Your well · Smithtown
Smithtown includes Kings Park. Off-mains kitchens still need a well kit.
The publisher sits in Kings Park, a hamlet inside this town. That mailbox is not a lab. If this Smithtown kitchen is off the mains, start with a well kit at the tap you drink.

The town is Smithtown. Kings Park is one hamlet inside it.
The Town of Smithtown is a Suffolk town. Kings Park sits inside it. So do other hamlets that can share a town name on a tax bill and still not share a pipe. Pipedeck publishes from 65 Cedar Street in Kings Park. That is a publisher address. It is not the Town of Smithtown water office, and it is not a place to drop sample bottles.
The useful fact on this URL is narrower than a town seal. Suffolk wells are still possible on Smithtown lots. Some streets have been on a water-district main for years. Some streets never got one. Some lots connected and kept a well in the grass for the lawn. The town name on the envelope does not tell you which of those three you have. The Kings Park hamlet page is a different URL. This page is the town: if the kitchen is off the mains, the first buy is a well kit.
Do not treat the publisher's hamlet as a lab. People search the town, find Cedar Street, and assume bottles belong on that stoop. They do not. The lab kit comes with a slip. The bottles go where the slip says. Cedar Street is legal mail for the site, not a receiving dock for water. Do not mail bottles to Cedar Street even though the hamlet sits inside Smithtown.
A Smithtown kitchen can look like a Nassau kitchen. Same ranch, same sink, same coffee pot. Nassau still has only on the order of a few hundred private wells countywide. Suffolk's water plan still talks about tens of thousands. Smithtown is in Suffolk. That is why a missing water-district bill here is a well until a lab says otherwise, not a trivia question about the publisher's zip code.
St. James, Nesconset, Hauppauge, the Village of the Branch, Head of the Harbor, Nissequogue, and Kings Park can all sit in this town. An office park and a side-street ranch can share a town line and still not share a main. Walk this lot. Do not borrow a result from a hamlet page because the mailbox happens to be in Kings Park.
How to tell if this Smithtown house is still on a well
Walk the grass. A low round cap is the usual outdoor tell. Then look for a pump and a pressure tank — basement, crawl, or a small well house. Then look at the bills. A regular water-district bill for this address usually means the kitchen already sits on a main. No water-district bill, plus a pump that kicks on at night, usually means a well. Suffolk wells are possible in this town. They are not automatic. The cap and the bill settle it.
If you just closed, ask for the last water bill and walk the yard that week. Closing papers can name a well and still skip the two chemicals this kit is for. If you grew up in the house, you already know the sound of that pump. If you rent, ask who pays for water and whether there is a cap. Silence is still a well until a lab. A landlord who cannot produce a district bill is describing a well house until proven otherwise.
Do not copy the next driveway. Smithtown streets can mix. The house that shares a hedge can pay a district while yours still draws from the yard. A neighbor's tap is not your pipe. A hydrant on the corner is not a kitchen result. A friend in Kings Park who already hooked up is not a result for a Nesconset ranch that never did. The sample is this kitchen.
If the well only waters the lawn and the kitchen already sits on a treated district line, skip this kit. Use the tap-water guide for what you actually drink. If people still drink, cook, and make coffee from the well, order the bottles. Coffee, cooking, and the glasses on the table are the sample. A sprinkler well is not that sample. Kids' glasses from the same tap are the reason to send bottles, not the lawn.
The county panel, the lab kit, and a mailbox that is not either
People type “well test Smithtown” and get three different products. They are not interchangeable. The publisher being in Kings Park does not merge them.
The mail-in lab kit is the one that looks for PFAS and 1,4-dioxane. That is the useful first step if this Smithtown house is off the mains. You order it from the button on this page. You fill the bottles at the cold kitchen tap. You send them to the lab named on the slip. Follow the kit. Do not wash the bottles with soap. Do not sample the hot side. Do not fill from a garden hose or an outdoor faucet you never use for coffee. Pack them the same day if you can. One kit covers the house. Two glasses on one tap do not need two boxes.
