I fear it was all too common, this article from The Times in 1875 describes the churchyard where many of my ancestors are buried.

"EARTH TO EARTH." - At a vestry meeting at East and West Looe, Cornwall on Saturday, the chairman, the Rev. H. Mayo, vicar of Talland, described the state of the churchyard at Talland, which is the burial place for West Looe. Over 8,000 bodies had been interred, he said, in a little more than half an acre of ground. The usual depth of graves was 4 1/2 ft. deep, deeper graves being out of the question, owing to the friable nature of the soil, which was being continually turned over. There are no spaces between the graves, and whenever a person had to be buried the remains of others had by necessity to be disturbed. The sexton had a curious mode of determining whether or not he would be safe to open any particular spot. He drove a long bar down to the requisite depth, and if he met with no substantial obstacle, the grave was dug. Only last week, the chairman said, he saw a woman beside a newly opened grave in bitter distress, because the remains of one dear to her had been ruthlessly dug up and exposed. The repeated burials had raised the level to such a point that the church appeared to be in a pit and the polluted atmosphere rendered the sacred edifice unfit for public service. There was constantly oozing from the graves in the higher part of the yard a horrible slime, which came on the floor of the belfry. He was obliged to keep disinfectants for the safety of the ringers. Fresh primroses which were gathered and placed in the church for decoration on Easter Saturday, were almost black by the following evening, and a scientific friend had told him it was owing to the presence of sulphuratted hydrogen in the atmosphere, in such quantities as would endanger human life. On Ash Wednesday so fetid was the air in the church that the congregation was obliged to withdraw. Under these circumstances it is not suprising that Dr. Holland, the Government Inspector, is of opinion that something must be done to present a cemetery for the united townships; the ratepayers, however, are determined to put off the evil day of spending as long as possible, and a motion in favour of taking steps for the formation of a Burial Board was defeated. Dr. Holland will report to the Home Secretary.
Incidentally a civil churchyard for West Looe was a long time coming & in 1894 a cemetery was also opened in nearby Polperro. The ratepayers really were reluctant to spend money despite the appalling conditions.
