Hawaii's unique geology poses many problems with finding "any indication" of pollution.... The fractures, tubes & the different lava layers make it very hard to trace effluent from its' source (have heard that some environmental groups have done dye tracing from some properties, but have nor seen the data). The standard for most cesspool/septic failures does not really work here (most are based on percolation tests & effluent soil tests....hard when there are not standard deposition layers & a lack of soil....esp. soil that is very nitrogen poor, as some effluent tests are for nitrogens....)
