WATER CHARACTERISTIC

Total dissolved solids

The combined amount of dissolved minerals and salts. It adds context to water quality; it does not identify every contaminant or establish safety on its own.

Comprehensive packageAsk about Total dissolved solids

pH, hardness and total dissolved solids describe water characteristics. They are not individual contaminants. Test selection depends on the water source and your specific needs.

BEFORE YOU BOOK

Common questions

Request water testing
Which water package should I choose?

Start with the tests you need or any instructions you’ve received. Basic Well Water covers coliform, E. coli and nitrate. Home Water Check adds lead and copper. Comprehensive Water Check adds nitrite, iron, manganese, pH, hardness and total dissolved solids. Call if you’re unsure.

Can I request just lead and copper, or just bacteria testing?

Yes. Lead and copper, and total coliform and E. coli, can be requested as paired tests. You can also ask about an individual contaminant or another combination. We’ll confirm pricing for your request.

Should I collect a sample myself?

Contact us before collecting water. Preparation, containers and collection methods depend on the test. We’ll explain the next step for your request.

Does one package test for everything?

No. Each package covers only its listed tests. If you have a specific contaminant, lender requirement or other concern, share it before booking so we can confirm the needed scope.

How do I book a package?

Use any request button to open our Jotform. Choose Other and enter the package name if it isn’t listed. We’ll confirm the testing scope and final price before scheduling.
