What is the global prevalence of heavy metal contamination in drinking water and its associated health hazards?
Water Purification (Journal of Cellular Biochemistry 2017, PMID 28643849) — the predominant source of human exposure is contaminated drinking water, leading to health issues including cardiovascular disorders, neuronal damage, renal injuries, and increased risk of cancer and diabetes. No numeric effect size is reported for Water Purification in the source abstract.

Drinking water contaminated with heavy metals is a widespread problem causing significant health issues globally.
The question
What is the global prevalence of heavy metal contamination in drinking water and its associated health hazards?
What they tested
The abstract does not explicitly state a hypothesis, but it implies that heavy metal contamination in drinking water is a significant health concern leading to various adverse health outcomes.
How they did it
This article is a review that discusses the global contamination of drinking water with heavy metals, assesses associated health hazards, reviews the relationship between exposure limits and responses, and discusses acute and chronic poisoning symptoms and mechanisms.
What they found
Heavy metals such as arsenic, cadmium, nickel, mercury, chromium, zinc, and lead are present in drinking water above recommended limits. The predominant source of human exposure is contaminated drinking water, leading to health issues including cardiovascular disorders, neuronal damage, renal injuries, and increased risk of cancer and diabetes. The general mechanism of toxicity involves the production of reactive oxygen species and oxidative damage.
What it means
Consumption of heavy metal-contaminated water contributes to high morbidity and mortality rates globally due to the production of reactive oxygen species and subsequent oxidative damage, leading to various adverse health effects.
Limitations
As a review article, this study synthesizes existing information and does not present new experimental data or specific quantitative findings on prevalence or health impacts.

Water Purification (Reverse Osmosis & Ultrafiltration)
The health rationale for RO rests on evidence that the contaminants it removes are linked to disease: long-term exposure to trihalomethanes is associated with bladder cancer, drinking-water nitrate with colorectal cancer, inorganic arsenic with cardiovascular disease and several cancers, lead with cardiovascular…
