Chromium 6 Contamination in Drinking Water Around Tampa Bay, Florida


Chromium 6, also known as hexavalent chromium, is a dangerous drinking water contaminant that has been detected in water sources across Florida, including in counties and cities around Tampa Bay. This known carcinogen can have severe health impacts when consumed over long periods of time, even at low levels. In this article, we will discuss the presence of chromium 6 in the region's water, associated health risks, and water treatment solutions for removal.

Presence in Drinking Water

Chromium 6 has been found in varying concentrations in the tap water of many municipalities that source from groundwater wells across Florida. This includes cities and communities in Hillsborough, Pasco, Pinellas, and other counties surrounding Tampa Bay.

The contaminant often enters groundwater through natural deposits or industrial contamination. Chromite ore processing, steel production, chrome plating, dyes and pigments manufacturing, leather tanning, and wood preserving are key sources of chromium 6 pollution. Runoff or improper disposal of chromium 6-laden waste has resulted in aquifer contamination in Florida.

Health Concerns

The United States Environmental Protection Agency (EPA) and the World Health Organization (WHO) have classified chromium 6 as a known human carcinogen when inhaled. Studies have also confirmed the chemical's cancer-causing effects when ingested through drinking water over extended periods.

Chromium 6 does not naturally occur in water sources. It is the toxic form of chromium that can come from the erosion of natural chromium deposits or industrial waste. In contrast, chromium 3 is an essential human dietary nutrient found in many vegetables, meats, grains, and yeast.

According to the EPA, chromium 6 has the potential to cause the following adverse health effects when consumed through drinking water:

  • Stomach tumors

  • Liver damage

  • Reproductive issues

  • Damage to circulatory, nerve, digestive, and immune systems

Sensitive populations like children, pregnant women, and those with compromised immune systems are at greater risk from chromium 6 exposure. Research indicates increased cancer risk even at concentrations lower than the current EPA legal limit of 100 parts per billion.

Prolonged consumption of drinking water exceeding California's public health goal of 0.02 parts per billion poses significant cancer risk. While federal and Florida guidelines remain higher, experts urge close monitoring and treatment to remove chromium 6 from drinking water for optimum health and safety.
