Birthday cards, an employee handbook, letters about a couple getting divorced and two passport-sized photos of a woman were among the items dumped at the side of a country road.
They were found at the bend in Cupid Green Lane just before its junction with Dodds Lane, near Grovehill.
Stan Scrooby, 35, who lives nearby, said: “It’s ridiculous. Stuff gets dumped here a lot, because it’s unwatched.”
He said it’s an attractive spot for fly-tippers, as there is no CCTV, so they think they can get away with it.
He said: “They do not think further than their noses about anything other than themselves. It’s selfish.
“When I found it, I was fuming.”
Among the items dumped was a Mitie employee handbook. The FTSE 250 firm looks after social housing for Dacorum Borough Council.
There was also a letter from a local primary school, among other correspondence.
The Hemel Hempstead Household Waste Recycling Centre, where rubbish can be dumped legitimately, is not far from Cupid Green Lane in Eastman Way, Maylands Industrial Estate.
Dacorum Borough Council is responsible for removing fly-tipped rubbish, which it says it usually does in less than a week.
Environmental protection and housing team leader Nick Egerton said: “Where we find evidence we will invite potential perpetrators to an interview.
“Although fly tipping is relatively low in Dacorum, because of our proactive approach to tackling and subsequent legal action, we take it very seriously and the maximum penalty is £50,000.
“To help us tackle illegal fly-tipping we have a mobile CCTV camera which can be used in fly-tipping hotspots.”
