Freshwater Explorer Testkit


We designed our Freshwater explorer testkit for people of all ages.

No previous testing experience required. Our field guides and training videos include step-by-step directions on how to use the different tests, understand the results, and record your observations in our app. This kit is a great way for small organizations and individuals to gather data on their lakes and rivers without breaking the bank.

You can also add on a private training webinarIn it, one of our skilled Water Quality or Education Coordinators will teach you how to use your testkit and how to upload your results to our data platform.

You can also add your own custom design for an additional fee. These should be in a single colour as a simple line graphic. We will create a mockup for your approval!

Bulk discounts will be automatically applied to your cart. 5% off 10 or more. 10% off 20 or more.

Because of the ongoing supply chain situation, we ask that for big or urgent orders, you reach out to us before making your purchase to ensure we can help you get what you need!


Customize your testkit with your logo

You can add a simple, one colour logo to your testkit! We will let you know if your logo can work and send you a mockup of how it will look for your approval.

Parameter FAQs

For optimal results, E.coli tests require an incubator. We don’t currently sell supplies that test for E.coli, but we may one day. Learn more about E.coli here.

If you’re looking for an E.coli test, we recommend TapScore.

Just like with phosphates, this is another parameter where the tests we’ve tried aren’t sensitive enough unless you’re in a pollution event. Probes we’ve seen don’t seem very sensitive, and experts we’ve worked with aren’t sure how accurate they are.

We encourage our testers to browse our affiliate Tap Score’s testing services, which include products for phosphates!

We are currently conducting research involving tests for high level phosphates, but have yet to find tests that we’re happy with. Field tests that are currently available on the market can you let you know if phosphates are present, but can’t tell you to what extent they are present. In other words, they’re not quite sensitive enough to be useful! Also, many of the field tests require you to handle reagents that can be toxic, and that makes disposal difficult, meaning they wouldn’t be safe for kids to use. We are watching this space closely, and working with partners to see if this can change.

While our kits are designed to test lakes, rivers, and oceans, parameters like lead, copper, calcium, and unwanted chemicals are critical for determining the overall safety of city water. We promote groups like Tap Score who have created easy-to-use monitoring kits for your home.

Tap Score has designed kits to test city water and well water, depending on the source of your water. They provide you everything you need to collect a sample and send it to them. Upon analyzing it, a water health report will be returned to you in only a matter of weeks!

Partnership FAQs

That’s a great initiative! We’re always happy to partner with organizations, non-profits, schools, etc. to co-write a grant proposal to set up citizen monitoring programs. We’ve had good success in the past, but of course, we can’t guarantee anything. We’ve also prepared this fundraising toolkit to help groups think about how they want to set up their program.

We are always looking to partner with new or established organizations! We have launched a program that allows you to generate revenue for your organization while helping to grow the sustainable water monitoring movement. Take a look at our Ambassador Program to learn more!
