Tag: TSS

Total suspended solids (TSS) is a water quality parameter used for example to assess the quality of wastewater after treatment in a wastewater treatment plant. It is listed as a conventional pollutant in the U.S. Clean Water Act.

Twenty Years of Stormwater Samples

Twenty Years of Stormwater Samples

Nest Environmental Services has accumulated more than 1,000 stormwater samples and analysis, at the rate of 50 to 60 samples per year, for over 20 years. We thought it would be instructive to look at the results of that monitoring to see whether there was any long-term trend in the

Editor’s Comments: We Know What’s in the Water

You might think of this issue as the magazine’s sample case. Decades ago, sales reps ­traveled the country lugging heavy suitcases full of carpet swatches or wall coverings or even miniature models of farm machinery and equipment. Here, in a much easier-to-carry package, are some samples of—well, sampling equipment, which

Storm Drain Inlet Protection

Storm Drain Inlet Protection

If a stream or other waterbody is showing an increase in sediment or pollutant contamination, nearby active construction sites are usually the first suspect. As any developer or construction crew chief knows, devices to stop runoff from the site are an absolute necessity.

Underground Stormwater Storage Case Studies

Underground Stormwater Storage Case Studies

Underground retention and detention systems continue to increase in popularity as urban and suburban infill prompts careful consideration of proposed land uses on high-value real estate. Placing stormwater management underground frees up space for higher value land uses and greater return on investment. Additionally, trends toward water awareness and reclamation,

Catching Up

Catching Up

In the 1940s, two former music hall entertainers, Marcel and Nelly Tilloy, purchased an estate in France’s Rhône ­Valley, and by 1952 they had created Relais and Châteaux, with eight hotels and restaurants between Paris and the French Riviera. Today, the association has more than 520 partners around the world.

The Nutrient Separating Baffle Box: A Key to Trapping Pollutants

A Florida Park Revitalized
Kissimmee Lakefront Park in Kissimmee, FL, desperately needed revitalization. New facilities and buildings were planned and built, and paved surfaces were restored. Another big part of the project was installation of stormwater treatment best management practices (BMPs).

The park covers about 25 acres, situated between the downtown urban

Comparing Volumetric and Gravimetric Suspended Sediment Concentration Data From a Midwest Stream

Comparing Volumetric and Gravimetric Suspended Sediment Concentration Data From a Midwest Stream

The ability to categorize suspended sediment metrics (e.g., total concentration, mean particle size, particle size class) to specific land-use types is increasingly appealing in terms of better targeting mitigation strategies. However, innovative real-time in situ instruments that advance monitoring capabilities often provide results that are not readily comparable to traditional
