ONWASA says new lab results show no signs of potentially harmful chemical in Onslow Co. water system


HUBERT, N.C. (WNCT) – The Onslow Water and Sewer Authority reported Friday that new lab results show no signs of a potentially harmful chemical in Onslow County’s water system.

ONWASA shut down two water wells near Camp Davis last week as a precaution. Marine corps commanders notified the utility company after they found p-fas contamination in soil samples near the base’s landing strip.

“I shared our results and the base was like we are very happy,” said Jeff Hudson, ONWASA CEO. “We know until this point in time there is no PFAS that has entered the system because of the release that was aboard the base at Camp Davis South.”

The samples were taken about a mile away from the water wells. Company executives plan to conduct more tests on its underground water supply. They will keep the wells near the base offline until they have results.

“I know that the base has their own system, it’s a very detail system that they’re processing,” Hudson said. “I have a feeling we’re going to take input from GMA and move forward from there.”  

Officials also said the wells only provide a tiny fraction of ONWASA’s water.

“We want to make sure the movement of that water 150-250 feet underground is such that any chemical released on base doesn’t come into contact with D-10, D11, which are our two closest wells in proximity,” Hudson said.


JACKSONVILLE, N.C. (WNCT) — The Onslow Water and Sewer Authority said it has halted the operation of two water production wells in the Holly Ridge area after the discovery of a chemical that could lead to adverse health effects.

In a press release issued Friday, ONWASA said the move was made “following receipt of information on the presence of per-and-polyflouroalkyl substances (PFAS) at nearby Marine Corps Outlying Landing Field Camp Davis South (MCOLF Camp Davis South). The two ONWASA wells are within one mile of the landing field.”

ONWASA also said it has ordered laboratory testing to determine if there is any presence of PFAS within the wells. They say there is no evidence currently that PFAS reached the well sites.

The Environmental Protection Agency defines PFAS as” a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both chemicals are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects.”

ONWASA said it received information on Wednesday evening about the PFAS and “determined that two of the 10 deep aquifer wells in the Dixon well field were within one mile of the area of concern.” ONWASA said the two wells were taken offline at 6:16 p.m., less than an hour after they received the notice.

Water samples were gathered from the wells on Thursday and delivered to an independent lab in Wilmington for testing. ONWASA expects to hear the results on Feb. 4 and released to the public on Feb. 5.

Citizens who have questions about the ONWASA water system may contact ONWASA at (910) 455-0722. Citizens who have private water wells in the area or who have questions regarding the release of PFAS aboard MCOLF Camp Davis may contact the MCI-EAST Public Affairs Officer, Mr. Nat Fahy, at (910) 451-7413.
