How the water is treated

Old Straitsville-rockbridge buys water that Logan, City Of treats first, so the steps that count are the seller's. EPA's treatment table registers these steps for Logan, City Of: aeration, corrosion control, cartridge filtration, coagulation and settling, chlorine disinfection, dechlorination, iron and manganese removal, fluoridation, reverse osmosis, and sand or media filtration.

Old Straitsville-rockbridge adds nothing of its own on that table.

The list is what each system registered with EPA for treatment plants EPA still shows as active, and it can lag a plant upgrade.

Lead and copper at the tap

In the sampling period ending December 2025, the 90th-percentile lead result at Old Straitsville-rockbridge was 0 ppb, under both the current 15 ppb action level and the 10 ppb level that applies from 2027. A result of 0 means at least nine in ten of the homes sampled had no lead detected.

The highest result on file is 2.3 ppb, in the period ending December 2017.

EPA has 5 sampling periods on file for Old Straitsville-rockbridge since 2016, the first ending in 2017; no period was above 10 ppb.

Every water system has to inventory its service lines, the pipes from the main to each building. In the inventory Old Straitsville-rockbridge sent EPA, 176 lines are counted.

Systems sample taps in the homes most likely to have lead pipes or solder. The 90th-percentile result is the level nine in ten of the sampled homes were at or below. Lead comes mostly from service lines and house plumbing, not the source water, so a low result for the system does not clear an old house.

EPA's dashboard status for this inventory: reported all required service line types.

PFAS

The water Old Straitsville-rockbridge buys is treated by Logan, City Of, so the results below are Logan, City Of's.

EPA's fifth national round of testing (UCMR 5) took 2 samples of the water entering the pipes of Logan, City Of in 2024 and measured 29 PFAS. No PFAS was detected, PFOA and PFOS (federal limit 4 ng/L each) among them.

Ohio EPA's own statewide sampling tested 1 plant of Logan, City Of (latest sample September 2020). Not one of the six PFAS tested (PFOA, PFOS, PFHxS, PFNA, GenX and PFBS) was detected.

PFAS are the 'forever chemicals' from firefighting foam, plating shops and non-stick coatings. Results are for water leaving the plant, not your tap.

Disinfection byproducts

Chlorine that disinfects water also reacts with organic matter to form byproducts. Two groups have federal limits: total trihalomethanes (TTHM, 80 µg/L) and five haloacetic acids (HAA5, 60 µg/L), judged on running yearly averages at each sampling site.

For TTHM, the average of Old Straitsville-rockbridge's samples in 2019, the last year it was sampled, was 37.6 µg/L. The worst yearly average was 64 µg/L and the highest single sample was 64 µg/L, from 7 samples taken from 2013 to 2019.

For HAA5, the average in the last year sampled was 7.2 µg/L. The worst yearly average was 14 µg/L and the highest single sample was 14 µg/L, from 7 samples.

A yearly average of 0 means nothing was detected in that year's samples. EPA's file stops at 2019; Ohio EPA's Drinking Water Watch has newer results.

Nitrate, arsenic and radioactivity

The water Old Straitsville-rockbridge buys is treated by Logan, City Of, so the results below are Logan, City Of's.

Nitrate: the highest of 9 samples was 0.47 mg/L (as nitrogen) in 2018; in 2019, the last year sampled, nitrate was not detected. No sample was over the limit of 10 mg/L. Nitrate above 10 is unsafe for infants.

Arsenic: the highest of 33 samples was 7.6 µg/L (limit 10); detections averaged 7.6; none over the limit.

Measured in finished water: at the plant's entry points and in the distribution system; raw well and intake samples are left out. Non-detects count as zero.

Solvents and fuels

The water Old Straitsville-rockbridge buys is treated by Logan, City Of, so the results below are Logan, City Of's.

EPA's file holds results for all six solvent and fuel compounds it checked. Benzene, carbon tetrachloride, 1,2-dichloroethane, trichloroethylene, tetrachloroethylene, and vinyl chloride were not detected in 3 samples each.

"Not detected" means the lab's result was below what its method can measure, not that the compound is absent. Non-detects count as zero in the highest-result column.

Farm chemicals and metals

The water Old Straitsville-rockbridge buys is treated by Logan, City Of, so the results below are Logan, City Of's.

EPA's file holds results for 8 of the nine herbicides and metals it checked. Detected: barium in 4 of 4 samples, highest 64.5 µg/L (limit 2,000); mercury in 2 of 3 samples, highest 0.6 µg/L (limit 2). Not detected: atrazine, alachlor, chromium, cadmium, selenium, and thallium, in 3 samples each.

Non-detects count as zero in the highest-result column.

Bacteria in the pipes

From 2012 to 2019, 0 of 92 routine total coliform samples taken in the distribution system at Old Straitsville-rockbridge tested positive (0%); in 2019, the last year on file, 0 of 12 did.

A positive coliform test is a warning sign, not a violation by itself. E. coli is a sign that human or animal waste may have reached the water. Coliform counts are routine samples only; E. coli counts include repeat samples.

Fluoride

The Ohio Department of Health's report to the CDC (My Water's Fluoride) says Old Straitsville-rockbridge buys its water from Logan, City Of, a system that adjusts the fluoride level to the recommended level for preventing tooth decay.

EPA's treatment table lists fluoridation among the steps at Logan, City Of, which treats the water Old Straitsville-rockbridge buys.

Measured fluoride: 1 mg/L on average leaving the plants of Logan, City Of, which supplies Old Straitsville-rockbridge, in 2019 (in the range dentists aim for); samples ran from 0.69 to 1.16 mg/L across 101 samples in 2012 to 2019.

The recommended level for preventing tooth decay is 0.7 mg/L; the federal limit is 4 mg/L. The treatment list is what each system registered with EPA and can lag a plant upgrade.

Lithium

Lithium was not detected in 2 UCMR 5 samples at Logan, City Of, which supplies Old Straitsville-rockbridge, last sampled in 2024 (the method reports from 9 µg/L).

Lithium is not regulated. EPA's draft health reference level is 10 µg/L, and it occurs naturally in deep groundwater, so well systems in the northwest run highest.

How well the service area is mapped

EPA estimated the service area of Old Straitsville-rockbridge with a computer model rather than drawing it from the utility's map, so its edges are approximate.
