DEPARTMENTS - Wet Chemistry

We are pleased to offer both traditional and progressive wet chemistry parameters for drinking water, waste water, ground water, surface water, pools and spas. We are certified for as many parameters as possible, however, Mass DEP does not certify all these tests in all matrices. Note that there may be some parameters on your state required test list that the state does not certify. For example, some towns are required by the state to test for phosphate in their drinking water. Mass DEP does not certify any method for the testing of phosphate in drinking water, however, we are still capable of doing compliance testing in these cases.

Single test pricing is given. Keep in mind that we have battery pricing which may give you the parameters you need at a much lower price. We also have contract pricing if you have ongoing needs. If you do not see the parameter you need, please contact us, as we may offer it under a different name, or be able to accomodate a special request. You may also find what you need on another department page: Metals Microbiology Organics and Radionuclides. Using your browser “find” function may also help you locate what you are looking for. Note that we also will test solid matrices, such as soil and some food products. Please contact us for more info on testing non-water matrices.

x = Mass DEP offers certification for this method in this matrix and we are certified.

o = Mass DEP does not offer certification for this method in this matrix, however we test for these using
the same rigorous QC program

s = These samples will be subcontracted to a certified lab

* = Requires packaging with and purchase of additional parameters. Please inquire for more info.
