✅ What You Can Do About It
Test Your Shower Water
Understanding specific contaminant levels in your home's water allows for targeted solutions, as water quality can vary even within Brownsville's distribution system.
Install a Quality Shower Filter
A good shower filter can significantly reduce chloramines, disinfection byproducts, heavy metals, and other contaminants, leading to softer skin and hair and improved air quality.
Reduce Shower Time and Temperature
Shorter, cooler showers minimize exposure to contaminants that volatilize into steam and reduce the amount of time chemicals have to absorb into your skin.
Moisturize Immediately After Showering
Applying a moisturizer to damp skin helps to lock in hydration and create a protective barrier against the drying effects of hard water and chemicals.
Clean Showerheads Regularly
Regularly cleaning your showerhead prevents mineral buildup and bacterial growth, ensuring optimal water flow and reducing exposure to accumulated residues.

Is Brownsville tap water safe to shower in?
While Brownsville's tap water meets federal safety standards for drinking, contaminants like chloramines, disinfection byproducts, and hard minerals are still present. These can negatively impact sensitive skin, hair, and respiratory health, suggesting that 'safe' is relative to individual sensitivities and concerns.
Does Brownsville water cause dry skin and hair?
Yes, Brownsville's water is known to be hard and treated with chloramines. These factors can strip natural oils from your skin and hair, leading to dryness, irritation, and a dull appearance, especially for those with existing sensitivities.
What causes the 'chlorine' smell in Brownsville shower water?
The distinct smell often attributed to chlorine is actually due to chloramines, which are used by Brownsville Public Utilities Board (BPUB) for disinfection. These compounds can volatilize in hot shower water, releasing a noticeable chemical odor.
How do shower filters help with Brownsville's water?
