Information about water quality in Missouri City can be surprising.

But there are things you can do in your home to clean up your water.

To Remove Lead and Other Contaminants In Your Home:

There is one solution that beats Brita, PUR, and some whole house systems.

  • It costs less per gallon.
  • Needs fewer filter changes.
  • And it doesn’t make your water taste weird.

  • Use Berkey filters with activated carbon to filter out the majority of contaminants in your drinking water.
    • Berkey filters can also remove up to 99.99% of Lead in Missouri City water.
    • Brita can filter 28 contaminants and Lead depending on the filter.
    • Note: We may receive a commission if you decide to purchase filters through links on this page.
  • To filter out 46 of the 49 contaminants, consider a Reverse Osmosis water filtration system for your house.

*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.

In Your Community:

Contact your local government officials and put pressure on them to invest in cleaner waterways and upgraded city water filtration and treatment.
