With the Flow Ohio tracks trends in your watershed, posting weekly updates from USGS WaterWatch Current Streamflow and Ohio EPA Division of Drinking and Ground Waters.

USGS WaterWatch Current Streamflow weekly report data is captured from real-time monitoring stations, including the flow volume as a percentage of average (mean), flow volume in cubic feet per second, flow depth, and temperature, where available. A river or stream that has reached flood action stage is shown in bold text, a system in flood stage appears in red, ice affected in italics.

USGS Groundwater Watch – data captured from well sites, including depth (in feet) from ground surface to reach water level; the higher measurement represents lower groundwater level.

Public Drinking Water systems are added to our database each week - active (A) community (C) systems sourced from groundwater or surface water for residential delivery, by watershed. Recent violations and enforcement orders, lead and copper test results as posted in Ohio EPA Drinking Water Watch are included. For more information, see report key at the end of this document.

EPA Lead and Copper Rule

USA Environmental Protection Agency upholds and enforces drinking water for public water systems through the Safe Water Act. Lead can enter the drinking water stream when corrosion occurs in certain types of distribution lines and connections Lead is toxic when consumed and accumulates in the body over time. The effects of lead toxicity may present as stomach upset to brain damage.

WTOH tracks lead and copper test results by watershed, as published by EPA Ohio on their Drinking Water Watch database.

Public Water systems sample and test for lead and copper at customer taps periodically through the year. While there is no safe level of lead in drinking water, and the maximum non-enforceable target for drinking water is set to 0, the EPA requires action steps be taken when more than 10% of customers are found to have 15 parts per billion lead at their taps, or 0.015 mg/l. Action level for copper is 1.3 mg/l.
