Dangerous Lead in Minnesota Schools

Kids at Risk: Minnesota Schools Failing to Follow Guidelines on Testing for Lead in Water

September 08, 2016 11:17 AM

School officials across Minnesota are knowingly putting thousands of children at serious risk by not following guidelines on testing for lead in water and not fixing water systems that they know are defective, a 5 EYEWITNESS NEWS investigation has found.

Our news staff poured over the water testing records of more than 600 Minnesota schools and found at least one out of every four of those schools are not following the state’s recommendations that a school be tested at least once every five years. We found some schools that have not been tested for lead since the late 1990s.

When looking at the reports in the map embedded below, keep in mind the Minnesota Department of Health’s guideline for schools: If lead is at or below 20 parts per billion (ppb), the tap may be used for drinking water or food preparation. If lead exceeds 20 ppb, twice daily flushing should be done.

School districts are not on the hook for exposing children to increased health risks by having high amounts of lead in water, 5 EYEWITNESS NEWS found: The Minnesota Department of Health only recommends that schools test each tap or fixture providing water at least every five years.

And, it appears the department is lax when it comes to its oversight of monitoring schools that have gone long periods of not testing water. For example, records show Minneapolis Public Schools has not tested at least 31 of its schools since 1998. A district alternative school for pregnant and parenting students – Longfellow School – was last tested for lead amounts in 1998, according to district records.

“It’s a little surprising to me to hear that there are systems that have not been tested for very long periods of time,” Assistant Commissioner of Health Paul Allwood said. “I should point out that our guidelines are voluntary,” Allwood added. “That’s what we’re discussing – should there be additional authority.”

Document: MDH Guidance on Reducing Lead in Drinking Water

Minnesota communities that receive municipal water already test for lead in the system but health officials suggest schools test due to possible lead solder, brass fixtures, water usage and age of materials that could be in the water system students could drink from.

Dr. Marc Edwards, the nation’s leading authority on lead amounts in water, said in an interview that lead amounts of more than 20 parts per billion (ppb) is a critical health concern. Edwards is a professor at the Virginia Tech University and led the outcry over the recent contaminated water crisis in Flint, Michigan.

KSTP reporter Eric Chaloux went to Edwards’ lab on campus on in Blacksburg, Virginia, to learn more.

“Parents really need to hold schools’ feet to the fire to make sure this problem is fixed,” Edwards said. It costs as little as $30 to fix the problem when it comes to water fountains and high amounts of lead coming out of them, he said.

The American Academy of Pediatrics recently stated school water fountains should not exceed water lead concentrations of more than 1 ppb.

In our records review, news reporters and producers found that school children from Burnsville, Savage and Eagan – District 191 – were exposed to lead levels up to 942 ppb from one drinking fountain tested in 2013. That amount ranks as one of highest contaminant levels detected in the records reviewed. That fountain is at Joseph Nicollet Junior High School in Burnsville.

“One drink from that fountain, that’s a health concern,” Edwards said when he reviewed those specific results.

What is in your water?

FREE Water Testing !
There could be many things lurking in your water that you do not know about. Call Minnesota Water today for a FREE total dissolved solids (TDS) water testing.

TDS affects everything that consumes, lives in or uses water, from fish and planets to plumbing and laboratories.

For people, the lower the TDS level in the water you drink, the more efficiently your body’s cells are hydrated. The higher the TDS level in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water in the body.

Why Should You Measure the TDS Level in Your Water?
The EPA Secondary Regulations advise a maximum contamination level (MCL) of 500mg/liter (500 parts per million (ppm)) for TDS. Numerous water supplies exceed this level. When TDS levels exceed 1000mg/L it is generally considered unfit for human consumption. A high level of TDS is an indicator of potential concerns, and warrants further investigation. Most often, high levels of TDS are caused by the presence of potassium, chlorides and sodium. These ions have little or no short-term effects, but toxic ions (lead arsenic, cadmium, nitrate and others) may also be dissolved in the water.
Even the best water purification systems on the market require monitoring for TDS to ensure the filters and/or membranes are effectively removing unwanted particles and bacteria from your water.
The following are reasons why it is helpful to constantly test for TDS:

Taste/Health
High TDS results in undesirable taste which could be salty, bitter, or metallic. It could also indicate the presence of toxic minerals. The EPA’s recommended maximum level of TDS in water is 500mg/L (500ppm).
Filter performance
Test your water to make sure the reverse osmosis or other type of water filter or water purification system has a high rejection rate and know when to change your filter (or membrane) cartridges.
Hardness (and Water Softeners)
High TDS indicates Hard water, which causes scale buildup in pipes and valves, inhibiting performance.
Aquariums/Aquaculture
A constant level of minerals is necessary for aquatic life. The water in an aquarium or tank should have the same levels of TDS and pH as the fish and reef’s original habitat.
Hydroponics
TDS is the best measurement of the nutrient concentration in a hydroponic solution.
Pools and spas
TDS levels must be monitored to prevent maintenance problems.
Commercial/Industrial
High TDS levels could impede the functions of certain applications, such as boilers and cooling towers, food and water production and more.
Colloidal silver water
TDS levels must be controlled prior to making colloidal silver.
Coffee and Food Service
For a truly great cup of coffee, proper TDS levels must be maintained.
Car Washing and Window Cleaning
Have a washer with a spotless rinse? An inline dual TDS monitor will tell you when to change the filter cartridge or RO membrane.

I met with both Steve (owner) and Nate (Sales rep) to discuss our best options for a hot/cold water cooler. Not only did we get 2 great machines, the customer service was fantastic. These guys were extremely knowledgeable, friendly, customer focused, and they delivered! The water is fantastic and it's worry free...no more loading bottles of water in the fridge everyday and in an office of 24 people that's a time saver for me! I guess the only suggestion I would have for Nate & Steve is to inform customers (and maybe they do for others) that on Mondays, when the cooler has not been used for 24 hours there is a slight after taste but once it starts getting used that immediately goes away. Love the convenience of paying quarterly as well, saves more time & money. I would definitely recommend Minnesota Water to any individual or organization.

We've had our filtered water systems for several years now and Steve has done a really great job helping us maintain them. He and his team make it truly a worry-free experience with their prompt response to maintenance and service request. Over the years as we grew and added sites in different areas of the country, Steve oversaw the installation of systems at those offices as well. There wasn't much that I had to do, which was definitely good for me being that I was hundreds of miles away. He implemented centralized billing too, so that I didn't have to fool around with multiple different invoices coming from the different servicers. All around, it's been a great experiencing working with Minnesota Water. I'm grateful!

Minnesota Water keeps both of our elder-care facilities perfectly hydrated and well served! We are so grateful for Steve and his team and the way they have handled our unique needs. We did extensive research trying to balance cost and quality, and Minnesota Water came out the clear winner. In all cases, when we have needed immediate service, we are treated like royalty--our seniors love the ease and convenience and taste of the water. I wouldn't go anywhere else for water--and how relieving it is that Steve has heart for his customers and will go the extra distance because he truly cares!
