North Fork · Southold
Southold NY still drinks private wells. Ticks sit in the same grass.
The Town of Southold is the North Fork. Kitchens off the mains need a lab kit, the way Mattituck does. Field edges need permethrin on clothes, the way the East End does. Those are two hops. Do not splice them.

The town is not Mattituck's sample
Southold is the North Fork town. It runs from the Mattituck and Laurel side, through Cutchogue, New Suffolk, and Peconic, through the Southold hamlet, past Greenport, and out to East Marion and Orient. Long Island Sound is one shore. Peconic Bay is the other. That is not the South Fork, and it is not a Nassau water-district cartoon.
Mattituck is a hamlet inside this town. That hamlet has its own URL because a sample there found 20 of 38 private wells over New York's PFAS limit, some about sixty times over. That fraction is a Mattituck kitchen fact. It is not a census of Cutchogue. It is not a Greenport village tap. It is not Orient by default. The well on this lot is the only well a kit can name.
Suffolk's water plan still cites about 45,000 private wells countywide, on the order of 200,000 people. That is a plan figure, not a door-to-door count of this town. Nassau has on the order of a few hundred private wells. A Southold farm lane is in the Suffolk world. A Hempstead kitchen is usually on a main. Do not copy a Nassau plant number onto a North Fork kettle. Do not copy Calverton's Navy/Grumman site figures onto a Southold street. Calverton is a named site in the Town of Riverhead. Riverhead is the fork. This town is the north fork past that fork.
Some Southold lots never joined a public water main. Some village blocks did. Mixed streets exist here the same way they exist in other Suffolk towns, just with more field and more houses that sit dark until Friday. If a water-district bill never arrives, treat the kitchen as a well until a lab says otherwise. If the kitchen is already on a district, skip this kit and use the PFAS and 1,4-dioxane tap guides. The county-wide well guide lives on the Suffolk wells page. This URL is the Town of Southold.
Cap, pump, or a water-district bill
Start outside. Look for a round well cap in the lawn, often close to the house, sometimes in a patch the mower skips. Then look in a basement, a crawl, or a small well house for a pump and a pressure tank. Then look at the bills. A regular Suffolk County Water Authority bill usually means this kitchen is on public water. No water-district bill, plus a pump, usually means a well. Do not guess from the next driveway. One lot on a Greenport side street can pay a district. The next lot, toward a field, can still drink the sand.
If you just bought, ask for the last water bill and walk the grass that week. Closing papers can name a well and still skip the two chemicals this kit is for. If you rent, ask who pays the water and whether there is a cap. Silence is still a well until a lab. If you only open the house from Friday to Sunday, the dark weekday does not put a plant on the pipe. A North Fork weekend kitchen is still a kitchen if anyone drinks.
Some lots keep a well for irrigation after the kitchen connects. If people still drink, cook, and make coffee from that well, this kit is the job. If the well only waters vines or a lawn, and the kettle is on a district, skip the kit. Kids' glasses from the same tap are the reason to fill bottles, not the sprinkler.
New York limits two common PFAS — PFOA and PFOS — at 10 parts per trillion in drinking water. You will not taste that. You will not smell it. A clear glass on a Southold counter is not a PFAS test. From 2016 through 2022, Suffolk sampled private wells. About 47% of those sampled wells showed some PFAS. Two hundred two were over drinking-water standards. That is the wells they sampled, not a score for every Southold street. Your kitchen still needs its own bottles.
Suffolk still sells a $100 private-well test. Call 631-852-5810 if you want that product. It is a real lab. It is cheap. It looks at bacteria, nitrates, and the metals people have asked the county about for years. It does not look for PFAS. It does not look for 1,4-dioxane. This site is not that office. Keep their test if you want their check. Order a kit if you want the chemicals New York now limits at the tap. A twelve-dollar hardware-store strip is even narrower. It is built for chlorine, hardness, and a few metals you match to a color chart. It will not find PFAS. It will not find 1,4-dioxane. A water softener treats hardness. It does not close this gap.
When the kit arrives, use the cold kitchen tap you actually drink from. Do not wash the bottles with soap. Do not sample the hot side. Do not fill from a garden hose, a dock hose, or an outdoor shower. Pack the same day if you can. One kit covers the house. Two glasses on one tap do not need two boxes. If PFAS comes back high, shop NSF 53 or P473, or reverse osmosis. If 1,4-dioxane is high, reverse osmosis — not a pitcher. Test first, then buy. The filter pages are next. The measurement belongs here.
