Sparkletts water is better than Arrowhead. Sparkletts water has no detectable arsenic, no detectable total trihalomethanes, and no detectable chloroform. Some bottles of Arrowhead water have detectable levels of all of these dangerous chemicals. However, some bottles of Sparkletts water have tested as being contaminated with bacteria.
Trihalomethanes in drinking water may cause birth defects or miscarriages if a pregnant woman drinks the contaminated water. Trihalomethane is a byproduct of water chlorination. Chloroform in drinking water can cause liver, kidney and nervous system toxicity. Arsenic in drinking water can cause skin damage, problems with the circulatory system and an increased risk of getting cancer.
