    Lordship Recreation Ground (Downstream) by Caroline Jepson

    The appearance of the Moselle Brook has deteriorated since the December and January testing when the sewage fungus had disappeared. The sewage fungus attached to the vegetation on the edges of the Brook was very visible as seen in the photos attached. The ammonia reading was higher than the previous two readings, although still historically on the law side. The phosphate reading had also increased, which was not surprising considering the return on the sewage fungus.
