Drinking Water Advisories
Athens County: Athens Public Water System customers on Hillcrest Dr. west of Strathmore Blvd. and Utah Place north of Dalton Ave were impacted by a BWA Wednesday following a water main break and flooding. Athens PWS serves 32725 customers through 5379 metered connections from a groundwater source.
Allen County: Spencerville Village experienced a BWA Monday after a major water leak occurred overnight. According to Village officials, six feet of pipe was replaced and they are working to get the water pressure back up. Spencerville public water system established June 1 1929 serves 2223 residential water customers through 1000 metered connections from groundwater wells.
Knox County: Gambier Village Public Water System issued a system-wide boil advisory following new waterline tie-in to the village distribution system performed Monday. Gambier Village PWS serves 2502 residential customers through 357 metered connections. Groundwater is purchased from Mount Vernon City Public Water System.
HAB Tracker satellite monitoring program of the NOAA National Centers for Coastal Ocean Science
WT follows the movement and growth of harmful algal blooms (HABs) as provided by the satellite monitoring program of the NCCOS for New York's Lake Champlain, Ohio's Lake Erie and Louisiana's Lake Pontchartrain and surrounding area. Interpretation of satellite images is best in clear conditions at wind speed less than 4 mph, where the appearance and extent of HABs is reliably matched to a color scale for concentration. HABs are known to produce algal toxins of concern for raw drinking water sources and recreational water bodies. Plan beach access to avoid HABs and consider carrying a rapid test kit to detect the toxin microcystins.
New York
Lake Champlain's widespread HAB in the northeast appears as a narrow band extending into the open water from the northwest corner of the northeast arm of Lake Champlain, noted having moved off the north shore in the latest image captured July 2. Baie Missisquoi HAB may be partially submerged, we have no wind speed to assure the reliability of the HAB extent. The appearance of the narrow band is of high concentration, matching the color scale for 1.5 million cells per 100 ml. This HAB initially appeared June 25 near the northwest shore of the northeast arm near Domaine Omer-Alix on the Canadian side of the border at a relatively high concentration, around 400 thousand cells per 100 ml. Another HAB report has been confirmed for Lake Champlain at Pointe au Roche in Clinton County, NY. Fifty-five HABs are confirmed for interior NYS water bodies on Thursday afternoon with the first HAB of the season recorded on Putnam Lake and Whitney Point Reservoir. New HAB reports are confirmed on Lake Champlain, Conesus Lake, Wainscott Pond and Agawam Lake. Get the latest NYS HAB report here.
Louisiana: Southeast LA water bodies are captured in a wide angle pass by the Copernicus-Sentinel III satellite, catching Lake Pontchartrain to Black Bay in frame. The latest image was captured July 2 at a surface wind speed 9.3 mph. This latest image is clear with a good view of the southeast LA water bodies. Lake Pontchartrain appears clear of HAB activity again today. South of Morgan City the water is full of HAB activity, over one million cells per 100 ml concentration. Updates are in progress, the latest HAB report for Louisiana is available here.
Ohio: Lake Erie west basin is captured by the NCCOS monitoring satellite, the latest upload taken July 3 at 19.2 mph. The image is mostly cloud obscured, the HAB in North Maumee Bay Michigan shoreline is visible, matching the color scale at 600 thousand cells per 100 ml concentration. The latest Ohio HAB report is available here.
See the North American drainage basin map here, scroll all the way down to see how surface water moves across the continent into the Pacific, Atlantic, Gulf of Mexico and Arctic Oceans. WT Media Group tells the story of water in three countries, Canada, USA and Mexico. See the drinking water advisories, hazardous spills, floods, drought and harmful algal blooms plotted on the maps, as the water flows. Check out the CrimeBox for historic prosecutions under the Clean Water Act, the Safe Drinking Water Act box for details on public drinking water facilities, interviews with the scientists and tech developers on the leading edge of clean water technology here.
As many drinking water facilities are supplied from surface water reservoirs, the streamflow situation is pertinent to both drinking water supply and quality. High flows can stir up sediment and cause turbidity in the reservoirs, requiring additional treatments to render the water potable. Low flow volume is linked to warmer temperatures in the reservoir and can be an issue for water quality where HABs are present. WT tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's watersheds. Check the watershed layer on the map to see the direction of flow and streamflows that may be impacting drinking water today.
USGS Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified.
Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.
