Routine Domestic Water Analysis

What is a Routine Water Analysis?
(a.k.a. a Routine Domestic Panel, a Routine Domestic Analysis, or an "Escrow Package") Routine domestic water analyses are usually requested by private well owners for their own drinking water quality information, or to satisfy a lender's requirement for a pending real estate sale. These analyses determine the concentrations of several water quality indicators in drinking water.

When done as a condition required by a lending institution for the transfer of real property, the testing must be performed by a laboratory certified by the State of Nevada under the Safe Drinking Water Act (SDWA). The lab can be certified for one or all of the items of interest. If the laboratory is not certified for all the items typically requested by Lenders, it may subcontract those tests to another Nevada Certified Laboratory.

Not all laboratories are certified under the SDWA. Many labs are certified under the Clean Water Act (CWA) or Resource Conservation Recovery Act (RCRA) but may not have SDWA certification.
NRS 455A.863
Only laboratories that have State of Nevada SDWA certification are eligible to perform drinking water testing "required by a lender as a condition precedent to the transfer of real property".

The question to ask the laboratory is:

Are you certified by the State of Nevada to analyze Drinking Water compliance samples?

The following table contains a list of in-state Nevada Certified Drinking Water Laboratories that accept samples from the public. You can click here [xlsx file] for additional detail on the analyses that they are currently certified for. Additional out-of-state laboratories are also certified for Drinking Water.

This list was last updated February 2016. Generally, this list will be revisited annually for website posting. If you have questions or concerns, please contact with the NDEP Laboratory Certification Program.

How much will it cost?
Costs will vary from lab to lab. Generally the total cost can be around $100, but will most likely not exceed $500, depending on what is requested

What if I use a lab that is not certified to analyze drinking water samples?
The state cannot provide any degree of confidence that the results are accurate or reliable. In addition, any non-certified laboratory providing this service is operating outside Nevada Law.

What do the results mean?
University of Nevada Cooperative Extension has several publications that may be of help.
