Road Salt in Burlington County Well Water: Signs, Testing and Treatment

Road salt can get into private wells in Burlington County, and the first signs are usually a salty or brackish taste, faster corrosion of pipes and fixtures, or a water test showing high sodium or chloride. Salt spread on roads, driveways and parking lots dissolves into meltwater, soaks into the sandy soil and can reach shallow wells near busy roads. New Jersey’s recommended upper limit is 250 mg/L for chloride and 50 mg/L for sodium. If your test shows levels above those, a reverse osmosis system at the kitchen sink is the usual fix for drinking and cooking water. A water softener will not remove it.

How Road Salt Gets Into a Well

Most road salt is sodium chloride, the same chemical as table salt. The U.S. Geological Survey calls road salt a major human source of chloride in surface water and groundwater. It notes that road salt use in the United States has tripled since the 1970s, while other uses of salt have stayed flat or gone down.

When snow and ice melt, the salt dissolves and travels with the water. Some runs off into ditches and streams. The rest soaks into the ground. Much of Burlington County sits on sandy Coastal Plain soil that drains fast. That is good for septic systems and farm fields, but it also means dissolved salt can move down to the water table without much in the way. Shallow wells, older wells with short casings and wells close to a road, a salted driveway or a commercial parking lot face the highest risk.

Salt also builds up over time. Groundwater moves slowly, so salt from many winters can collect in the aquifer and keep coming out for years. That is why a well can test fine one year and high a few years later, even though the road has been salted the same way all along.

Signs Your Well Has a Salt Problem

You may not notice anything at low levels. As sodium and chloride rise, these are the common clues:

• Salty or brackish taste, often worse in late winter and early spring after a lot of snow and salt
• Corrosion: pinhole leaks in copper pipe, blue-green stains, pitted faucet parts or water heaters that wear out early
• White crust on fixtures and glassware that does not act like ordinary hardness scale
• Coffee or tea that tastes off even with fresh grounds
• Plants or a garden bed that struggle when watered from the well

None of these proves road salt by itself. A softener that is overfilling its brine tank, seawater moving into coastal aquifers, or septic effluent can cause some of the same signs. A lab test is the only way to know.

What the Numbers Mean

New Jersey sets recommended upper limits for how water looks, tastes and behaves in your plumbing. Under N.J.A.C. 7:10-7.2, they are:

• Chloride: 250 mg/L
• Sodium: 50 mg/L
• Total dissolved solids (TDS): 500 mg/L
• Hardness: 250 mg/L as calcium carbonate

The EPA’s secondary standards use the same 250 mg/L for chloride and 500 mg/L for TDS, and list salty taste, corrosion and staining as the effects. These are guideline levels, not health-based limits. Still, they matter for two reasons. First, anyone on a sodium-restricted diet should talk with their doctor about the sodium in their water. Second, salty water is more corrosive, so it can pull metals such as copper and lead out of household plumbing.

The Radium Connection

There is one more reason to take salt in South Jersey wells seriously. A USGS study of the Kirkwood-Cohansey aquifer in southern New Jersey found that radium levels in a network of 25 drinking water wells rose over about a decade, and the increases were linked to road salt use. The largest increases were in acidic groundwater, which is common in Burlington County. The extra sodium appears to push radium off the sediments and into the water. If your well tests high for salt, also ask about gross alpha and radium. Our guide to radium in South Jersey well water explains that testing.

Testing Your Well for Sodium and Chloride

Ask a New Jersey certified lab for sodium, chloride, TDS, pH and hardness. Add copper and lead if you have copper plumbing or see blue-green stains. Some practical tips:

1. Test in late winter or early spring. Levels often peak after the snow season, so a sample taken then shows the worst case.
2. Sample before any treatment. If you have a softener, take the sample from an outside spigot or a tap that bypasses it. Softened water always reads higher in sodium.
3. Keep the results. A test every year or two shows whether levels are steady or climbing, which helps you decide how far to go with treatment.
4. Test after big changes nearby, such as a road widening, a new parking lot or a new salt storage area.

Our free in-home water analysis gives you a quick first look at hardness, TDS, pH and iron, and tells you whether a full lab panel makes sense.

Treatment Options That Work

Reverse Osmosis for Drinking and Cooking Water

A point-of-use reverse osmosis system under the kitchen sink is the standard answer for sodium and chloride. It pushes water through a very fine membrane that holds back most dissolved salts. The result is clean-tasting water for drinking, cooking, coffee, ice and pets. Because the problem is dissolved salt, ordinary carbon or sediment filters will not help.

Why a Water Softener Will Not Fix It

This trips up a lot of homeowners. A water softener trades hardness minerals for sodium, so softened water has more sodium in it, not less. If your water is both hard and salty, the softener still has a job protecting the plumbing and water heater. Just pair it with reverse osmosis at the kitchen sink, and test the raw water before the softener when you check for road salt.

Protecting the Plumbing

High chloride makes water more corrosive. If your water is also acidic, an acid neutralizer can raise the pH and slow corrosion of copper pipes. When chloride is very high throughout the house, a whole-house reverse osmosis system is possible, but it is a bigger project with a storage tank and a booster pump. We only recommend it when the test results call for it.

Prevention Around Your Own Property

You cannot control the town or state plows, but you can cut the salt that lands near your own well:

• Shovel early so you need less melt product.
• Use sand or grit for traction on the driveway near the wellhead.
• Never pile plowed snow on top of or uphill from the well.
• Store bags of rock salt in a covered spot well away from the well.
• Make sure the well cap is tight and the casing sticks up above the ground, so meltwater cannot run straight down the outside of the casing.

If a new well is ever drilled, ask the driller about placing it as far from the road as the lot allows and casing it into a deeper water-bearing zone.

Burlington County Wells Near Busy Roads

Burlington County has thousands of homes on private wells in towns like Medford, Southampton, Tabernacle, Shamong, Pemberton, Lumberton, Mansfield, Springfield and parts of Evesham. Many sit along heavily salted roads such as Route 70, Route 206, Route 38 and Route 73, or near the I-295 and New Jersey Turnpike corridors. Homes in the Pinelands parts of the county often have acidic water too, which makes the corrosion and radium questions more important.

We test in your home for free, explain the results in plain language and recommend only what the water needs. Call 1-888-577-8088.

Frequently Asked Questions

Can road salt really get into a private well?

Yes. Road salt dissolves in meltwater and soaks into the ground, and the USGS identifies it as a major source of chloride in groundwater. Shallow wells near salted roads, driveways and parking lots are most at risk.

What levels of sodium and chloride are too high?

New Jersey's recommended upper limits are 250 mg/L for chloride and 50 mg/L for sodium. They are taste and corrosion guidelines rather than health limits, but people on sodium-restricted diets should talk with their doctor about sodium in their water.

Will a water softener remove road salt from my well water?

No. A softener adds sodium while it removes hardness. Reverse osmosis at the kitchen sink is the usual treatment for sodium and chloride in drinking water.

When is the best time to test for road salt?

Late winter or early spring, after the snow season, when levels are often highest. Take the sample before any softener.

Is salty well water bad for my plumbing?

It can be. Water high in chloride is more corrosive and can shorten the life of copper pipes, fixtures and water heaters, and can pull copper and lead from plumbing.
