Water Quality Testing

Water Quality Testing

Various laboratories in Texas conduct water quality testing. The laboratory you use depends on whether you are testing your water to determine if it is safe for human consumption or if you are testing water that will be used for other purposes (irrigation on your property, a pond with fish in it, swimming, etc.)
