In the aftermath of “Harvey”

Our thoughts are with the countless families and businesses that have suffered in Texas as a result of Hurricane Harvey. During this crisis public health is a major concern. Please reach out to us if we can assist with your environmental testing needs. We are fully operational and ready to support your environmental testing needs in the aftermath of this catastrophic event. 

Operations back to normal

Our Stafford lab in the Houston area is now accepting shipments and walk-ins. Our operations have returned to normal and we are grateful that our facilities were spared during the Harvey Hurricane and subsequent floods.  We want to thank all our clients for their patience and support during this event.

Shipping samples during the Houston flood

Due to continuing extreme flooding in Houston as of Tuesday August 29, we would like to ask all our clients that ship samples to our Stafford laboratory, which is located in a Houston suburb, to ship all samples temporarily to our Dallas lab until Thursday of this week, August 31st. Use this shipping address:

Xenco Laboratories

9701 Harry Hines Blvd

Dallas, TX 75220

Our Houston facility has been spared from the flood, thankfully, but due to road conditions, to our employees safety, and to airport closure, we are only keeping an emergency crew that is handling rush and emergency-response samples in our mail lab. Houston airports are expected to reopen on Thursday August 31st, so please wait until that date to start shipping back to our main lab at Stafford.

Possible business disruption by Hurricane Harvey

The expected effects of Hurricane Harvey are very likely to disrupt our operations at Xenco. While we are fully prepared internally to offer regular and emergency services, things outside our control such as disruption in shipment by FedEx, power outages, and serious transportation problems are likely to affect the timeliness of our regular and rush testing. The hurricane is expected to cause problems starting today, Friday the 25th and possible until the middle of next week. We apologize for the inconveniences this may cause our clients.

Xenco is an emergency response laboratory so there will be a crew dedicated to providing emergency services.
