If you simply wish to have your water tested for informational purposes, you should contact a private laboratory for assistance. This applies to citizens either on City water or on well water. If you have City water and have a concern about the water quality, the water quality laboratory at the Northwest River Water Treatment Plant may be able to help you. Call 757-382-3550. If you have well water, contact the Chesapeake Health Department at 757-382-8600 for help.
