The Ecology Center Turns a Local Scare Into Statewide Change
This story is part of the Michigan Environmental Council's 2022 member magazine, "ECOsystems: Working Wonders With Water." You can read the magazine in full here.
The Ecology Center knows lead poisoning well. For 50 years, the Environmental Council member group has connected the dots between our health and our environment by eliminating dangerous substances that infiltrate our daily lives.
But the work became worryingly personal for Rebecca Meuninck, its deputy director, when lead was found in the drinking water of Ann Arbor School District. Her son went there.
Since then, Meuninck and the Ecology Center have become key leaders in the effort to eliminate the threat of lead in school drinking water in Ann Arbor and across the state.
The effort has been dubbed “Filter First,” and a coalition of 40 groups and individuals is driving it. Since 2019, it’s sought to get filtered drinking water stations installed in every school and childcare center in Michigan, virtually eliminating lead’s threat.
Thanks in part to Meuninck and the coalition, some $50 million of the state’s budget has been earmarked for the cause, and widely bipartisan legislation that would activate those funds is poised to pass in the coming months. If the bills become law, they could set the rest of the nation in motion.
“I’m hopeful that we can get it pushed through in Michigan, and we’re certainly going to share it with our friends in Ohio and other places throughout the Great Lakes,” Meuninck said. “We want to make sure kids all over the country are protected.”
FROM CRISIS TO ACTION
Filter First and its formula for success arguably stems from Ecology Center’s expertise and the lead poisoning dilemma Meuninck faced.
It was the wake of the Flint Water Crisis. School districts like Ann Arbor’s began to test their water for lead and found high levels of it in many of their buildings. This was scary news for the school district’s 17,000 students.
Lead poisoning lowers IQ and raises hyperactivity, making it difficult for children to learn in school and find financial success as adults. Lead also reduces impulse control, leaving those suffering prone to delinquency. And lead’s effects can surface far later in life, like through Parkinson’s disease and osteoporosis.
In effect, the schools meant to set children up for success were simultaneously, unknowingly hindering them. And Ann Arbor was not alone. Of the 114 Michigan schools and childcare facilities that voluntarily submitted water testing data to the state, 71% had lead levels above the legal filtered limit. No amount is safe.
Ann Arbor School District officials and concerned parents like Meuninck acted. They utilized a sinking fund and donations to test pipes for lead and fix those that had the toxic metal. But the nature of schools meant lead kept coming back, said Meuninck.
At home, water always circulates. We brush our teeth, drink water, and flush toilets. At schools, there are always breaks in circulation—on the weekends, over holidays, through the summer. During those breaks, water sits stagnant, wearing off chemicals that keep lead at bay.
Compounding the issue was the average age of most Ann Arbor schools: 65 years. That’s well before lead was banned in most products. The same scenario plays out in hundreds of districts across Michigan: old schools, bad water circulation.
So, with parents like Meuninck assisting, the school district pivoted and installed lead filters on drinking water stations. These took much less money and time to install and maintain, and they were just as effective at eliminating lead. The district also kept the installation, maintenance, and test results of water transparent to the public.
The results were immediate. Lead levels dropped to nonexistence, and time will soon show the positive impact that has had on students’ grades, behavior, and energy.

5 Simple Tips How To Choose Hydraulic Filter
First, consider the type of fluid you will be filtering. Different fluids require different types of filtration, so it's important to make sure your filter is compatible with the fluid in question.
Next, think about the operating conditions and environment in which your filter will be used - this can affect both the type and size of filter needed. Finally, consider the efficiency and pressure drop requirements for your application.
By taking all of these factors into consideration, you'll be able to choose the right hydraulic filter for your business and keep it running smoothly. Happy filtering!
Another tip to consider is the compatibility of the filter with your hydraulic system. Make sure to check that the filter will fit properly and won't cause any issues with your equipment.

Implement the following functions:
a) filterFirst :: (a -> Bool) -> [a] -> [a]
so that filterFirst p xs removes the first element of xs which does not
satisfy the property p. For instance,
filterFirst even [1,2,3,4] ~~> [2,3,4]
b) filterLast :: (a -> Bool) -> [a] -> [a]
so that filterLast p xs removes the last element of xs which does not
satisfy the property p. For…

Some Precautions You Should Know When Wearing Chemical Gas Filter
The chemical gas filter, in other words, can also be called respirator. In many chemical industries, many jobs need to be equipped with chemical gas filters, which can play a very good protective role in these working environments.
Chemical gas filter is a kind of labor protection product that protects the safety of human breathing. The gas mask is used to closely fit the human face, thereby effectively isolating the toxic environment from contact with the human respiratory system. Gas masks are used in a wide range of fields. Chemical gas filters are suitable for coal mining, grinding, mining, metal smelting, chemical and other industries. This blog will introduce the precautions for using chemical gas filters from three aspects.
Precautions before using chemical gas filter
First of all, before the user wears the chemical gas filter, he must first understand the gas content in the working environment, especially the concentration and nature of the toxic gas, which is a very important prerequisite. Because the concentration of toxic gases in the air has a specified range, in different ranges, it is recommended to use different types of gas masks. Secondly, before use, you must carefully check whether the various parts of the gas mask are intact, whether the air duct is unblocked, whether the metal parts are rusted, whether the rubber is aging or damaged, and also check the buckle of the fixed canister in the mask bag. Whether there is a problem with the belt, etc. Again, carefully check the airtightness of the joints between the components before use. Finally, according to the user's personal situation, choose a mask of the right size.
Precautions while using chemical gas filter
The core component of the chemical gas filter is the canister. The canister plays a key role in the issue of anti-virus effect. Therefore, it is recommended that users strictly observe the effective time of the canister. Here, we provide you with some methods for judging when the canister should be replaced: the first case: when the user wears the filter-type gas mask, he can still smell some toxic gas; the second case: If you feel that the resistance of the filter tank is too small, it means that the anti-virus effect has basically failed; the third case: if the user shakes the canister by hand, he can hear the sound of rustling, indicating that there is a problem with the assembly and the canister needs to be replaced in time. In addition, during the use of the gas mask, it is forbidden to open the lid of the canister at will, and to prevent liquids from flowing into the canister.
Precautions after using chemical gas filter
After the protective mask is used, it must be cleaned and disinfected in a timely manner. It is forbidden to use gasoline, organic solvents, etc. to clean the mask. Corresponding systems and regulations must be formulated to ensure that special personnel are in charge and the responsibilities are assigned to each person.
Protection ourselves is an extremely important thing. So high quality and high standards mask is needed. If you want to find oem chemical gas filter manufacturer, we will be your best choice. Welcome to contact us by [email protected].
