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 realtime 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 nonenforceable 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. The action level for copper is 1.3 mg/l.

Report Key
Ohio EPA Drinking Water Watch
Public Drinking Water Source SW – Surface Water is drawn from lake, reservoir, creek or river; GW – Groundwater is drawn from a well
Violations and Enforcement Actions are shown for the current year
Lead and Copper Test results are shown for the current year if available
Water systems are classified according to rules developed by the U.S. Environmental Protection Agency (EPA) and each state. Water Systems fall into two broad categories: public and nonpublic.
Public water systems are classified as one of the following:
C – Community

Serves at least 15 service connections used by yearround residents or regularly serves 25 yearround residents.

NTNC – NonTransient NonCommunity

Serves at least the same 25 nonresidential individuals during 6 months of the year.

NC – Transient NonCommunity

Regularly serves at least 25 nonresidential individuals (transient) during 60 or more days per year.

This classification is based on information in each of the following five areas:
1.

Quantity and type of population served (e.g., transient, residential).

2.

Number of days served (or annual operating period (i.e., the period(s) of the year that the water system is in operation)).

3.

Number of service connections (i.e., the number of connections for each service area such as commercial, agricultural, residential).

4.

Activity status of the water system (i.e., active, or inactive).

5.

Sources of water (e.g., reservoir, well. Sources of water may be active or inactive depending on whether the source is seasonal or yearround. The current date determines active or inactive status).
