Extended City Water Test

Designed for customers paying a water bill to a local utility. This package covers our broadest range of potential threats that water systems sometimes miss, and some they can't catch.

US infrastructure has been chronically under-funded for decades. Because of this many water systems have resorted to shortcuts in testing and treatment. These shortcuts sometimes leave utility customers with contaminated water. Even if water leaving the treatment plant is clean, it takes a 3-7 day journey to your home through a network of aging pipes that sometimes introduces new contaminants into your water.

The Extended City Water Test adds testing for Chlorate, five Haloacetic acids, and radioactive particles to the Advanced City Water Test.






Who is this for?

This package is designed for customers who:

  • Are served by a water utility they have doubts about.
  • Live in a home built before 1986 or an area served by old infrastructure.
  • Have young children or other vulnerable individuals in their home.
  • Want to check for chemicals from plastic pipes.
  • Are concerned about over-chlorination and the resulting chemicals.
  • Want to include testing for chlorate, haloacetic acids, and radioactive particles in their test.

What does this test for

testing by a certified lab

A note from our Environmental Science Director:

There are more than 160,000 public water systems in the USA. Each can be dramatically different from another in terms of size, source water quality, treatment engineering, distribution and public relations management. Moreover, the water quality within any one water system will also vary significantly for every customer due to distance, piping age and connection type.

All testing is performed with EPA certified testing methods. This package includes testing for:

measure the concentration of chlorine in your water
Testing for chlorine at home

The most sensible way to test your chlorine levels is with self-testing. Chlorine is a very volatile chemical and properly measuring chlorine in the lab requires very expensive shipping methods and refrigeration. In order to give you the most effective reading on your home's chlorine levels your package includes two FREE chlorine test strips. The strips we send you will show if your chlorine levels are abnormally high (or low) in your water.

Frequently asked questions

What do I do if my score is low? I can't change my water system!

After an in-home water test, you can make the right decision about the costs and benefits of treatment. Many treatment companies will otherwise offer expensive products that are drastic overkill or just overpriced. To help you avoid this pitfall we give you our unbiased treatment product recommendations, matching contaminants in your Tap Score Report to affordable, high quality treatment products specifically tailored for your needs.

How often do people in public water systems find nasty stuff in their water?

More often than you’d expect. Surprisingly, the proportion of customers with city water that find a potential health hazard in their water is only slightly smaller than for customers with unregulated well water.

Is this test overkill? What is it protecting me from?

The Extended City Water test is the most comprehensive of our general city water focused offerings. It includes some disinfection byproducts that are common but are unfortunately too costly to include in the Advanced test. It also includes a general screen for radioactive alpha and beta particles.

Informational testing

By default, this broad-based chemical and biological water quality screening package is designed to provide you with general information about your water for personal use. Each report includes analysis for specific numerical concentration levels of each contaminant and details about the potential sources and health effects associated with each parameter. We are not medical doctors and Tap Score does not provide medical advice. For medical concerns always consult your doctor. As an informational water quality test, this package is not meant for state or federal compliance water testing. If you or your organization requires compliance with State or Federal Law, or compliance with a particular regulatory requirement then you must contact our support team and we will use the appropriate certified laboratory facilities to ensure your compliance testing requirements are met.
