Tag: total suspended solids

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. This parameter was at one time called non-filterable residue (NFR), a term that refers to the identical measurement: the dry-weight of particles trapped by a filter, typically of a specified pore size.

The First Line of Defense: Protecting Inlets and Storm Drains

The First Line of Defense: Protecting Inlets and Storm Drains

In stormwater management for both temporary and post-construction measures, inlet and storm drain protection is one of the first lines of defense. It’s also a measure that often works in combination with other best management practices (BMPs) as part of an overall erosion control or stormwater management program.

Techniques for Successful Sediment Control

Techniques for Successful Sediment Control

Siltation in water containment structures is problematic, resulting in the loss of space in tanks and other structures such as reservoirs, ponds, and catch basins. It also increases the cost of treating drinking water, with high loads interfering with coagulation, filtration, and disinfection.

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

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.
