Drinking Water

Summary: Water is not safe to drink if aluminum exceeds 50 µg/L (micrograms per liter).

EPA: 50 µg/L before 1/91, 200 µg/L after 1/91 SMCL - U.S. EPA²
The U.S. EPA raised acceptable aluminum levels from 50 µg/L to 200 µg/L in January, 1991.²Just as the EPA raised acceptable radiation levels after Fukashima³, the EPA likely raised acceptable aluminum levels in anticipation of the enromous aluminum fallout that is generated by geoengineering programs. Interestingly, the EPA raised acceptable barium levels at the same time.

California: 50 µg/L SMCL - The California Department of Public Health²

Colorado: 50 to 200 µg/L SMCL - Colorado Department of Public Health and Environment¹

Definition of Secondary Maximum Contaminant level (SMCL)

"The SMCL means the maximum permissible level of a contaminant in water which is delivered to the free flowing outlet of the ultimate user of public water system."⁵

About EPA, The Federal Register, and the Raising of the Aluminum Limits in Drinking Water

Aluminum was proposed to have a Secondary Maximum Contaminant Level (SMCL) of 50 µg/L in the United States Federal Register on May 22, 1989. This was raised and adoped by the EPA to a wide range of 50 µg/L to 200 µg/L in 1991.⁴

As stated above, this change was likely proposed in anticipation of the considerable aluminum contamination from the rapidly-expanding geoengineering/chemical-aerosol spraying program. The EPA has now stopped testing for aluminum in an entire range of water tests.

Air

Summary: Under "normal" conditions, air contains from 0.005 to 0.18 μg/m3 (micrograms per cubic meter)

Most people take in very little aluminum from breathing. Levels of aluminum in the air generally range from 0.005 to 0.18 micrograms per cubic meter (μg/m3), depending on location, weather conditions, and type and level of industrial activity in the area. Most of the aluminum in the air is in the form of small suspended particles of soil (dust). Aluminum levels in urban and industrial areas may be higher and can range from 0.4 to 8.0 μg/m3.⁷

Blood Plasma

Summary: Blood plasma normallly contains 1 to 3 µg/L (micrograms per liter) of aluminum in a healthy human.

ATSDR²: 1 to 3 µg/L

Food

Summary: Aluminum in intravenous nutrition must not exceed 25 µg/L (micrograms per liter).

The FDA regulates the aluminum content of small- and large-volume parenteral drug products used in total parenteral nutrition therapy (intravenous nutrition). Aluminum must not exceed 25 µg/L.⁵⁰ The European Food Safety Authority (EFSA) set the weekly aluminum intake to 1 mg/kg body weight in 2008. This equates to 70 mg per week for a 70 kg person.⁵¹