Suffolk still sells a $100 private-well test. Call 631-852-5810 if you want that cheaper county check. It is a real lab. 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 panel. Order a kit if you want the chemicals New York now limits at the tap. There is no public phone at Pipedeck. Do not call the county number expecting this publisher.
A hardware-store strip is narrower still. 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. Clear water is not a result. Taste is not a result. A relative who never had a complaint is not a result. Iron, sulfur, and hardness can stain a sink. Those are real well complaints. They are not a PFAS reading.
Do not mail bottles to Cedar Street. The publisher is Kings Park. The address is 65 Cedar Street, Kings Park, NY 11754. That line is the NAP on this site. It is not a bottle drop, not a county window, and not a place to ship a kit because the hamlet sits inside Smithtown. Legal correspondence for Pipedeck is on the contact page. Water bottles are not that correspondence. The county well office is not on Cedar Street either.
After the report — do not paste another town onto this tap
Read the report at the table. If PFAS is high, get a filter made for that chemical. The marks to look for are NSF 53 and P473. Reverse osmosis also covers them. A mystery jug in the fridge that only says it filters water usually does not. Test first, then buy. Buying the box first is how a pitcher ends up in the fridge and the well stays the well. That shopping trip is the PFAS filter guide. Cartridges are a later yearly cost. A one-time rebate does not buy next year. That later bill lives on the replacements page, after a system exists.
If the report shows 1,4-dioxane, a fridge pitcher does not remove it. An under-sink reverse-osmosis system is the usual treatment after a high result. That is a different job from a carbon jug. The 1,4-dioxane reverse-osmosis guide is that next step. This page is still the test, because you should know what is in the well before you buy a system. 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 does not mean the well is clear of it.
Do not paste another hamlet onto this kitchen. Mattituck is a North Fork well story with its own sampling. Calverton sits near an old plant with a different groundwater file. Medford is a mixed Brookhaven street. Bethpage is mostly public supply. Hempstead is a Nassau district tap. None of those pages is a Smithtown result. The Town of Smithtown can hold a well and a main on the same block. The only bottles that name this tap are the bottles you fill here.
If a water-district bill already shows up and the kitchen drinks that tap, skip this kit. Start with the tap guides. A Smithtown ranch without a water bill is still a Suffolk well job. Same-looking kitchen, different next step. Bottled water is a stopgap while you wait on a system. It is not the house fix. Retest after well work, or when you want a new baseline. The county-wide map lives on the Suffolk wells page. This URL is the town that contains Kings Park, and the rule that off-mains kitchens here still need their own kit.

Common questions
Is Kings Park in Smithtown?
Yes. Kings Park is a hamlet in the Town of Smithtown, Suffolk. Pipedeck publishes from 65 Cedar Street there. The well kit is still for the kitchen that is off the mains, not for that stoop.
Should I send well bottles to 65 Cedar Street?
No. Do not mail bottles to Cedar Street. Send them to the lab named on the kit. Cedar Street is Pipedeck's legal address, not a drop-off.
Does every Smithtown house need a well kit?
No. Suffolk wells are possible here, not guaranteed. If this kitchen already sits on a water-district main, skip the kit and use the tap guides. If you are off the mains, order the kit.
Is Pipedeck the Town of Smithtown or the county well office?
No. The publisher is Kings Park. The county $100 test is 631-852-5810. This site is not that office and not the town water desk.
What if the Smithtown well test comes back high?
Match the chemical. NSF 53 or P473, or reverse osmosis, for PFAS. Reverse osmosis for 1,4-dioxane. A fridge pitcher is not automatically that filter.
Will a hardware-store strip find PFAS or 1,4-dioxane on a Smithtown well?
No. Those strips are built for chlorine, hardness, and a few metals on a color chart. PFAS and 1,4-dioxane need a lab kit from the kitchen tap.
My Smithtown neighbor is on public water. Do I still test?
Yes, if this kitchen still draws from a well. Mixed streets exist inside the town. A neighbor's water bill is not your pipe.
How do I sample a Smithtown kitchen tap?
Use the cold tap you drink from. Do not wash the bottles with soap. Do not fill from a hose. Pack the same day if you can. One kit covers the house. Do not send the bottles to Cedar Street.
