In the twenty years that we have been in business, we have seen very few changes for the better in terms of water quality. In fact, there are more things to worry about now than there were in 1989 when Lakota Scientific, Inc. was started. The basic fact remains the same; it is up to you to make sure that the drinking water for your family is clean and say nothing of just simply tasting better.

Pharmaceuticals:  Minute quantities of prescription drugs that have been flushed into the rivers and surface water and that eventually make their way to the tap is now knows to be a valid concern just about everywhere in the U.S.

Hydraulic fracturing: Sixty percent of all natural gas wells in the U.S. use hydraulic fracturing, which require millions of gallons of toxic chemicals to be injected into the ground in order to facilitate bringing the gas to the wellhead. This is seen by many to be a serious threat to public water systems, especially in the Midwest and for the people of New York.

Agricultural chemicals:  We read more and more about atrazine these days with the new studies that have been released, but there are many more examples of herbicides, pesticides and chemical fertilizers that find their way into public water supplies and private wells.

Arsenic: New studies are showing that naturally occurring arsenic is a problem for many water supplies and wells all across the U.S. because it is being linked to a wide range of health concerns including cancer. As a consequence, the maximum allowable contaminant level (MCL) has been lowered from 50 parts per billion (ppb) to 10 ppb.

Perchlorate: Improper disposal of huge amounts of perchlorate, a component of jet fuel, is thought to have contributed greatly to this problem which is known to be widespread. Enforcement is lax, and the EPA is failing to address the recommended standard of 1 ppb, down from 15 ppb. This is a serious concern for developing children and pregnant women that a good carbon block water filter can address.

The usual culprits: Low molecular weight solvents, such as trichloroethylene; disinfection byproducts, such as trihalomethanes; high molecular weight contaminants, such as pesticides; heavy metals, such as lead, vanadium, chromium, uranium, and. of course, disinfectants such as chlorine.
