SUMMARY

The discussion centers on the Maximum Allowable Limit (MAL) of cadmium in soft water, specifically addressing its implications for human health. The U.S. Environmental Protection Agency (EPA) has established a limit of 0.005 mg/L for cadmium in drinking water, emphasizing that this concentration is imperceptible to the naked eye. Additionally, the World Health Organization (WHO) recommends a slightly lower limit of 0.003 mg/L. Understanding these limits is crucial for ensuring safe drinking water standards.

PREREQUISITES
  • Knowledge of water quality standards
  • Understanding of cadmium's health effects
  • Familiarity with the U.S. EPA regulations
  • Basic concepts of water chemistry
NEXT STEPS
  • Research the health effects of cadmium exposure
  • Study the U.S. EPA's water quality regulations
  • Explore WHO guidelines on heavy metals in drinking water
  • Learn about water treatment methods for cadmium removal
USEFUL FOR

This discussion is beneficial for environmental scientists, public health officials, water quality analysts, and anyone involved in water safety and regulation compliance.

TL;DR
Mal of Cadmium in soft water
What does ‘MAL (is it Maltol) of cadmium’ in soft water mean?
 
Chemistry news on Phys.org
MAL = maximum allowable limit - Cadmium is not good for humans to ingest or drink, so acceptable levels of cadmium in drinking water, for example, have limits. VERY small ones.
US EPA has set a limit of .005mg/L - You could not see a .005mg speck of Cadmium with the naked eye.

Many thanks. Who guidance .003mg/L. No problem. Thanks for simplifying that riddle.
