The N.C. Department of Environmental Quality (DEQ), in consultation with the N.C. Department of Health and Human Services (DHHS), is leading a state investigation into GenX, an unregulated chemical, in the lower Cape Fear River. DEQ has collected water samples from 12 sites along the Cape Fear River and the results of those samples can be viewed here.

Test results from water samples will be used to analyze drinking water safety and the EPA is developing an updated health screening level for GenX to help with this process. DHHS is reviewing all available health data and working with the EPA and the Centers for Disease Control to get their guidance about health risks of GenX. To learn more about the efforts of DEQ, click here.

In addition, DEQ’s Division of Water Resources is monitoring 1,4-dioxane, an emerging contaminant, at locations in the Cape Fear River basin. Learn more about their study here.

On June 29, the NC Department of Health and Human Services (NC DHHS) released information, after examining data from the North Carolina Central Cancer Registry, that cancer rates in New Hanover County are generally similar to statewide rates of cancers. A copy of the summary can be viewed here. DHHS provided this information to answer questions raised about cancer during the ongoing investigation of GenX in the Cape Fear River. New Hanover County Health Director Phillip Tarte made a statement after learning this news, and it can be viewed here.


On June 16, NC DHHS provided public health officials with the following statement: DHHS is continuing to work with EPA and reviewing all available science to provide partners and the public with the most current health risk information for GenX. This includes continuing to refine and update the health screening level as new information becomes available. As a reminder, health screening levels are non-regulatory, non-enforceable levels that represent the level below which no adverse health effects would be expected. Any changes to health screening levels will be shared with partners as soon as possible. Currently, there is no change in our assessment that health effects are unlikely at the levels detected in the Cape Fear River during 2013-2014.
