Located in the San Francisco Bay Area, McCampbell Analytical, Inc. (MAI) offers a full range of environmental services including Wet Chemistry, Microbiological and Aquatic Toxicity testing as well as analytical testing services for drinking water, waste water, storm water, metals testing, soil testing, volatile organic compounds (VOC’s) testing, hazardous waste, and food analysis for a ...
Adding to the challenge of BOD treatment are potential confounding factors inherent in testing for BOD concentrations in stormwater samples: a short hold time for BOD samples can complicate sample collection and accurate measurement in the lab; analytical test methods can be expensive, time-consuming, and difficult to QC; and other pollutants in ...
Stormwater runoff pollution is a serious issue that faces almost every urban and suburban environment. ...
” In general sales conversations, we might explain the answer to this question when discussing the strength of stormwater management systems. Through prior testing, we know that our StormTank Module 25 Series can support a substantial load. But we wanted to see how we stack up against other stormwater management systems, so we put them to ...
An integrated management system was developed for the efficient operation of a storm water treatment unit to assist in the management of urban river water quality and flow. The SWMM hydrological model was calibrated and then used to predict the hydrograph and concentration graphs of surface runoff from a storm events based on weather forecasts. These results are used to decide how to operate ...
With all of these options, the EcoVault® is capable of reaching some of the highest quality water treatment levels that are seen in the stormwater remediation industry as tested by the Florida Department of Environmental Protection1. ...
Fitesa, a non-wovens manufacturer in the state of Washington consistently tests stormwater but experienced problems meeting the stormwater standards for zinc and copper discharge. ...
Similar goals are being achieved by Subcommittee C09.27 on Ground Slag through C989 on slag cement, which specifies reusing ground granulated blast-furnace slag in concrete and mortars. Better Stormwater Management through ASTM Standards Another important consideration in sustainable construction is the proper management of stormwater. ...
Concentrations of 6 different heavy metals and total polycyclic aromatic hydrocarbons (PAHs) were determined in stormwater runoff and in the pond water of two Danish wet detention ponds. The pond water samples were analyzed for toxic effects, using the algae Selenastrum capricornutum as a test organism. Stormwater and pond water from a catchment ...
Stormwater ponds have been widely used to control increased volumes and rates of surface runoff resulting from urbanization. ...
Modelling the removal of micropollutants (MPs) in stormwater treatment systems is essential in a context that is characterized by a general lack of measurements. This paper presents an innovative dynamic model for the prediction of the removal of MPs in stormwater treatment systems (Stormwater Treatment Unit model for Micro Pollutants—STUMP). ...
Transfer of class 1 integron-mediated antibiotic resistance genes has been demonstrated under laboratory conditions. However, there is no information concerning the transfer of these genes in an agricultural environment. The present study sought to determine if integron-mediated streptomycin and sulfisoxazole resistance genes could be transferred from Shiga toxin-producing Escherichia coli (STEC) ...
Pond structures as cost-effective "source control" drainage techniques that can be applied to reduce the risk of downstream flooding and to recycle stormwater. There are no widely accepted performance and water quality management data on stormwater ponds, yet there is a need for operation and maintenance guidelines, coupled with data on reliability, economics and ...
