“I had the pleasure of dealing with BioTech Laboratory this summer. After my store-bought water test failed I did some research on local water testing companies and was (and still am) impressed with BioTech’s web site. They supplied clear, concise information, pointers to other helpful resources, and instructions (with pictures, helpful when visuals stick in your brain). I fully support their suggestion to call them the evening before testing – it made me really think through the process so when I actually collected the samples the next day it was done without any second guessing whether or not I understood the procedure. And I commend Ed and Karen on their communication and post-testing support. I appreciate their time and effort throughout the entire process – thank you both.” (Google Review – 5 stars)
