IMPORTANT NOTICE: ELEVATED LEAD WATER SAMPLE RESULT(S)
Havenwood Preschool Center
ELEVATED LEAD WATER SAMPLE RESULT(S)
All Maryland public and nonpublic schools are required to sample all drinking water outlets for the presence of lead pursuant to the Code of Maryland Regulations. On November 10th,2021),5 lead water samples were collected from [Havenwood Preschool Center Of these lead water samples, 3 had levels of lead exceeding the State’s revised action level of 5 parts per billion (ppb) (formerly 20 ppb; 5 ppb effective June 1, 2021) for lead in drinking water in school buildings. The elevated lead results from the sample(s) collected at Havenwood Preschool Center were as follows:
5.84 parts per billion (ppb) sink in library/teachers conference room for handwashing for staff only
12.3 parts per billion (ppb) water fountain in Fellowship Hall – this fountain was rarely used by preschool students
12.5 parts per billion (ppb) church kitchen sink- this sink is never used by the preschool only by the church
*** the water fountains that the children get their drinking water from both tested at less than 2 parts per billion.
ACTION LEVEL (AL)
Effective June 1, 2021, the State’s AL for lead in drinking water samples collected from outlets in school buildings has been lowered to 5 ppb. The AL is the concentration of lead which, if exceeded, triggers required remediation of drinking water outlets.
HEALTH EFFECTS OF LEAD
Lead can cause serious health problems if too much enters your body from drinking water or other sources. It can cause damage to the brain and kidneys, and can interfere with the production of red blood cells that carry oxygen to all parts of your body. The greatest risk of lead exposure is to infants, young children, and pregnant women. Lead is stored in the bones and it can be released later in life. During pregnancy, the fetus receives lead from the mother’s bones, which may affect brain development. Scientists have linked the effects of lead on the brain with lowered IQ in children. Adults with kidney problems and high blood pressure can be affected by low levels of lead more than healthy adults.
SOURCES OF HUMAN EXPOSURE TO LEAD
There are many different sources of human exposure to lead. These sources include: lead-based paint, lead-contaminated dust or soil, some plumbing materials, certain types of pottery, pewter, brass fixtures, food, and cosmetics, exposure in the workplace and exposure from certain hobbies, brass faucets, fittings, and valves. According to the Environmental Protection Agency (EPA), 10 to 20 percent of a person’s potential exposure to lead may come from drinking water, while for an infant consuming formula mixed with lead-containing water this may increase to 40 to 60 percent.
IMMEDIATE ACTIONS TAKEN
Signs were posted by all areas with exceeded lead testing that they were closed/ no drinking from any of these faucets.
On February 21st, the water will turned off to the building and water filtration systems will be added to the piping connections of the effected units. Water samples will again be collected and sent to the lab to acquire new results. All areas will remained closed until those results are returned and proven to be under the 5 parts per billion threshold.
TO REDUCE EXPOSURE TO LEAD IN DRINKING WATER:
- Run your water to flush out lead: If water hasn’t been used for several hours, run water for 15 to 30 seconds or until it becomes cold or reaches a steady temperature before using it for drinking or cooking.
- Use cold water for cooking and preparing baby formula: Lead from the plumbing dissolves more easily into hot water.
Please note that boiling the water will not reduce lead levels.

If you are concerned about exposure; contact your local health department or healthcare provider to find out how you can get your child tested for lead.
