Water Treatment in Westmoreland County, PA

Cesare’s Quality Water Solutions, based in Murrysville, provides water testing, whole-house filtration, softening, private-well treatment and drinking-water systems throughout Westmoreland County. Every system is designed around the water source, the test results, the household flow and the plumbing — not a preset equipment package. Call 724-708-8816.

All of it, from the home base in Murrysville: Greensburg, Irwin, North Huntingdon, Jeannette, Latrobe, Ligonier, Export, Delmont, New Stanton, Penn Township, Hempfield Township, Unity Township, Derry and the townships around them. Westmoreland is Cesare’s home county.

Penn State has summarized 808 drinking-water samples submitted from Westmoreland County between July 2007 and June 2025. Manganese was above 0.05 mg/L in 106 of the 405 samples tested, iron above 0.3 mg/L in 65 of 402, total coliform was detected in 419 of 783, and E. coli in 121 of 783. Submitted samples are not a survey of every home, which is why testing your own water is still the first step.

It varies more than people expect. Penn State reports a median hardness of 100.8 mg/L — about 5.9 grains per gallon — among the 400 samples tested, with results running from 0.8 all the way to 1,327.8 mg/L. A county median cannot tell you whether one house needs a softener; the number at your tap can.

It depends on the address. Within the Municipal Authority of Westmoreland County system, the George R. Sweeney plant treats Beaver Run Reservoir water, the Indian Creek plant draws from the upper Youghiogheny River, some communities receive a blend of the two, the McKeesport plant draws from the lower Youghiogheny, and the Ligonier system is fed by North Fork Reservoir. Other utilities serve smaller portions of the county.

Both, on a schedule. MAWC’s own report states that the Indian Creek and George R. Sweeney plants change the disinfection residual from chloramine to free chlorine annually from mid-October to mid-April. Chlorine and chloramine behave differently in carbon filtration, so the current disinfectant should be confirmed before a whole-house system is designed.

It is worth doing when the service line, solder or fixture materials are old or unknown. In Penn State’s Westmoreland submissions, 13 of the 179 first-draw samples tested were above the 0.015 mg/L reference. Lead usually enters at the household plumbing rather than the source, so only a tap test can answer it for a specific home.

They start from different questions. A Westmoreland well usually needs evaluation for iron, manganese, sulfur odor, hardness, pH and bacteria. A municipal home is more often about hardness, chlorine or chloramine, and drinking-water concerns such as lead or PFAS. The right system follows the source and the test, not the label on the water bill.

Pennsylvania DEP recommends testing every year for total coliform bacteria, nitrate, total dissolved solids and pH, through a state-certified drinking-water laboratory. Add iron, manganese and hardness when there is staining or scale, and retest any time the water changes in taste, odor or appearance. A positive bacteria result has its own follow-up path.

A rotten-egg odor usually points to hydrogen sulfide or another sulfur condition, and the source matters. Odor in both hot and cold water tends to come from the well or supply; odor only in hot water often involves the water heater. Iron, manganese and pH shape the fix, so the odor gets measured before it gets treated.

Orange and rust tones usually mean iron; black or dark deposits usually mean manganese. Appearance alone cannot confirm either, because sediment and oxidized particles look similar. A test tells you what is there and how much treatment capacity it takes to remove it.

Yes. Acidic or otherwise corrosive water contributes to blue-green staining and pinhole leaks in copper. Penn State’s Westmoreland samples ranged from pH 2.7 to 9.7, with 113 of 705 tested outside the recommended 6.5 to 8.5 range. pH is only part of corrosion chemistry, so treatment follows the full analysis, not one number.

Sometimes, and sometimes that is exactly the wrong idea. Those conditions interact — concentrations, oxidation needs and household flow decide the order of treatment. Some homes do well with a combined system; harder water needs separate oxidation, filtration, softening or pH-correction stages, in sequence.

A softener removes hardness minerals by ion exchange and produces genuinely soft water. A salt-free conditioner does not remove hardness — it manages scale behavior. Which one fits depends on the measured hardness, the source, what else is in the water, and whether you want true soft water or mainly less scale.

Properly selected filtration can reduce certain PFAS. EPA identifies activated carbon, ion exchange and reverse osmosis among the technologies capable of it, with performance depending on the specific compounds, the water chemistry and maintenance. PFAS should be measured by laboratory testing first, and the finished water verified after treatment is installed.

It depends on what the water actually requires. Source, test results, household flow, plumbing and the number of treatment stages set the installed price — a straightforward hardness problem is a very different job from a well carrying iron, manganese, sulfur and low pH. Cesare’s prices the system after testing, not before.
