Perchlorate Water Test

Perchlorate in Drinking Water: A Serious Threat to Thyroid Health

Perchlorate is a chemical compound found in rocket fuel, missile propellants, fireworks, and certain fertilizers. It does not break down easily in the environment, and once it enters a water supply it can persist for years. Unlike many contaminants that affect water taste or appearance, perchlorate is completely colorless and odorless, making it impossible to detect without laboratory testing.

Perchlorate contamination in drinking water is most commonly associated with areas near military bases, defense contractors, aerospace facilities, and agricultural regions where certain fertilizers have been used historically. Both private wells and municipal water supplies can be affected, and contamination has been detected across numerous states.

The primary health concern with perchlorate is its effect on the thyroid gland. Perchlorate interferes with the thyroid’s ability to absorb iodine, which is essential for producing hormones that regulate metabolism and development. For pregnant women, this disruption can impair fetal brain development and cause lasting neurological damage. Young children are also particularly vulnerable as thyroid hormones play a critical role in healthy growth and cognitive development.

How It Works

Order your test and we will mail you a sample collection kit with easy-to-follow instructions. Collect a water sample from your tap and send it back to our in-house laboratory. Results are delivered within 3 to 5 business days from the date your sample arrives.

Understanding Your Results

Perchlorate results are measured against EPA health advisory levels and can be difficult to interpret without context. Every test includes a free consultation with one of our in-house water quality experts. Simply reach out by phone or email after receiving your results and we will walk you through what was found, what it means for your household, and help you determine the right next steps if anything of concern is detected.

This test is strongly recommended for households near military installations, defense industry facilities, or aerospace sites, well owners in agricultural regions where fertilizers have been historically used, and pregnant women or families with young children who want to rule out thyroid disrupting contaminants in their drinking water.
