Protect Your Groundwater Day – September 9, 2014.
9/9/2014 -- Of all the usable freshwater on Earth, 99 percent is stored in underground aquifers. Even if you get your drinking water from a reservoir, most surface-water bodies are connected to groundwater through the hydrologic cycle. Protect groundwater by keeping it safe from contamination, and use it wisely. More information on groundwater and Protect Your Groundwater Day can be found at the National Ground Water Association and USGS Groundwater Information Pages.
Monitoring Quantity And Quality Of Water.
9/2/2014 -- You can’t manage what you don’t measure. In the Scioto Watershed, two new streamgages in Columbus and an updated streamgage including a new rain gage in flood-prone LaRue will be part of new flood-warning systems to help both municipalities better prepare and plan for floods. In the Maumee Watershed, four new streamgages and seven new automatic water-quality samplers were installed. These automatic samplers can be programmed to collect water-quality samples at predetermined time intervals or when certain water-level and discharge thresholds are reached; data from the analyzed samples will be used to quantify the daily, seasonal, and annual nutrient and sediment loads. Increased knowledge of a stream’s water quality can lead to more effective resource management, including decisions on drinking-water treatment and recreational uses, and assessment of aquatic habitat.
Before Swimming Or Paddling, Check The Water Quality.
6/18/2014 -- Each morning, beach managers post advisories stating whether water quality at the beach is predicted to be poor or good that day based on the Ohio Nowcast. Nowcasts predict whether E. coli bacterial levels in the water are within the water quality standard and acceptable for swimming. Nowcasts are based on real-time beach specific variables such as turbidity (cloudiness of the water), recent rainfall, and wind conditions. Traditional analytical method takes 18-24 hours to complete and can lead to erroneous assessments of public-health risk because it relies on “yesterday’s” E. coli and water quality conditions may have changed. As described in a recent USGS report, nowcasts are being developed or improved at over 40 beaches around the Great Lakes. Safe swimming!
