water testing devices

ive run into another information overload subject. on an episode of homestead rescue misty Rainey used a little handheld and device to test well water from a well that the landowner thought might have been contaminated.
I have no idea what she was able to test for but went searching for water testing devices.  I quickly ran into information overload not having any expertise in chemistry or biology.

I found this device site

anyone have ideas on such devices that can measure hazardous materials and bacteria at a reasonable cost?

To my mind, the problem is knowing what to test for. Water is a near-universal solvent and transport medium. Just about anything could be in there.

I suspect it would cost a fortune to purchase all the equipment needed to cover all the bases. Plus, there's the cost of replacing consumable items (test strips, sensors) and keeping the equipment calibrated.

Personally, I would take it to a lab and pay the fee.

If you wanted to know more about hazardous materials and bacteria at a reasonable cost. I would contact your local water office. They would have contacts for labs who can test your water.  The upside is the tests would give you a better idea of what is in your water and they will hopefully talk to you about treatment options if you want some help. At a local level water treatment places send in samples on a monthly or sometimes weekly schedule.  

I know that in this part of the world the university of Georgia extension service has one of the best water and soil testing services that there is. but had a thought that a little handheld device at reasonable cost could come in very handy.
my daughter who has a bs in biology sent me an urgent message not long ago saying there are micro plastics in the rain. and with the well have that has changing water quality every time its rains a lot a little device to test for nasties would be good gadget to have.
