Because many regions of the US have had a very tough winter this year, it is possible that spring may bring some problems to septic systems and their owners. The speedy melting of snow and some spring rains, may cause runoff from septic systems, which could contaminate other water sources or areas.

Wastewater and groundwater
Nearly 25 percent of the population in the United States—in more than 25 million homes—disposes of wastewater through onsite, or unsewered, systemsthat return treated effluent to the ground. This is an important public health issue because many of those same homes use wells that rely on groundwater for the drinking water supply. With unsewered systems, homeowners are responsible for treating and maintaining the disposal of wastewater. Most are typically found where centralized wastewater treatment...
Case Study - Groundwater Discharge Permit - Plymouth, Massachusetts
The process of obtaining a groundwater discharge permit for a subdivision scale septic absorption system was faciliated by using the advanced GIS features within EnviroInsite. Geologic features were downloaded and presented at the site scale along with the subdivision boundary and potential downgradient receptors. A cross-section was created showing the detailed soil descriptions, water levels were contoured, and the post-construction water levels shown by superimposing the calculated water table mound.
Septic shouldn’t be a Nightmare for a Dream Home
ProblemIn January of 2002, a couple in Homosassa Springs, Florida (near Orlando) had big plans for large new dream home. They had torn down their old Florida “vernacular” home design, or commonly referred to as the “Cracker Style.” They had major setbacks from the beginning due to the lot size and location; they also began construction without out the proper permits and knowing all that was involved with upgrading their septic system. When they applied for their building permit, they were...
Giardiasis in the United States – an epidemiologic and geospatial analysis of county-level drinking ...
Giardiasis is the most commonly reported intestinal parasitic infection in the United States. Outbreak investigations have implicated poorly maintained private wells, and hypothesized a role for wastewater systems in giardiasis transmission. Surveillance data consistently show geographic variability in reported giardiasis incidence. We explored county-level associations between giardiasis cases, household water and sanitation (1990 census), and US Census division. Using 368,847 reported giardiasis cases (1993–2010)...
Load limit of a UASB fed septic tank-treated domestic wastewater
Performance of a 250 L pilot-scale up-flow anaerobic sludge blanket (UASB) reactor, operated at ambient temperatures, fed septic tank effluents intermittently, was monitored for hydraulic retention time (HRT) from 18 h to 4 h. The total suspended solids (TSS), total chemical oxygen demand (CODT), dissolved chemical oxygen demand (CODdis) and suspended chemical oxygen demand (CODss) removal efficiencies ranged from 20 to 63%, 15 to 56%, 8 to 35% and 22 to 72%, respectively, for the HRT range tested. Above 60% TSS...
