Getting the lead out of drinking water - one fixture at a time

National Lead Poisoning Prevention Week is October 22-28, 2023

Certified Water Professionals across the state are our front line for promotion of the Culture of Health in drinking water. They work hard to protect water consumers at public water systems from all kinds of contaminants, from bacteria to uranium. One of the most complicated rules for protecting water consumers is the Lead and Copper Rule (LCR). Even when this rule is fully-implemented, it relies on careful sampling at a representative number of sample sites. No public water system is required to test at every point where consumers drink water to see if lead is present. 

But there is another program in Colorado that is doing just that. In 2022, the state legislature wanted to make sure that Colorado’s children were protected from lead in drinking and cooking water sources in the locations where they spend most of their time away from home: child care facilities and schools. The legislature passed House Bill 22-1358, implemented by the Water Quality Control Division as the Test & Fix Water for Kids program. This program, launched during the 2022-2023 school year, has conducted outreach to the nearly 6,000 licensed child care facilities and public or facility schools across the state serving children fifth grade and under. Each facility was asked to identify every water fixture used for drinking or cooking, and they were provided free test kits and analyses for lead. Over the past year, the program analyzed lead at over 53,000 fixtures across the state, representing about 600,000 children at 4,700 licensed facilities and schools. Ninety three percent (93%) of the samples collected were below the program action level of five parts per billion, and the remainder, about 3,700 fixtures total, are working through remediation funded by the program.

Why focus on fixtures?

In most cases, older brass fixtures are the cause of lead in water at schools and child care facilities. Older fixtures are not certified as lead free, and the materials in the fixture, when in contact with water, can leach lead. Replacing these fixtures can be a good solution. While lead service lines or copper pipe with lead solder can also be a source of lead, testing elevated locations with a follow up flush sample can help determine if premise plumbing is a cause. Almost none of the over 3,000 flush samples collected in this program showed elevated lead due to water contact with premise plumbing, and lead service lines were not commonly used for non-residential buildings. After repairs are made, each location is retested to confirm that lead is not present. The program is expanding to middle schools in the 2023-2024 school year.

How does this program affect compliance for public water systems with the LCR? 

The short answer is, it doesn’t! The results from this program are not reportable as part of the LCR and sampling conducted as part of this program do not “count” for sampling under the LCR. The good news is that when water systems do sample at these facilities, the Test & Fix Water for Kids program has already worked to get the lead out - one fixture at a time!

What can I do to protect myself and my family from lead in drinking water?

  • Before drinking, run the tap for 30 seconds.
  • Use only COLD water for drinking, cooking, and making baby formula. Boiling water does NOT remove lead.
  • Regularly clean the aerators on your faucets.
  • If you use a filter to remove lead, maintain it regularly.

Equipping Operators with Skills to Manage and Overcome Testing Anxiety

In the Summer of 2021, this article was originally published in the Arkansas Department of Health’s Drinking Water Newsletter.

We have all experienced it, that feeling of dread and foreboding before taking an exam; a myriad of scenarios running through your head outlining the worst possible outcomes.

These feelings of testing anxiety are very real and can have detrimental effects on an operator’s exam performance. In fact, a recent survey of operators conducted by the Ohio Water Environment Association found that nearly 30 percent of respondents cited testing anxiety as a main cause for not passing the exam.

To examine why testing anxiety is such a prevalent phenomenon, especially in high stakes vocational testing such as an operator certification exam, I spoke with Dr. Ian MacFarlane of Elizabethtown College. Dr. MacFarlane is an Assistant Professor of Psychology, as well as a clinical psychologist. With more than 1,000 hours of therapy work with college students and adults, he has helped countless individuals recognize and overcome testing anxiety.

Why do Operators worry?

Taking a certification exam is different from a high school biology or chemistry final: the stakes are exponentially higher. Psychologically, operators may feel that taking an exam related to their everyday job duties raises a question about their professional competence. This spark of anxiety will be fanned further if a passing score on the exam is mandated for their current job or required for promotion potential.

