“…Early methods for the analysis of STP were based on the separation of phosphate species using an ionexchange column, followed by acid hydrolysis of the STP to orthophosphate, which was then determined colorimetrically as a molybdenum blue complex (Lindenbaum et al 1954;Grande & Beukamp 1956;Lundgren & Loeb 1961). Most of these workers were involved in the analysis of fairly high concentrations of STP.…”

“…Most of these workers were involved in the analysis of fairly high concentrations of STP. Lundgren & Loeb (1961) suggested that STP may spontaneously degrade below 4 g m 3 . However, Morita & Uehiro (1981) used high pressure liquid chromatography (HPLC) to analyse STP to low levels, and provided figures which suggest a concentration detection limit of c. 0.3 g nT 3 .…”

“…However, Morita & Uehiro (1981) used high pressure liquid chromatography (HPLC) to analyse STP to low levels, and provided figures which suggest a concentration detection limit of c. 0.3 g nT 3 . More recently, Close et al (1989) adapted the method of Lundgren & Loeb (1961) for use on an autoanalyser. This adaptation gave a detection limit for STP of 1 mgmP resence infaeces, effluents, and contaminated water There appears to be very little published information on STP levels in sewage and receiving waters.…”

Management of faecal contamination of water would be improved if sources could be accurately identified through water analysis. Human faeces are generally perceived as constituting a greater human health risk than animal faeces, but reliable epidemiological evidence is lacking. United States waterborne disease data suggest that humanspecific enteric viruses account for over half the documented outbreaks. However, in New Zealand, where there is a high grazing animal:human ratio (increasing the relative importance of watertransmissible zoonoses), it seems prudent to assume that human and animal faecal pollution both constitute a risk to human health. Irrespective of the relative risks, the ability to identify sources would assist in overall management of microbial water quality. Faecal streptococci do not appear to provide reliable faecal source identification. Human and animal sources, respectively, maybe distinguishable by two tests on Bifidobacterium spp.-growth at 45°C in trypticase phytone yeast broth and sorbitol fermentation. Different species of Bacteroides tend to be present in humans and animals, but poor survival in water is a problem. Phages of the M97014

of alkylamine-silanized metal oxide electrode. We can draw from this the intimation that a redox reagent bound to the alkylamine-silane may find itself in a spectrum of slightly different chemical environments. The redox reagent may as a consequence exhibit a spectrum of formal electrochemical potentials, which in turn has the effect of broadening the electrochemical surface wave observed fur the reagent. To what extent broadening we have observed in surface waves on alkylamine-silanized electrodes is due to this chemical heterogeneity as opposed to interactive effects within the chemically bound layer (62) or to both, remains tu be resulved.

Two indicators of septic tank effluent were measured in a groundwater quality survey of an unsewered, semi-rural community. The selected indicators were fluorescent whitening agents and sodium tripolyphosphate (STP). Other water quality determinands indicated that the groundwater was of good chemical quality for drinking purposes but, in about half of the wells, levels of total coliform bacteria exceeded New Zealand Board of Health recommended guidelines for drinking water. Fluorescent whitening agents and/or STP were detected in 17% of the samples and concentrations of STP correlated significantly (P<0.001) with levels of faecal coliform bacteria. The study showed that the selected indicators could be detected in groundwater used for domestic purposes, and could be used for assessing whether septic tanks were implicated in contaminated domestic wells.
