Water hyacinth plants were grown in both water from the Hartbeespoort Dam and Hoagland Solution to test the effect of growth medium 'purity' on hyacinth growth. Another set of vessels containing Hartbeespoort Dam water only, without a hyacinth plant, was used to observe the remediation potential ...