When asked how test anxiety manifests, Dr. MacFarlane pointed to both cognitive and physical (or somatic) symptoms stating, “The most detrimental effects of anxiety are cognitive. The human brain is limited to a certain amount of processing power at one time. The more your brain is occupied with the anxiety of the exam, the less ability it has to process the exam content. It would be akin to going into a wrestling match with one hand tied behind your back. Anxiety is a ‘mental suck’ or leech draining your brain power and limiting your ability to recall information or facts that might be as familiar to you as the names of your parents.”

One particularly common manifestation of testing anxiety Dr. MacFarlane cited is detachment–an operator is likely to avoid the discomfort of test anxiety by simply not thinking about the exam. Just as your body will pass out instead of coping with a lack of oxygen, you are likely to avoid the discomfort of test anxiety by simply not thinking about the exam.  He noted, “This can be quite detrimental as this avoidance loop can cause you to disengage from exam preparatory practices which can seriously hinder performance on the exam.”

Other effects of anxiety can be seen as physiological symptoms such as nausea, stomach cramps, or lightheadedness. To explain this, Dr. MacFarlane offered, “Our bodies lack the ability to differentiate between real life and mental simulations. So, if we are extremely worried or anxious about something, our minds can create physiological manifestations that are directly associated with the negative mental simulations.”

Why do some operators who excel in their jobs perform poorly on the exam?

Even though the exam is measuring the knowledge and application of tasks that an operator performs daily, while in the testing environment, they lose the contextual cues that would normally assist them in everyday operations.

Without those additional sources of information, operators must work harder to draw parallels between the tasks on the exam and the tasks they perform in their job. In other words, because an operator is not being tested in the environment in which he/she normally performs a task (a water or wastewater system), it can be difficult to recognize and solve the same problem in a test environment.

What can operators do to help with testing anxiety?

Practice, Practice, Practice

There is no better way of reducing test anxiety than to spend an adequate amount of time preparing and practicing. Test-taking is a skill—one that must be practiced and honed. Dr. MacFarlane noted that in many cases, due to inefficient study techniques, people have a tendency to work on areas in which they are already proficient and to avoid areas that could use improvement. Operators should make better use of their study time by taking periodic practice tests to help gauge the areas they need to work on. As an added benefit, the practice tests will train them to work under the pressure of a time constraint. Because the time limit on most certification exams can create a state of panic, it is important that operators learn to perform under these stressors and to control the feelings of unease.

Don’t “cram”

Countless studies have been done over the years on the ineffectiveness of “cramming,” or waiting until the last available opportunity to study for an exam. Say an operator spends the last six hours before the exam reviewing material. It is easy for them to think that they have everything committed to memory; the material is “fresh” in their mind. The reality is that nothing could be further from the truth. Reviewing this way gives an operator a familiarity with the material, meaning he/she will be able to recognize it when they see it on paper. Unfortunately, the ability to recognize concepts is not the same as being able to recall it. The ability to recall or reconstruct information accurately when an operator needs it requires exposure to the information over a long period of time.

The best course of action is to build a study plan that spans the course of several weeks prior to the exam. The more time an operator spends reorganizing the material so it has a structure, the more likely they are to commit the information to long term memory. Operators should aim for 45-60 minutes per day with their study material for at least six weeks prior to the exam.

How can an operator cope with anxiety on test day?

Even the most prepared test-takers can feel anxiety on test day, but there are proven methods to counteract the effects. Operators should start with getting adequate sleep the night before. Studies have shown that people perform better on memory tasks when they are well-rested. Some people will suffer from interrupted sleep when particularly worried about something. To help with this, operators can try exercising for 30 minutes before bed. Doing so will help their bodies release excess cortisol (stress hormone) in their systems caused by anxiety and will allow them to sleep better.

An operator should ensure their body is well nourished the day of the exam. This means do not skip breakfast and eat healthy foods such as grains or fruit and avoid foods with high fat content. The goal here is to eliminate as many distractors as possible so an operator can dedicate all their attention to the exam. If an operator is tired or his/her body does not have enough fuel, it can drastically hinder their performance.