Ticks on this fork sit in the same grass
The second hop on a Southold lot is not water. Ticks sit in grass, leaf litter, and the seam where a mowed strip meets a field, a hedge, or a wood line. That is the East End picture. East Hampton, Montauk, and Shelter Island get the same ecology. The North Fork puts farm, vineyard, and Sound-side brush in the same glance. A Southold lot that meets a field is enough. You do not need a preserve. Taking out the trash past the mowed middle, cutting through toward the water, or reaching into taller stuff for a hose is the minute the cuff is for.
Permethrin goes on clothes — pants, socks, the outside of shoes. Spray the fabric, let it dry, then dress. Do not put clothing permethrin on skin. Skin bug spray is a different product, for bare arms and neck. A yard fogger stays on that lot. It does not ride a pant cuff to a farm stand, a trail verge, or someone else's hedge. Clothes first. Factory-treated fabric lasts through more laundry; until that is the button, the hop is the bottle you put on clothes you already own. Keep cats away from wet spray and drying fabric.
This is not Superfund. The island has 34 federal plus 449 state listed sites. Those are a different list. A tick in the grass is not a plume. Do not hang a filter on a pant cuff. Do not hang a well kit on a tick. The longer clothes page is the East End ticks guide. The button here is that hop, separate from the kit.
Two hops. Do not splice.
A lab kit names the tap. Permethrin treats the clothes. They can sit on the same Southold lot in the same week. They are not one SKU. Do not buy a pitcher because the town name was in a headline. Do not skip the kit because you sprayed pants. Do not skip the clothes because the well report was clean. Sorting is the job of this URL.
The default button on this page is the well kit, because the first question for a North Fork kitchen is still whether the glass is a well. If it is, measure. If the kitchen is on a district, leave the kit and keep the clothes hop if you walk the hedge. Weekend guests in sneakers still walk someone else's seam. Treated pants do not name PFOA. A certified lab does not cover a sock line.
Mattituck keeps its own bottles and its own 20 of 38. Riverhead keeps Calverton. East Hampton keeps a ticks-first page. This URL is the Town of Southold: kit for the well, permethrin for the walk, each on its own button. About three-quarters of Suffolk homes are still on a septic tank or cesspool. The well and the tank often sit on the same sand. Nobody is treating that drinking water on the way in. The sand under the island is a sole-source aquifer. The useful step at this house is still a kit if you have a well, and treated clothes if you walk the edge.

Common questions
Is this the Mattituck well page?
No. Mattituck is a hamlet inside the Town of Southold and keeps its own URL. The 20 of 38 PFAS sample stays there. This page is the town: a lab kit if the kitchen drinks a well, permethrin on clothes if you walk the grass.
Does every Southold house drink a private well?
No. Some village blocks sit on a water district. Some farm lanes never got a main. No water-district bill plus a cap or a pump usually means a well. A neighbor's tap is not your pipe.
Should I put permethrin on the well or in a filter?
No. Permethrin is a clothes treatment for pants and socks. It is not a water chemical and it is not a filter. The well hop is a lab kit at the kitchen tap.
Is Suffolk's $100 well test this kit?
No. Call 631-852-5810 if you want the county panel. It looks at different things. It does not look for PFAS or 1,4-dioxane. Pipedeck is not that office. The button on this page is a lab kit you send from the tap.
We only open a Southold house on weekends. Do we still test the well?
If anyone drinks the well when the house is open, treat it as a drinking well. A dark weekday does not put a plant on the pipe. Fill bottles at the cold kitchen tap on a day you are there.
Can I fill the bottles at an outdoor shower?
No. Use the cold kitchen tap you actually drink from. An outdoor shower, a dock hose, and a garden hose are the wrong sample. Do not run the hot side.
Are North Fork ticks a Superfund or tap problem?
No. Ticks sit in grass and at the field edge, the same East End ecology as the South Fork. Listed industrial sites are a different list. A private well is a lab kit. The clothes hop is permethrin.
If the well report comes back high, what do I buy?
Match the chemical. NSF 53 or P473, or reverse osmosis, for PFAS. Reverse osmosis for 1,4-dioxane. A fridge pitcher is not that filter. Test first, then buy. Permethrin still does not replace the kit.
