Hardness Water Test

1 Analyte Tested
$69.00 USD

Recommended for targeted testing of hardness level in drinking water.Water is normally considered “hard” if it contains high levels of dissolved and positively charged minerals, such as calcium and magnesium. It is estimated that 85% of U.S. drinking water has some degree of hardness and while it is not a health hazard, it can have nuisance/aesthetic effects.

Signs of hardness include clogged pipes through the formation of mineral deposits (also called "scale), white buildup and residue on fixtures, inability to form a lather or sudsing of soap, damage and malfunctions of water-related equipment like heaters, kettles, and cooling towers.

What’s inside your testing kit?

Sampling Instructions

Every test comes with step by step instructions on how to prepare your water source, collect your water sample, and prepare your sample for return shipment to our labs.

Collection Bottles

Your kit includes all the bottles, tubes or vials necessary to collect your water sample. For most kits, however, there is only one collection bottle needed.

Sample Information Card

Your kit includes a postcard that asks for a few details about how and where you collected your sample (i.e. kitchen faucet). Just fill it out, drop it in the return box, and we'll do the rest.

Prepaid Shipping Label

Shipping is always on us. This package includes a prepaid return shipping label to the lab. Just stick the provided label on the outside of the box and drop it in the mail.

Return Container (If Applicable)

Some of our tests require your water sample to be cold when it reaches our labs. If this applies to your test, the proper refrigeration items will be included.

SUPPORT

Which test is right for me?

When in doubt, start with a Core Kit to analyze multiple contaminants with a single test. If you have more specific motivations for testing, try our Customize My Kit feature to match your needs to the right test(s).

What's the turnaround time?

Most people receive results within 3-5 business days after the lab receives their sample. However, some tests may require additional analytical time so be sure to check each kit’s product page for the most accurate estimate.

What will my report include?

Your report will rank your water against local and federal safety benchmarks, provide a thorough breakdown of any contaminants detected and how they may be affecting your health or plumbing, and provide non-biased treatment recommendations.
