@Fastguy888 - I 100% agree with @Horton, I have done significant water quality lab testing (3 years in a lab), you will get what you pay for. For some chemical and biologic analysis I would not trust a DIY kit. I have used some in place sensors for various water properties, but those sensors were $2k+ per sensor and often only measured one or two attributes. I would not trust a $25 'kit' for anything more than temperature and maybe pH. In my current job I run a large agricultural facility we do annual soil, irrigation water, and quarterly ground water testing. All by private labs that keep our information private, we do pass the ground water testing on to relevant regulators but that is due to a permitting requirement from a spill cleanup situation from a few decades ago. The lab gives us the test results, we then supply to state regulator, the lab does not provide any information directly to the state.
The link I posted earlier has a few pages of private labs, I would give them a call, I bet it will be pretty easy to get your water tested and keep your information private.
I think the previous links were broken here they are again Example Lab and List of Labs
