What Are Our Clients Saying

We run a school on the East side of Manhattan and needed the water tested at every faucet and fixture throughout our facility. This was not their first rodeo. They were on time, knew exactly what to do, and provided not only the lab results, but their credentials, floor plan diagrams and everything expected of a quality water testing service provider.

We had our restaurant water supply checked at all sinks we use for food preparation. They were very reliable and professional. We got a fast call about the presence of E.coli in one of the samples.

After having brown water for a week straight, I found Olympian online and they came and tested the next day. Problem found and now being taken care of by the building management Premium quality water testing services were provided.

Good and honest businesses can sometimes be hard to find. This one is a diamond in the rough. I highly ecommend you give them a try.

Olympian Water Testing Did very comprehensive water testing and found a whole lot wrong in our building water. Great choice to work with.
