Test my water

We offer free testing to study groups, community groups and to certain other groups who have made special alternative arrangements, to allow us to better monitor the water sources that serve large numbers of users. If you are testing any water source where many people’s health may be affected and/or if you are unable to pay, we may be able to test for free.

Private clients are charged a fee for their testing – money that helps us to ensure we can continue to do the work we do.

 

HOW CAN I GET MY WATER TESTED?
 

  1. If testing as a private client, then first consider which type of testing you would like(If you are part of a local study groupcommunity group, or if you have made special alternative arrangements for testing, continue to step 2.)
  2. Complete an online form to send us your details
  3. Collect your sample(s)
  4. Drop off your sample(s) at our lab
 

Step 1 – Consider which type of testing you would like

FULL TEST (ARSENIC, FLUORIDE, TOTAL DISSOLVED SOLIDS, PH)

Cost: 750 Mexican Pesos
Processing time: 2 weeks
Description: This test 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.

QUICK REVERSE OSMOSIS (RO) SYSTEM EFFICIENCY TEST

Cost: 200 Mexican Pesos
Processing time: 24 hours
Description: Do you have a reverse osmosis (RO) system and want to do know if it’s working correctly? This test does not give you results on the specific levels of contaminants like arsenic and fluoride, but it will tell you how efficiently your RO system is working.

OTHER TESTING (E.G. BIOLOGICAL, NITRATES ETC.)

Cost: Dependent on request.
Processing time: Dependent on request.
Description: We are able to test for other contaminants upon special request. We have the capacity to test for total coliforms and E. coli (a potentially harmful fecal coliform) using the widely renowned IDEXX Quanti method, which is used as standard by governments around the globe. We are also able to test for nitrates, which may present a problem in surface water in high-intensive agricultural areas. Such tests can also be combined with one of the tests above, on special request.

Bacteria testing alternatives: If you are looking to test for bacteria, you may find it quicker and easier to test through another lab in San Miguel. Click here for a list of options.

 

STEP 2 – COMPLETE AN ONLINE FORM TO SEND US YOUR DETAILS

Please note, if you would like to test your water through Caminos de Agua's Lab, you may need to know your GPS coordinates.

STEP 3 – COLLECT YOUR SAMPLE(S)

Once you have completed the online form above to send us your details, then you're ready to collect your water sample(s)! Here are the instructions for how to collect them:
 

IMPORTANT NOTE
W
e recommend collecting sample(s) at most 2 days before dropping them off at the lab (and preferably on the same day).
Therefore, ideally, samples should be taken on a Sunday, Monday or Tuesday before drop-off on the Tuesday afternoon, when the lab is open.

 

COLLECTION INSTRUCTIONS FOR:

  • PRIVATE CLIENTS WHO CHOSE FULL TEST,
  • PARTICIPANTS OF THE UWQMP
  • URBAN AND RURAL COMMUNITY GROUPS
  • THOSE WHO HAVE MADE SPECIAL ALTERNATIVE ARRANGEMENTS FOR TESTING
     
  1. Find a container: Find an empty PLASTIC bottle or container with a capacity of 1 litre or more. A normal water bottle is fine. It does not need to be new, but it must be plastic.
  2. Let water flow: Turn on the tap (or sample water source) and let it run for 2-5 minutes, if you can.
  3. Clean the container: Half-fill the container with sample water, cap the container, and shake it vigorously to clean. Repeat this 3 times.
  4. Fill the container: Fill the container with sample water and cap it tightly.
  5. Label the container: Write the following on the container in permanent marker: your name, the first line of your address, and the date the sample was taken, and a brief description of the water sample (e.g. "treated kitchen water - reverse osmosis system" / "UWQMP" / "community well water").
  6. (If you are submitting multiple samples for testing): Repeat these steps for each sample you would like to submit for testing.

 

COLLECTION INSTRUCTIONS FOR:

  • PRIVATE CLIENTS WHO CHOSE QUICK RO SYSTEM EFFICIENCY TEST
     
  1. Find two containers: Find two PLASTIC OR GLASS bottles or containers with a capacity of at least 100 mL each (but preferably at least 500 mL). A normal water bottle is fine.  They do not need to be new, but they must be plastic or glass. One container will contain pre-filter water (water from the normal tap) and the other will contain post-filter water (water that has been treated by the filtration system you want to test).

  2. Let water flow: Turn on the tap (or sample water source) and let it run for 2-5 minutes, if you can. Do this for both the pre- and post-filter water sources if possible.
  3. Clean the containers: Half-fill the container with the relevant sample water, cap the container, and shake it vigorously to clean. Repeat this 3 times. Do this for each container, using the relevant sample water for each.
  4. Fill the containers: Fill each container with the relevant sample water and cap them tightly.
  5. Label the containers: Write the following on each container in permanent marker: your name, the first line of your address, the date the sample was taken, and whether the container contains normal tap water (write "pre-filter") or water treated by your filtration system (write "post-filter").
 

STEP 4 – DROP OFF YOUR SAMPLE(S) AT OUR LAB


Once you have submitted your details using the online form above, and collected your sample(s), then you're ready to drop off the sample(s) at our lab!

All water samples should be dropped-off on TUESDAYS BETWEEN 2 PM AND 5 PM. There is no need to book an appointment. Please do not come at another time, as there may not be anyone at the lab to receive your sample(s). If coming at this time is a problem for you, then please contact us using the details below.

If you chose to pay by cash when submitting your details, then please remember to bring cash with you when you come. Exact change is appreciated.
 

IMPORTANT NOTE
No samples will be tested unless an online form has been completed, and the sample container is correctly labelled (as detailed here).
