Is Little Rock tap water safe to shower in?
Yes, Little Rock's tap water meets all EPA drinking water standards, making it generally safe for showering. However, while safe for consumption, the presence of chloramine, disinfection byproducts, and water hardness can still negatively impact sensitive skin, hair, and respiratory health during showering.
Why does my shower water in Little Rock sometimes smell like chemicals?
That chemical smell, often described as bleach-like, is typically due to chloramine, which Central Arkansas Water uses for disinfection. While effective at killing harmful pathogens, chloramine can become volatile in hot shower water, releasing into the air and causing that distinct odor.
Does Little Rock's water hardness affect my skin and hair?
Yes, Little Rock's water is moderately hard, meaning it contains higher levels of dissolved minerals like calcium and magnesium. These minerals can leave a film on your skin, leading to dryness and irritation, and can make hair feel dull, brittle, and difficult to manage due to residue buildup.
How effective are shower filters for Little Rock's water?
High-quality shower filters can be very effective at reducing contaminants common in Little Rock's water, such as chloramine and its byproducts (TTHMs, HAA5). They can also help reduce heavy metals and sediment, leading to noticeable improvements in skin hydration, hair softness, and reduced respiratory irritation from steam.
Can Little Rock's shower water worsen eczema?
For individuals with eczema, the chloramine and hardness in Little Rock's shower water can indeed be problematic. Chloramine can strip natural oils from the skin, increasing dryness and irritation, while hard water minerals can leave residue that clogs pores and further aggravates sensitive, eczema-prone skin.
