Chloride Contamination in Drinking Water Around Tampa Bay

Chloride is a negatively charged ion that combines with positively charged ions like sodium, potassium, and calcium to form salts. At low levels, chloride is essential for human health and gives water a salty taste. However, at high concentrations, chloride can make water unsafe to drink.

In areas near Tampa Bay, chloride contamination in drinking water is an issue of growing concern. Excess chloride in water can come from several sources, including seawater intrusion, wastewater discharge, road salt runoff, and natural deposits. Prolonged exposure to high chloride levels can have adverse health effects. Furthermore, chloride does not have a taste or odor, so contaminated water may smell and look fine. The only way to know chloride levels is through water testing.

Presence of Chloride Contamination in Tampa Bay Area Drinking Water

Chloride contamination has been detected at unsafe levels in certain counties, cities, and neighborhoods surrounding Tampa Bay. Locations with chloride contaminated well water or municipal supply include:

Pinellas County

  • Clearwater

  • Clearwater Beach

  • Indian Rocks Beach

  • Oldsmar

  • Palm Harbor

  • Pinellas Park

  • Safety Harbor

  • Seminole

  • Tarpon Springs

Pasco County

  • Holiday

  • Hudson

  • New Port Richey

  • Port Richey

  • Saint Leo

  • San Antonio

  • Spring Hill

  • Zephyrhills

Hillsborough County

  • Apollo Beach

  • Gibsonton

  • Lithia

  • Lutz

  • Mango

  • Ruskin

  • Sun City Center

  • Tampa

  • Valrico

Chloride contamination affects both private well owners and those on city water in these areas. Tampa Bay's location along the coast makes the region prone to seawater intrusion of aquifers. Old infrastructure also leads to chloride contaminated wastewater leaching into ground and surface water.

Health Concerns of Chloride in Drinking Water

The EPA secondary standard sets the recommended chloride concentration in drinking water at 250 mg/L. However, Florida's Department of Health has a more stringent drinking water standard of 160 mg/L.

Drinking water with chloride exceeding these levels is considered unsafe. Health problems linked to high chloride intake include:

  • Hypertension and cardiovascular issues

  • Kidney dysfunction

  • Changes in cholesterol levels

  • Imbalanced blood acidity

  • Impaired liver function

  • Reproductive issues

Infants, young children, pregnant women, and those with existing health conditions are most susceptible to the effects of excess chloride. Though acute toxicity is rare, long-term exposure to high chloride drinking water can cause chronic health problems.
