Summary While there is some debate about the definition of abandoned gas stations as to how old does a gas station have to be operational to be declared as abandoned, we can generally agree with the notion that an abandoned gas station is presents a significant risk to the community. What we do? We use bio-remediation products AgroRemed and HydroRemed as part of our cleanup protocol. Results The tanks were removed in 2018, we closed this project on Jan 17th 2022.

Some thoughts on Haskell and purity. A friend of mine introduced me to CPS a few weeks ago and this got me interested in Andrew Appel’s Modern Compiler Implementation in ML that implements a compiler for Tiger programming language. The chapter on Static-single assignment or SSA form was instructive because it offered an alternative perspective on why purity in functional languages matter. SSA is a property of an intermediate representation, that requires that each variable be assigned only once, and be defined before it is used.

FOWA Extraction Process This post discusses the energy equation for the FOWA process based on some observations and assumptions. Briefly, the process allows an asphalt producer to extract bunker fuel - test 1, bunker fuel - test 2 - S - 441 ppm and bunker fuel - test3 - S - 291 ppm [from asphalt1. The links to tests 2 and tests 3 show that the sulfur content in the extracted oil is between 291 - 441 ppm less than the 5000 ppm (or 0.
