Water Quality Testing

We have an in-house, full-service water quality laboratory, that can test for a variety of needs. We can do residential as well as commercial testing, resale, use and occupancy, and quarterly testing for schools, restaurants, day cares, etc.
 
All of our employees are state certified water samplers.

Our laboratory can test for the the following:

  • Bacteria
  • Hardness
  • Nitrates as N
  • Nitrites as N
  • pH
  • Chlorides
  • Turbidity
  • Lead & Iron
  • Metals
  • Radon
  • Radionuclides
  • VOC (including MTBE)
  • SOC (pesticides and herbicides)

Well Yield Testing

We can perform a well yield test in houses or on vacant lots, for real estate transactions, refinance, or for your own information. We do a 3-6 hour yield test in accordance with Baltimore County requirements.

The State minimum requirement for new construction is 1.0 gpm. Baltimore County requires a yield of at least 1.0 gpm for the transfer of property.

Caswell Testing can also perform 24, 48, 72 and 96-hour well yield tests required for water appropriation permits.

Chlorinations

Wells that fail a bacteria test may be sanitized by a chlorination. We can perform either a regular or forced chlorination depending on your well needs. 
 
A forced chlorination is when we bring 550 gallons of heavily chlorinated water and wash down the inside of the casing. This method is very effective in sanitizing wells that have a heavy amount of bacteria, wells with a high yield or wells that are over 300’ deep.
