After looking for testing labs on the internet, I found Karlabs appeared to be exactly what I was looking for. After reading through their website, I did a web search for reviews. I reviewed dozens of reviews and they sounded very good. I chose Karlabs to test our new well. My results were returned just as they said and fast. Every step went perfectly smooth. Finally, a company that actually does what they say to the letter. Thank you Karlabs. I will be back next year.

This is my third year of getting my well water data. As a former Quality Control manager I am impressed with the both the speed and accuracy of my results. Nice job !

I had a professional test my well water then I decided to do a test with your product. It was less expensive and more informative to purchase from you than to have a professional do my well testing. Thank you so much. Hi

Affordable cost! Quick (2day) results for the water test (#90)I ordered! Great follow-up- to make sure I received my results and had any questions! I'm impressed.

It is unfortunate that so often problems arise in the purchase of a service or product. This was NOT the case in our dealing w/ Karlabs, a consumers' paradise. I got what I ordered, promptly, and at a fair price. I had sent them my e-mail [but part of it was illegible] - I was contacted by a very courteous young lady who quickly corrected my error.
If there was a six-star rating system, that's what I would give Karlabs!

We here at the Sierra Club New York Water Sentinels deeply appreciate your commitment to provide the comprehensive lab tests that we need to monitor water quality of at-risk stream and drinking water sources - at a price that we can afford.
We are an all volunteer group of about 100 stream monitors in local county "Groups" in every NY county that borders Pennsylvania. We rely entirely on financial support from local concerned citizens groups - our budget is very limited.
We would not be able to maintain our program of (1) stream water pollution testing when we suspect a pollution incident has happened and; (2) our program of outreach to people who are concerned that their drinking water quality has been compromised... without your low prices, lab advice, and personal support. We appreciate your dedication to environmental water testing and the personal concern demonstrated by your top management.
