With over 20 years experience in the water treatment business, D W Environmental Systems is now at your service when you need an independent, reliable person to come to your site and test your water source before the drilling of any type of oil or gas well, whether shallow well or deep Marcellus Shale well. We will come to your home or water supply site, collect the water samples in the proper manner to prevent contamination and transport the samples for immediate testing to a Pennsylvania DEP Accredited Laboratory in accordance with the Chapter 252 DEP Accreditation Requirements. If you have a problem with your water supply at some later date, after the drilling of the oil or gas wells, we will be an independent third party that can verify the quality of water you had before the drilling was performed and provide you with the credible results you will need. Call us today.