Breathing – The 5-5-7 Method

During the exam, it can be extremely beneficial to stop at regular intervals (perhaps every five questions) and take deep breaths. The 5-5-7 is a breathing exercise performed by inhaling for five seconds, holding your breath for another five seconds, then exhaling for seven seconds. Dr. MacFarlane suggested that completing this exercise at regular intervals during a test session can physiologically stimulate the central nervous system, which can heighten an operator’s awareness and push anxiety from their mind. He also stressed the importance of practicing this technique for several weeks prior to the exam during their preparation, saying “The more practiced you are in this technique, the more effective it will be during exam time. Your body and mind will have a Pavlovian response to the exercise which increases its effectiveness.”

Muscle Relaxation

Another proven technique outlined during our discussion was progressive muscle relaxation, or PMR. This is done by deliberately applying tension (by clenching) to certain muscle groups and then releasing the induced tension. During this process, all of an operator’s attention should be focused on how their muscles feel as the tension is released. As operators learn to distinguish the feelings of a tense muscle as compared to a completely relaxed one, they are able to recognize the physical effects anxiety has on their bodies and can quickly alleviate it with this technique. Operators should be encouraged to practice PMR both when preparing for the exam and on the day of testing. They should spend 15-20 minutes at a time performing this technique on their major muscle groups (feet, legs, hands, arms, neck, and shoulders) and it will help mitigate anxiety.

The Bottom Line

While these methods have been shown to help with anxiety, they may not work for everyone. There are many more techniques that may offer relief, and operators can use these tips as a starting point to find what works best for them. Above all, operators should make sure they spend adequate time studying and reviewing the material. The better command they have of the content, the less anxious they will be about the exam, and the better they will perform.

Ready, set, go - the WQCD provides assistance for lead service line projects

On December 16, 2021, EPA finalized the Lead and Copper Rule Revisions (LCRR), which further strengthened the protections against lead in drinking water. The LCRR requires community and non-transient, non-community public water systems to develop a service line inventory (LSLI) to identify the materials of service lines connected to the public water distribution system. If one or more lead, galvanized requiring replacement, or lead status unknown service lines are identified, systems must submit a lead service line replacement (LSLR) plan. Both documents are due to the Drinking Water Compliance Assurance Section by October 16, 2024.

The Water Quality Control Division (division) is providing free technical assistance and grants to help eligible public water systems with the service line inventory and lead service line replacement planning process. Additionally, there are low interest loans available for lead service line removal construction costs.

Direct Technical Assistance

Through a competitive bid process, the division has selected WSP, in partnership with Sunrise Engineering, to support water systems serving up to 15,000 persons. Suppliers can request remote support or hands-on assistance, offered at no cost until funding is depleted. The division has selected only one contractor to provide no-cost technical assistance and support to eligible water systems, and under this assistance program it will not reimburse systems for the costs of hiring outside contractors. Suppliers can sign up here to be contacted by WSP. 

Technical Assistance Grants

The division has additionally made grant funding available to assist public water systems with the service line inventory and lead service line replacement planning process for those systems who elect to perform work outside of the technical assistance program above. Grants range from $10,000 to $250,000, and cover 90% of the project cost. Applications will be accepted at four upcoming deadlines, beginning October 1, 2023. Grants will be awarded on a first-come, first- served basis during each application review period, until funds are depleted. Reimbursements will only be made for expenses incurred after the grant agreement is executed. Smaller water systems are encouraged to make use of the technical assistance provider before applying for grant funding. 

Eligible applicants for the grant program include:

  • Publicly owned water systems and private not-for-profit public water systems whose service area is between 7,500 persons and 50,000 persons and whose Median Household Income is less than 120% of the State’s Median Household Income.
  • Publicly owned water systems and private not-for-profit public water systems whose service area is larger than 50,000 persons, and whose Median Household Income is less than 80% of the State’s Median Household Income.
  • Applicants must proceed with work within 30 calendar days of contracting.
