water TESTING


Caminos de Agua offers water testing services for private clients, study groups, and community water sources. We charge for our private testing services to cover our costs, but can sometimes offer subsidized or free testing.


Before requesting any water testing, we strongly recommend that you read our Water Tips and look at our interactive Water Quality Map.


To start the water testing process now, click the button below …

… or to learn more about the process, follow our four steps detailed on this page:

  1. Learn about our testing options,

  2. Send us your testing request,

  3. Collect your water samples,

  4. Drop off your samples.


STEP 1 - LEARN ABOUT Our TESTING Options

COMPLETE TEST (Arsenic, Fluoride, Total Dissolved Solids (TDS), pH)

Price: 1,200 Mexican Pesos
Processing time: 28 days maximum

This test set covers the two most commonly-occurring mineral contaminants in the region – arsenic and fluoride – as well as giving information on the amount of total dissolved solids and the pH.

As well as conducting in-house testing for fluoride, total dissolved solids and pH, we will also send a sample of your water to an independent laboratory, EcoLaboratorios, located in Salamanca, Gto., who test for arsenic using atomic absorption spectroscopy.

REVERSE OSMOSIS (RO) SYSTEM EFFICIENCY TEST

Price: 200 Mexican Pesos
Processing time: 1 day maximum

This test will tell you how efficiently your RO system is working. However, it does not give you results on the specific levels of contaminants like arsenic and fluoride.

Currently, we do not offer testing for bacteria and pathogens. However, many other labs are able to test for these. Under special circumstances, we may be able to test for nitrates. Testing for all common contaminants can also be carried out through Ecolaboratorios, an independent laboratory trusted by us.

For more information on further testing, please visit our Other Testing page.

 

STEP 2 - Send your testing request

  1. Find two 1-liter plastic bottles. Normal water bottles are fine. They do not need to be new.

  2. Label the bottles. Write the following information on each bottle:
    - the relevant Bottle Code generated by the online form (sent to you by email),
    - your surname,
    - the date the sample was collected (e.g. 01-Jan-2000),
    - the relevant Bottle ID Label you specified in the online form (sent to you by email).

  3. Let water flow. Turn on the tap and let water flow for at least 30 seconds.

  4. Rinse the bottles. Part-fill the bottles with a small amount of the water, cap them, and shake them vigorously to clean. Repeat 3 times for each bottle.

  5. Fill the bottles.

  6. Store the bottles. Store the bottles in the fridge (or a cool, dark place if no fridge is available) as soon as possible.
