Test my water

We offer free standard testing and subsidized arsenic 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

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:

  • ANY CLIENTS WHO CHOSE STANDARD TEST SET + ARSENIC
  • URBAN AND RURAL COMMUNITY GROUPS
     
  1. Find two containers: Find two empty PLASTIC bottles or containers, each with a capacity of 1 litre or more. Normal water bottles are fine. They do not need to be new, but 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 containers: Half-fill the containers with sample water, cap them, and shake them vigorously to clean. Repeat this 3 times for each container.
  4. Fill the containers: Fill the containers with 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 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.

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").
