About this area's water

Did you know
- RLCWA doesn't treat a drop of its own water -- every gallon is purchased pre-treated from three separate utilities and blended before it reaches a customer's tap.
- The New London Reservoir covers 220 acres and holds 1.4 billion gallons when full, fed by Buck Creek, a branch of the Vermilion River.
- Ashland's 12 supply wells tap the Jerome Fork basin at depths ranging from just 70 feet down to 300 feet.
- In 2023 RLCWA delivered an average of 5,744,491 gallons of drinking water a day -- all of it bought from someone else.
History5
- 2014City of Ashland's radium sample (0.189 pCi/L) collected -- the oldest result still carried forward in RLCWA's 2023 CCR table.
- 2016The federal Revised Total Coliform Rule took effect on April 1, changing how RLCWA and its sellers monitor for coliform bacteria.
- 2018Last radium and alpha-emitter samples on record for the New London source: radium 1.04 pCi/L and alpha emitters 5.4 pCi/L, both under their MCLs.
- 2020New London and Ashland were sampled for six PFAS compounds under Ohio's statewide PFAS initiative; none were detected in finished water.
- 2023RLCWA failed to collect corrosion-control water quality parameter samples at the Ohio EPA-required frequency in July-December, triggering a public notice.
Treatment & pressure
How it is treated
RLCWA operates no treatment plant; it blends finished water from three sellers: Avon Lake Regional Water (Lake Erie), the Village of New London (New London Reservoir, fed by Buck Creek) and the City of Ashland (12 Jerome Fork wells). All three filter and disinfect.
Water pressure
Not published; no service pressure or pressure-zone figures appear in the 2023 CCR.
What it costs
Not found in the sources reviewed; RLCWA's 2023 CCR does not publish a residential rate schedule.

EPA compliance record · Avon Lake City (treats the water)
Lead at the tap: 90th-percentile result 0 ppb in 2025 (action level 15 ppb).
EPA record: no health-based violations since 2015.
1 violation of any kind logged since 2020, 1 of them paperwork (monitoring, reporting, public notice or consumer report).
Supply stress
No source of its own -- RLCWA depends entirely on three sellers. Ohio EPA found no direct pollution source for Avon Lake's Lake Erie intake; New London's reservoir sees soil-runoff turbidity; and Ashland's Jerome Fork wellfield is rated 'high susceptibility' for thin clay cover and a shallow water table.
Sewers
Sanitary
Not addressed in RLCWA's CCR. RLCWA is a water-only authority distributing purchased water across rural Lorain and Huron county communities; nothing in the sources reviewed shows it operating sanitary sewers.
Storm
Not addressed in any source reviewed.
