VERNON -- The state Department of Environmental Protection has ordered the shutdown of a Highland Lakes gas station where leaking fuel from one or more underground tanks is believed to have seeped into the adjacent groundwater and contaminated several nearby wells.
The leakage, which was discovered more than two weeks ago at the Delta station at the corner of Breakneck and Canistear roads, has prompted authorities to notify property owners there and on nearby Ridge and Wawayanda roads who live or own businesses within a 200-foot radius of the site, as required under the state's Private Well Testing Act.
However, as a precaution, a site remediator is contacting additional property owners with the aim of testing all wells within 500 feet -- an area that could be expanded even farther if wells beyond the initial 200-foot radius are found to have been contaminated, according to James McDonald, director of the Sussex County Division of Health.
"There's a licensed site remediation professional going out and performing analyses on all wells within 500 feet, and individuals that do live within that range are going to be contacted," McDonald said Friday.
At least three nearby wells are believed to have already tested positive for excess concentrations of benzene, a gasoline component whose presence in drinking water has been linked to cancer. Additionally, some neighbors are reportedly concerned that some of the gasoline that has seeped below the water table could find its way into nearby Lake Wanda if it hasn't already done so.
Ken Marsh, owner of the Lake Wanda Store on Canistear Road just across from the station, said he immediately called a DEP hotline upon being notified recently that his well would need to be tested and questioned why the station was still being allowed to operate.
"I told them I wanted to know why they're (the gas station) still being allowed to pump gas if their tanks are leaking," he said.
A contact number for the owner of the station, Surjit Singh, could not immediately be located. However, the station has since been shut pending an investigation, and a tanker truck was at the site last week removing the remaining fuel from its tanks.
Marsh said he immediately began substituting bottled water for the tap water he normally uses in the preparation of coffee, pizza dough and pizza sauce sold at his convenience store after learning more than a week ago that his well had tested positive for benzene, though he said none of his baked goods is made with tap water.
Marsh indicated a second well at a commercial property he owns across the street, where a barber shop and a chiropractor's office are located, and a third well at a neighbor's property had also tested positive for benzene. However, he said it was his understanding that tests at the nearby Highland Lakes Fire Department and Our Lady of Fatima Church had both come up clean.
Manvi Saran -- an environmental scientist and spokesperson for Geo Enviro Remediation Consulting, which is conducting the well testing and remediation -- indicated that for properties where contamination is determined to have come from the gas station, the gas station owner will be responsible through its insurance carrier for paying the costs of both the testing and any remediation, including a carbon filtration system that she said is being recommended for anyone whose well has been affected.
The device -- known as a POET system, or point-of-entry system -- works by filtering out benzene and other harmful contaminants from tap water.
Marsh, who had one of these filtration systems installed at his convenience store on Tuesday, said test results Friday showed it was working 100 percent effectively and that his tap water was now completely free of benzene and other contaminants.
Saran, the site remediator's spokesperson, said the company is continuing to contact property owners within a 500-foot radius of the station to schedule testing of their wells. She said the gas station owner also will be responsible for paying the costs of future quarterly testing of all affected wells until contaminant levels recede below the Environmental Protection Agency's maximum allowable standard, which is 5 parts per billion for benzene.
Marsh, the Lake Wanda Store owner, suggested anyone else who has received a notice, or who is concerned their well may have been affected, contact the remediator. The phone number is 973-610-5404.
"I strongly recommend that you contact the company doing the testing," he said. "The people in charge of doing the remediation will pay for the testing and any filtration system that you may need to have installed."
