How Richardson's Water Affects Your Skin and Hair
You might think your tap water is only a concern when you drink it. But your skin is your largest organ, and studies show you absorb more chlorine through a 10-minute shower than drinking 8 glasses of the same water.
Here's what Richardson, TX water contaminants do to your body:
- Dry, itchy skin: Chlorine and chloramine strip your skin's natural oils, causing dryness, irritation, and eczema flare-ups
- Hair damage: Hard water minerals coat hair strands, making them brittle, dull, and prone to breakage and thinning
- Acne and breakouts: Chemical residues clog pores and disrupt your skin barrier, triggering inflammatory acne
- Color-treated hair fading: Chlorine is a bleaching agent — it strips hair color faster than anything else
Cancer-Linked Contaminants in Richardson Water
16 contaminants detected in Richardson, TX water are linked to increased cancer risk:
- Total trihalomethanes (TTHMs) — cancer
- Haloacetic acids (HAA5) — cancer
- Bromodichloromethane — cancer
- Dibromochloromethane — cancer
- Dichloroacetic acid — cancer
- Trichloroacetic acid — cancer
While these levels may be within legal limits, the EWG notes that legal doesn't equal safe. Many of these legal limits haven't been updated in 20+ years.
Where Do These Contaminants Come From?
The contaminants in Richardson's water come from multiple sources:
Your local water utility treats the water to meet federal standards, but treatment itself creates byproducts (like trihalomethanes and haloacetic acids) that carry their own health risks.
