Many thanks to ALGA (Australian Land and Water Group and Michal) for providing the recent seminar on using Willowstick for high resolution groundwater flow modelling, presented by the good folks at Hydroterra. As a former geophysicist (humping back packs of gear across mine sites and glacial flows alike) I enjoyed both the summary on geophysical

As a young man, I didn’t know what I wanted to do, from computer engineering switching over to what I thought was an outdoors focussed Environmental Science degree, and a little bit of volunteer work in ecological assessments. But I really cut my environmental teeth in the Persian Gulf on an unplanned opportunity via a

The Little Bushy Warren waste collection site is used for the gathering of green garden waste for Hampshire. The green waste is composted in windrows, and turned into soil and lawn conditioners, woodchip mulch or pine bark. Two lagoons collect rainwater runoff from a four hectare hard-standing area for the compost windrows. Veolia asked for

A reed bed was designed and installed for the treatment of kitchen waste water and grease coupled with hydrocarbon contaminants from petrol filling area runoff in Raunds, United Kingdom. The wastewater treatment system is still in use, and its performance is conforming to all guidelines and limits set. Reed bed systems represent excellent innovation for

The wastewater was highly contaminated with amines and phenols (COD up to 5000mg/l). The facility used a batch processing method, which meant the water was highly variable, and very difficult to treat by conventional methods. Starting with demonstration that soil based reed beds were the ideal solution as they were versatile enough to handle the

An old industrial site that had been used as a pesticide research and development facility required remediation. The ground and underlying aquifer was heavily contaminated with pesticides and other chemicals. Initially the contaminated soils were removed and partially treated by thermal desorption. Next, a groundwater treatment system was installed. This consisted of 4 reed beds

Turlinjah is a small community of 70 people on the NSW South coast of Australia. Previously sewage was collected in septic tanks located less than 200 meters from extensive oyster leases in the Tuross Lake. There was concern about the untreated septic discharge into this sensitive receiving environment. Monitoring of the area showed levels

iEnvi was engaged by an inner western Sydney Council to undertake a soil stockpile reuse investigation at a vacant property. It was important to determine the contamination condition of the 1,800 m3 soil stockpile before reuse options could be identified. Targeted test pits were excavated throughout the soil stockpile and sampled. Based on the findings

In early 2019, iEnvi completed multiple preliminary site and soil investigations at recreational use parks in inner Sydney suburbs prior to a series of playground upgrades and installations. From a review of historical information and soil sampling, iEnvi identified that the soil at the parks was potentially exposed to contaminants within the last 50 years.
