Perform initial PFAS sampling and testing.

In the modern world, access to safe and clean water is fundamental to public health and overall well-being. In the early 1900’s, Chlorination emerged as a water treatment process that revolutionized how we purify and disinfect water on a large scale. The impact of chlorination on society has been profound, drastically reducing waterborne diseases and saving countless lives. In this blog, we will dive into the science behind chlorination, understanding how this ubiquitous disinfection method works to safeguard our water supply.

The Need for Water Treatment

Before the advent of water treatment, communities were plagued by waterborne illnesses such as cholera, E.coli, typhoid and dysentery. These illnesses could and did spread rapidly, devastating entire populations. To address these public health concerns, two pioneering individuals developed the first water treatment plant to establish the delivery of safe drinking water to homes and businesses.

Chlorination is a Game-Changing Discovery

In 1908, a monumental breakthrough occurred when bacteriologist John L. Leal and engineer George W. Fuller introduced the practice of chlorination at the Jersey City Water Supply Company’s Boonton Reservoir in Jersey City, New Jersey, in the first large-scale chlorination of a public drinking water supply in the United States. Initially met with opposition from city officials and the public based on adding “poisonous” chemicals to the drinking water supply, Leal and Fuller persisted, convinced of the potential benefits to the public.

This marked the beginning of an era that would significantly alter the landscape of water purification and serves today as the basis for water treatment purification. By the 1920s, chlorination was a well-established primary means of disinfecting drinking water nationwide.

Today, millions of Americans have access to safe, affordable and abundant drinking water filtered and safely treated with chemical disinfectants due to Leal’s and Fuller’s pioneering engineering triumph.

Mechanism of Chlorination

Chlorination involves the addition of chlorine, either in the form of chlorine gas, sodium hypochlorite (liquid bleach), or calcium hypochlorite (solid granules), to water sources. Upon introduction, the chlorine reacts with various organic and inorganic substances in the water.

Formation of Hypochlorous Acid (HOCl):

Chlorine gas reacts with water (H2O) to form hypochlorous acid (HOCl) and hydrochloric acid (HCl). Hypochlorous acid is the active and most effective form of chlorine for disinfection.

Cl2 + H2O → HOCl + HCl

Disinfection Process:

Hypochlorous acid acts as a powerful disinfectant, attacking and destroying harmful microorganisms by penetrating their cell walls and interfering with enzymatic processes essential for survival. This disrupts the microorganisms’ ability to reproduce and spread, effectively neutralizing the threat of waterborne pathogens.

Chlorine Residual:

Maintaining a chlorine residual in the treated water is crucial to ensure continuous disinfection throughout the distribution system. A chlorine residual refers to the small amount of chlorine that remains in the water after the initial treatment. This residual concentration is a protective barrier against potential contamination during water distribution.

Challenges and Concerns

While chlorination has been a transformative and life-saving water treatment technique, some challenges and concerns are associated with its use.

Disinfection Byproducts (DBPs)

The reaction of chlorine with organic matter in water can lead to the formation of disinfection byproducts (DBPs), such as trihalomethanes (THMs) and haloacetic acids (HAAs). Some DBPs have been linked to potential health risks, including an increased risk of cancer. To address this, water treatment facilities have implemented strategies to minimize DBP formation.

Chlorine Resistance

In recent years, certain microorganisms have shown varying degrees of resistance to chlorine, making it necessary to explore alternative disinfection methods or combine chlorination with other treatment processes.


The science behind chlorination has revolutionized public health by providing access to safe and clean water on a large scale. The disinfection power of chlorine has proven pivotal in reducing waterborne diseases and preventing epidemics. Although challenges persist, ongoing research and advancements in water treatment technology will continue to refine the chlorination process, ensuring that future generations enjoy the benefits of safe and potable water.

Maintaining Safety and Efficiency

The autumn season presents unique challenges to the construction industry, but we can effectively navigate them with proactive measures and a focus on safety. By taking necessary precautions, construction sites can maintain a safe and productive environment during this beautiful time of year.

Grasping the Gravity of High Suicide Rates in the Construction Sector

Research has shown that the construction industry, which is primarily male-dominated, has one of the highest suicide rates among its workforce. Men have been conditioned by society to suppress their emotions, leading to silent suffering. The industry is well-known for its “tough-guy” persona and emphasis on self-sufficiency, appealing to those with risk-taking tendencies. Nonetheless, this culture can also pose obstacles for those seeking mental health support, warranting sensitivity and consideration.

In addition, construction schedules often require extended work hours and job relocations, resulting in feelings of detachment from loved ones. The physical demands of the job, combined with a sense of isolation, can drive individuals to self-medicate with alcohol, drugs, or opioids, further increasing the risk of suicide.

The Significance of Mental Health in the Workplace

Mental health plays a crucial role in construction sites as it directly impacts the safety and well-being of the crew. A mentally healthy workforce is not only happier but also more productive. Key indicators of mental distress include lethargy, lack of motivation, concentration difficulties or absenteeism.

Promoting mental health and wellness within the workplace can foster a positive atmosphere for employees. As a result, this can aid in retaining and recruiting staff members who are interested in pursuing a career in the construction industry.

Comprehending Mental Health

Maintaining good mental health is an ongoing process. Various factors such as personal loss, financial difficulties and relationship issues can negatively impact a person’s mental well-being and ability to concentrate. In environments with a higher risk, operating heavy equipment or getting distracted due to a lack of focus can be dangerous for both workers and the public.

Encouraging an environment where individuals feel comfortable sharing their personal experiences can empower coworkers to check on their crewmates, thereby fostering a safer workspace for everyone involved.

The Role of Management in Driving Change

As a company, it is important to prioritize the well-being of employees. Creating a sense of community and belonging can be achieved by encouraging everyone to be aware of their surroundings and environment. This is especially important in the construction industry, where transitioning from a culture of discipline to one that prioritizes employee mental health and well-being can make a significant impact.

Leaders and employees can provide essential resources to promote mental health by practicing active listening, compassion and empathy towards one another. This approach fosters a supportive environment that enables everyone to thrive.

Identifying Warning Signs on a Jobsite

When observing individuals, paying attention to their behavior and life circumstances can provide valuable insights into their mental and emotional state. Verbal expressions such as discussing suicide, depression, anxiety or feeling like a burden to others can be red flags. Some behaviors, like being absent often, experiencing a sudden decrease in productivity or engaging in risky actions, may suggest that there are underlying problems.

Additionally, personal stressors such as going through a divorce, losing a job or losing a loved one can all impact a person’s emotional well-being. Awareness of these factors can enhance our understanding and enable us to provide better support.

Implementing Measures to Manage and Prevent Workplace Suicide

Companies can play a crucial role in managing and preventing such incidents by taking proactive steps. One of the most important steps is to identify the warning signs, including changes in mood, social withdrawal, talk of wanting to die or giving away personal belongings. Creating a safe environment where employees can openly discuss their issues and feel supported is essential.

Additionally, providing access to mental health resources and safety guides can help employees deal with such issues effectively. Implementing these measures can help companies establish a safe and supportive environment, significantly decreasing the occurrence of suicide in the workplace.

Fostering a Safe Work Environment

Creating a safe and supportive work environment is vital for the well-being of employees. Encouraging open communication about mental health issues, providing access to resources and professional help, and promoting a culture of support can go a long way in achieving this goal. By taking these steps, we can help prevent suicide and save lives in the construction industry.
